The new fuse holder standard IEC/EN 60127-6 Edition 2, requiring increased glow wire resistance, will come into effect the beginning of October 2017. Schurter is ready!

With the updated fuse holder standard IEC / EN 60127-6 Edition 2, more attention is given to the area of fire protection. New requirements focus on the materials being used, which must be glow wire tested according to IEC / EN 60695-2-12 and -13 (GWIT=775°C and GWFI=850°C).

These new requirements are contained in the standard for household appliances IEC/EN 60335-1, which has been a long time established standard, particularly due to the prevalence of such unattended appliances (e.g., coffee machines).

All manufacturers of fuse holders must therefore check the glow wire resistance of the materials being used and, if necessary, replace the material. It is also necessary to update the approvals and to carry out a re-examination by the certification body. In case of a material change, the tests according to UL 4248.1 must also be repeated.

All fuse holders certified Until October 08 2017, SCHURTER will have adapted the complete range of its IEC-certified fuse holders to the new standard, including power entry modules with fuse holders. This will poise SCHURTER as the first manufacturer of fuse holders ready to meet the stringent standard.

All Schurter IEC-certified fuse holders marketed as of October 08 2017 will comply with IEC/EN 60127-6 Edition 2, as well as UL 4248.1, and can therefore be safely installed in all household appliances.

Customer-friendly Schurter has placed great attention on the fact that the same part numbers will be used. This makes it unnecessary for the user to make changes to a parts lists, or be deal with new approvals.

General Rules from VDE
-  The manufacturer will lose VDE approval after October 08 2017 for any parts that do not conform with the new requirements for IEC / EN 60127-6 Edition 2 and therefore must no longer sell those products.

-  All parts the manufacturer already sold to market (i.e. to end-customers, distributors or resellers) before October 08 2017 maintain valid VDE approval.

-  All mixed inventory at end-customers, distributors or resellers can continue to be used or shipped or resold without any limitation.

* Customer-specific time-current tripping characteristic as a function of ambient temperature
* Combination of protection against overcurrent and excessive ambient temperature
* On request qualified according to AEC-Q200

Schurter’s USN 1206 offers a temperature-sensitive SMD fuse suitable for both overcurrent protection and protection against excessive ambient temperatures.

Due to the ever-increasing packing density in power electronics, it is becoming ever challenging to deal with the resulting tighter and hotter board real-estate. Automobile manufacturers increasingly use control units in their products, including power electronics (e.g. ABS modules, annealing time control units and actuators). The trend is to integrate as many functions as possible into the smallest possible space in a single module. The fact that such modules must be protected against overcurrent is self-evident. However, the increasing power density also entails thermal requirements. For this purpose, new approaches are needed to avoid a creeping risk of overheating.

Combination: Current and Temperature

The USN 1206 from SCHURTER is not a pure thermal fuse. It requires a current flow to blow, thus providing protection against overcurrent just as well as any conventional fuse. In addition, it is also designed to protect power semiconductors in automotive applications against over temperature. The fuse has a current-time characteristic which shifts as a function of the ambient temperature. As a result, a specific trigger at a certain threshold value can be achieved increasing temperature.
The USN 1206 from SCHURTER has high I2t values at 32 VDC and a slow blowing characteristic.

Reflow Solderable
The USN 1206 temperature-sensitive SMD fuse is reflowable at 245°C according to IEC 60068-2-58. The epoxy glass housing makes it tight against the potting compound. Thus, the fuse is also suitable for explosion-proof applications according to ATEX / IECEx.

Application Areas
The production and qualification of the fuse is carried out in agreement with the customer according to the requirement profile of the desired time-current trip characteristic as a function of the ambient temperature. The new Schurter USN 1206 is particularly suitable for automotive applications requiring the highest reliability under particularly difficult conditions (heat, vibration, mechanical and cyclic strength). In addition, it is also used wherever temperature-critical processes occur, or even when a specific intrinsic characteristic is required.

Schurter expands its wide range of current compensated chokes with new customer specific variants for 4-wire-applications on PCB. The new DKIH series is now available with ferrite or nanocrystalline ring core. The new product is designed for three phases plus neutral wire applications with rated currents from 10 A to 50 A. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMC noise caused by power applications on the PCB.

Like all other aspects of electronic design, the power portion is often built today using discrete components on printed circuit boards. With the trending integration of components, to achieve smaller and smaller form factors, thermal problems and high currents on the PCB can become a challenge. The resulting EMC interferences can affect adjacent modules because of the lack of spatial separation. Therefore, a compact filter on the circuit board with discrete components is often the best solution. A current-compensated choke with capacitors is the most efficient measure for the suppression of EMC interferences.

