The Schurter Inc. 4430.3743 is a thermal circuit breaker with a 2-pole configuration, suitable for various applications requiring reliable overload protection. It is designed for panel mounting and features a rocker actuation type.
Key electrical specifications include a rated voltage of 240 VAC and 60 VDC, with a rated current range of 0.05 to 20 A. The breaker offers a conditional short circuit capacity of 1 kA at 240 VAC and a short circuit capacity (Icn) of up to 300A at 240 VAC for currents of 3A or higher. It has a mechanical lifetime of 50,000 switching cycles.
Environmental and mechanical data indicate a degree of protection of IP40 on the front side, which can be increased to IP54 with a factory-mounted protection cover. The operating temperature range is -10 °C to 55 °C. The breaker has undergone vibration resistance testing up to 10 G @ 60 - 500 Hz and shock resistance testing of 30 G / 18 ms.
This circuit breaker is suitable for applications such as power tools, industrial appliances, power supplies, equipment for construction, and cleaning equipment.
