This Schurter Inc. 4400.0169 is a thermal circuit breaker designed for equipment protection. It features a compact, snap-in design with a reset type actuator and quick connect terminals.
Key electrical specifications include a rated voltage of 240 VAC and 48 VDC, with a rated current range of 0.05 to 16 A. The breaker offers a conditional short circuit capacity of 2 kA at 240 VAC. It is designed for a minimum of 40 trips at 6x Ir under IEC conditions and 50 trips at 1.5x Ir under UL/CSA conditions.
The operating temperature range is -5 °C to 60 °C. The circuit breaker has a degree of protection of IP40 on the front side and meets various vibration and shock resistance standards.
Applications for this circuit breaker include power tools, household equipment, power supplies and chargers, and industrial appliances. It is designed according to IEC 60934 and UL 1077 standards.
The rated voltage is 240 VAC and 48 VDC. The rated current is 1 A.
The allowable operating temperature range is -5°C to 60°C.
Conditional short circuit capacity is 2 kA at 240 VAC. For rated currents below 6.5 A at 240 VAC, the short circuit capacity is 8 x In. For rated currents of 6.5 A or above, it is 96 A.
It is approved under CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.
It uses a push-to-reset actuator and is panel mounted.
Dielectric strength is greater than 1.5 kV at 50 Hz and greater than 2.5 kV for impulse 1.2/50 μs.