The DKIH-4 series is suitable for three phases AC and neutral wire applications from 10 A up to 50 A. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC making them suitable for many applications such as UPS systems, switching power supplies, charge stations for electric vehicles and frequency converters for energy storage.

Schurters's new High Current Fuse, HCF, is an extremely robust SMD fuse, designed using solid-state / thin-film technology. The HCF is especially suited for use in particularly harsh applications, where the reliable interrupt of high currents is critical.

Schurters's experience, acquired from the development of solid-state fuses for the space industry, and the cooperation with ESA, have led to the development of the HCF. The new HCF has a similar structure as the two ESA-certified types Schurter MGA-S and HCSF. Fuses used in Space applications meet the most rigorous performance requirements, with only the most advanced, most reliable technologies available. However, the intensive screening of each individual fuse, which is essential requirement for space applications, is not necessary with the HCF for non-Space applications. This leads to a substantial reduction in the cost per fuse.

Solid State / Thin Film Technology
In contrast to conventional fuses with a melting wire, the HCF has a metallic thin film layer. With this manufacturing technique, a metal layer is applied in conjunction with a so-called sputter. The two form on a glass substrate in an exact micrometer thickness. The resulting fuse element is enclosed with a ceramic housing, that guarantees the necessary stability and interrupt capacity. No harmful substances escape in solid or gaseous form during cutoff of the fuse. This technology also makes the SCHURTER HCF completely impermeable to potting compound, which can be used to achieve a hermetic seal e.g. for use in intrinsically safe applications according to ATEX and IECEx requirements.

High Breaking Capacity
The Schurter HCF has a high breaking capacity of up to 1000 A at 125 VAC resp. 125 VDC with fast response. It covers a rated current range from 5 A to 15 A.

Application Areas
Due to its robust design, the HCF fuse is particularly suited for applications which offer high reliability under particularly difficult conditions (thermal and mechanical shock, cycle endurance, etc.). Examples of possible applications: ATEX- and offshore oil and gas applications, equipment operated in sub-arctic regions, aviation electronics, and certain medical technology, where robust and space saving fuse performance is required. The temperature from -50 °C to 125 °C, as well as a vibration resistance – tested up to 1600g – make the HCF ideal for the most demanding high-performance applications under the most adverse conditions.

10 A IEC Appliance Outlet Type F with integrated light pipes and V-Lock cord retention for smart PDUs

Schhurter improves upon a classic product: the new 6600-5 series IEC outlets are available with integrated light pipes. An intelligent, space and cost-saving solution for PDUs used in data
centers and other multi-distributed power applications.

The human need for information continues to expand at record pace, while continual advancements in information and communications technology (ICT), strive to keep pace with this demand. New data centers continually appear in the most unconventional of places to support this growing demand. These data centers are under constant pressure to improve upon efficiency and reliability under growing regulatory requirements to reduce energy use and cost. Meanwhile, the demand for reliable transmission with increased speed must keep pace. At the base of this modern day economic demand and supply phenomena is an intelligent, reliable power supply and – at the base of that – a simple connector. Schurter is pleased to introduce its IEC outlets with integrated light pipes, which bring a simple yet improved solution to intelligent power distribution.

Today, PDUs often use LEDs mounted in between outlets to display a current status. The high packing density of servers in modern data centers demands the same of power distribution units. With Schurter’s appliance outlet, the integrated light pipes provide space and assembly cost savings over conventional strip designs. Service technicians are able to clearly see which systems are working properly, or respond to required maintenance adjustments. The triggering of the LEDs is freely configurable, wherein each state can be clearly and independently represented. An outlet could, for example, signal an outage with a red LED, or a critical power consumption pattern with a yellow LED.

Optionally the SCHURTER 6600-5 is also available with only one or without light pipe.

In order to prevent against unintentional removal of a power cord, the new sockets offer a pull-out safety device. Depending on the arrangement of the sockets in the bar (horizontally or vertically) the Schurter V-Lock or other cord retention systems with side latches can be used. Both systems are possible with outlets the 6600-5.

The outlet’s snap arms are currently designed for front panel dimensions of 1.7 or 2.0 mm. Versions for 1.0, 1.5 and 2.5 mm will follow shortly.  A 16 A version of the device socket with up to 4 light pipes will be launched in the near future as well.
