Schurter's T9 fuseholder style circuit breaker series is now expanded to include a version for vertical PCB mounting. The new T9-817 model completes the existing range, which includes a horizontal PCB version, and three different panel mount styles. The full range of mounting styles provides a form and fit alternative to equivalent closed fuseholders.
The T9 family of thermal circuit breakers provides an array of mounting styles alternative to industry standard closed fuseholders, including vertical and horizontal mounted PCB types, and three different panel mount styles with quick connect terminals: snap in or nut fastened, including a threaded neck rear-mount style. The newest addition, T9-817 PCB for vertical PCB mounting, reduces assembly costs and saves board space, by eliminating assembly hardware and wires. It sports a slim design and a small cylindrical push-to-reset button, which protrudes minimally through the panel opening. A spring pushes the button out further when the device trips.
Circuit breakers are an ideal alternative to fuses, since fuses are known to age, due to pulse or high surge currents, and thus trip prematurely. Circuit breakers prevent unnecessary down time by eliminat-ing the need for fuse replacement, as well as the associated risk of inadvertently inserting a fuse with the incorrect current rating. The T9 series thermal circuit breaker is therefore intended as an alternative to 5x20 or 6.3x32 mm fuses used with closed fuseholders.
Typical applications for circuit breakers include power supplies, UPS systems, PDUs, electric tools, mo-tor drive applications, medical diagnostic equipment, commercial kitchen appliances, lighting fixtures, HVAC products as well as equipment for sports and leisure activities. The T9 series is also available on request with glow-wire tested (GWT) materials and is therefore suitable for unattended household appli-ances. The T9 product line conforms to UL 1077, CSA C22.2 235 and IEC 60934 standards. It is cURus, VDE and CCC approved.

With a long history of innovation in the connector and EMC marketplace, Schurter expands its range of power entry modules with the introduction of the FMAD and FMAB CEE Connectors, featuring a first of its kind integrated line filter for 1- and 3-Phase industrial and power distribution applications. The integrated filter optimizes suppression of conducted emissions by eliminating cables between the inlet and filter.
The CEE connectors according IEC 60309 are used all over the world for industrial applications and power distribution. The single and three phase connectors can be used for any application with a detachable power cord. Today, noise generating electronics used in machines drive demand for EMI
suppression filters in order to meet international EMC standards. This filter is typically mounted on the metal chassis for optimal performance.
Traditionally, wires are used to connect the power inlet to the EMI filter mounted separately on the chassis. These wires can vary in length and can cause EMC problems with electromagnetic fields generated by a noise source inside the equipment bypassing the filter! The new CEE connector with integrated filter solves this problem by eliminating these wires and making a direct connection between the filtered connector and its metal shield, which is grounded to the panel cut-out. The fully integrated unit can be front or rear panel mounted directly where the power comes into the equipment.
The new FMAB CEE series is suitable for single phase AC applications. It extends the power entry module concept outlined in IEC 60320, where power input is limited to 16 A. Both the FMAB CEE and the FMAD CEE, which is designed for three phase applications, are rated from 16 up to 32 amperes. They are designed and approved according IEC 60309, UL 1283 and CSA 22.2 no. 8. The voltage rating is 250 VAC (IEC, UL, CSA) and 110 / 125 VAC (UL, CSA). The new filter series are suitable for use in industrial appliances exposed to temperatures ranging from -40 to +85C. Screw terminals provide for ease of installation.

The fuseholder standard IEC/EN 60127-6 has been revised to improve fire safety. Effective in October 2017, manufacturers of fuseholders will only be permitted to market products that have been tested and authorized in accordance with the updated standard. Schurter will offer its customers upgraded solutions by the deadline.
Requirements defined for the household appliance standard IEC 60335-1 are also being applied to the fuseholder standard IEC 60127-6. So the requirement with regard to the glow-wire resistance of the material is being increased. Schurter has planed the adaption of the products and its requalifying
and is currently deploying it. That means used materials has to be tested and if necessary replaced with new glow-wire resistant material. Thus these components can be used in unattended electrical household appliances after the change-over.
Besides the fuseholders, IEC appliance inlets and power entry modules with and without EMC filters are also affected if they have a fuse drawer. The order number of the products are not touched. Therefore manufactures using Schurter products do not have to change the approvals.
Detailed information about the revised fuseholder standard and Schurters plan for implementation are available upon request.

Nanocrystalline Common Mode Chokes for 1 and 3-Phase Applications Mount on PCB
Schurter expands its wide range of current compensated chokes with high current types for PCB mounting. The new DKIH series is now available with a nanocrystalline ring core, offering 8 times higher inductance performance than ferrite core versions in the same compact dimension. The new product is designed for single and three phase applications with rated currents from 10 to 50 amperes. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMI noise caused by power applications on the PCB.
Like all other aspects of electronic design, the power portion is oftentimes 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.
Traditional block filters might well address these challenges, but their larger package size also presents challenges due to the mentioned space constraints; therefore an asymmetrical effective common mode choke and capacitors mounted on the PCB is a better solution.
The new DKIH-1 series is suitable for single phase AC or DC applications from 10 up to 50 amperes. Light weight and compact, the common mode chokes are easily placed on the PCB with through hole technology (THT). They are designed and approved according IEC 60938, UL 1283 and CSA 22.2 no. 8. The voltage rating is 300 VAC (IEC, UL) and 250 VAC (CSA) with an inductance range of 1.6 to 6.9 mH.
The new DKIH-3 series is suitable for three phase AC applications from 10 up to 50 amperes. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC with an inductance range of 0.7 to 10.8 mH, making them suitable for many applications such as UPS systems, switching power supplies, charge stations for electric vehicles and frequency converters for energy storage.
The DKIH-1 and -3 have a wide temperature range of -40 to +100 °C. They are available with a standard pin out or customer specific pin out. Variations in the winding are also available upon request.

The filter series is particularly suitable for equipment with high symmetrical interferences, such as devices with semiconductors that control high-power equipment, including professional coffee machines, devices with water heaters, and all types of industrial electronics. The compact filters are also suitable for medical equipment and household appliances.
The filter series is fitted with plug-in connections or threaded bolts. A version with wire connections is also available. The metal flange provides easy screw-on mounting.
The series of filters is designed for current levels from 1 A to 60 A at 250 V AC according to IEC and UL standards.The FMAB NEO has ENEC and cURus approvals and is suited for applications according to IEC 60950. Versions are available with small leakage currents <80 μA (M80) or without leakage current <5 μA (M5) for medical equipment according to IEC/UL 60601-1.
