The Schurter Inc. T9-611 series thermal circuit breaker, part number 4404.0005, is designed for reliable overcurrent protection in various applications. This 1-pole breaker offers a rated current of 12A and can handle AC voltages up to 240V and DC voltages up to 48/32V.
Featuring a snap-in mounting type for front-side installation into panels 0.8-2.0mm thick, this circuit breaker is suitable for applications requiring a compact and secure protection device. The actuator type is push-to-reset, allowing for easy manual reset after a trip event. The breaker is built to withstand a conditional short circuit capacity of 2 kA at 240VAC.
With an ingress protection rating of IP40 on the front side, it offers protection against solid objects larger than 1mm. The device meets endurance standards, with typical endurance rated at 2500 switching cycles at 150% Ir, cos φ 0.9 for 3-8A variants and 6000 cycles for 10-16A variants. It also boasts a dielectric strength of 1500 VAC and an insulation resistance greater than 1000 MΩ at 500 VDC.
Applications for this thermal circuit breaker include power supplies, uninterruptible power supplies, power tools, industrial appliances, HVAC systems, and household appliances. It is designed according to international standards such as IEC 60934, UL 1077, and CSA C22.2 No. 235.
The rated voltage is 240 VAC and 48/32 VDC.
The rated current is between 3A and 16A.
