Schurter T9 Circuit Breaker Now Available for PCB Mounting

Schurter’s T9 fuseholder style thermal 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 new T9 Model T9-818 for PCB mounting fills a gap in Schurter’s T9 product line and the market. The T9 series features dimensions comparable to those of traditional fuseholders and is similarly designed for direct placement on circuit boards. Schurter’s existing T9 series features quick connect terminals for front and rear snap in panel mounting, as well as a threaded neck mounting style.

The shape of the T9 circuit breaker is very similar to that of a fuseholder and thus offers an excellent alternative to 5×20 fuses and their respective fuseholders, where current surges can lead to premature opening or aging over time. In contrast, circuit breakers prevent unnecessary down time by eliminating the need for changing fuses, as well as the risk of inadvertently inserting a fuse with the incorrect current rating, which may lead to associated 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 on the button. Typical application areas for circuit breakers include use in power supplies, UPS systems, PDU’s, electric tools, industrial applications, medical diagnostic equipment, analysis systems, lighting fixtures, HVAC products as well as equipment for sports and leisure activities. Rated current ranges from 3-15 A at 240 VAC and 48/32 VDC. The T9 product line carries UL, VDE and CCC approvals.
