Schurter's T9 fuseholder style circuit breaker series is now expanded to include model T9-818 for PCB mounting. The new model complements the existing T9 series assortment for panel mounting, providing a complete range of mounting styles equivalent to closed fuseholders

The T9 series circuit breaker with the Model T9-818 for PCB mounting fills a gap in the market. The T9 series feature dimensions comparable to those of traditional fuseholders, and is likewise similarly designed for direct placement on circuit boards. SCHURTER’s existing T9 series features quick-connect
terminal types for front and rear snap in panel mounting, as well as thread neck mounting.

As with all PCB mounted components, assembly costs are considerably lower because fewer materials are used and wires are eliminated to fully automate assembly. In addition, the T9-818 is more compact than quick-connect terminal types and thus requires less space. Furthermore, its slim design means the
reset button protrudes only minimally from the front panel. Two mounting pins provide additional mechanical support on the circuit board and protect the solder connections from additional pressure when the reset button is activated.

The shape of the T9 circuit breaker is very similar to that of a fuseholder and thus offers an excellent alternative to 5x20 fuses and their respective fuseholders, where current surges can lead to premature tripping and aging over time. In contrast, circuit breakers prevent unnecessary down time by eliminating the need for changing fuses, as well as the associated risk of inadvertently inserting a fuse with the incorrect current rating, which may lead to equipment damage.

A further advantage of circuit breakers is the reset button, which springs out to indicate when the device trips. Reset is achieved by a simple push
of the button. Typical application areas for circuit breakers include use in power supplies, UPS systems, PDUs, electric tools, industrial applications, medical diagnostic equipment, analysis systems, lighting fixtures, HVAC products as well as equipment for sports and leisure activities. The T9 product line conforms to these standards: UL 1077, CSA C22.2 235 and IEC 60934.

Schurter is expanding the successful UMT-H series of SMD fuses with 13 additional rated currents. The expanded series – which covers rated currents between 160 mA and 10 A – will now protect an even broader range of applications. With a rated breaking capacity of 1500 A, this compact SMD fuse is capable of protecting against short circuits, while providing reliable overcurrent protection.

Schurter now offers the UMT-H in a total of 19 rated currents between 160 mA and 10 A at voltages up to 277 VAC and 250 VDC. The compact SMD fuse stands out with its high breaking capacity of 1500 A at rated voltage. This key feature, among others, makes the square UMT-H a space saving alternative to classic cylindrically shaped cartridge fuses (e.g. 5x20 mm).

Besides a wide range of applications in power circuits and sensors, the UMT-H is particularly well suited for the primary protection of power supply units rated up to 277 VAC. It is also suitable for use in the protection of single phase industrial appliances. The high breaking capacity of 1500 A, the spacing between the end caps of >10 mm and the ability to be potted also make these devices useful in applications according to IEC 60079-11 that involve explosion protection. Examples include first responder equipment, industrial controls exposed to oil and gas environments, and lighting ballasts.

Features and benefits:
- High rated voltages up to 277 VAC / 250 VDC
- High breaking capacity (H) of 1500 A at rated voltage
- Initially six rated currents from 160 mA to 2 A (others will follow)
- Time-lag (T) characteristics according to UL 248-14
- Compact, square design
- No rolling away during PCB assembly and soldering
- Safe interruption at line voltage
- Halogen-free and RoHS-compliant

Applications:
- Primary protection on SMD PCBs
- Industrial electronics
- Sensors
- Power supplies
- Explosion protection (IEC 60079-11)
- Lighting

Schurter offers a broad range of high-quality chip fuses, which were developed specially for low-loss and precise overcurrent protection in secondary circuitry. Six different types, available in chip dimensions from 0402 to 1206, offer compact and effective protection in the event of a fault.

The Schurter chip fuses are available in a number of different current ratings from 50 mA to 25 A at a rated voltage of up to 125 VAC/VDC. Depending on the version and voltage ratings, a breaking capacity of up to 600 A is reached. Thanks to these impressively high values and variety, these chip fuses can be used in a wide range of applications. Chip fuses are especially suitable for mobile and battery-operated devices in sensor technology and industrial electronics.

SCHURTER chip fuses set themselves apart from comparable products through their extremely precise opening times and minimal power dissipation. In addition, their solid construction makes them especially resistant to vibrations and pulse loads. Furthermore, the SMD contacts, some of which are gold-plated, have a positive influence on the wettability, storage life and electrical quality of the chip fuses.

All Schurter chip fuses come with cURus certification. The USI 1206 is additionally VDEapproved, the only chip fuse with this type of certification available in the market. As halogen-free and RoHS-conform fuses, Schurter chip fuses, moreover be used for lead-free soldering
processes.

When it comes to household appliances used in unattended operation, the provisions of standard IEC 60335-1 have in the past few years placed higher requirements regarding glow-wire ignition temperature (GWIT). These more stringent requirements thus also apply to installed components such as power sockets, fuse holders and connectors. For this reason, all components carrying current must meet the requirements of glow-wire tests as specified in IEC 60695-2-12 and -13.

As a leading producer of fuse holders and power sockets, Schurter manufacturers a large number of products made of plastic materials with high glow-wire ratings. These are above all shock-safe fuse holders in the successful FPG series, which are available in a wide range of shapes and sizes as well as fuse blocks for assembly on circuit boards. Power connectors rated for 10 A and 16 A, including with a wide range of assembly types and various terminals, also meet these stricter requirements.

Schurter thus fulfills and exceeds the strict guidelines concerning fire prevention for electrical devices that are operated in households unattended. Which appliances are considered to fall under the «unattended» category and thus need components of this glow-wire category is defined in standard IEC 60335-2. Examples of such appliance types are dishwashers, coffee machines, washing machines and kitchen stoves.
