The Schurter Inc. 4430.1129 is a thermal circuit breaker featuring a 2-pole configuration and rocker actuation. It is designed for panel mounting and provides protection for circuits operating at up to 240 VAC or 60 VDC.
Key electrical specifications include a rated current range of 0.05 to 20 A AC, a conditional short circuit capacity of 1 kA at 240 VAC, and a short circuit capacity of 300A at 240 VAC for currents 3A and above. The device offers a mechanical lifetime of 50,000 switching cycles and overload trip capabilities.
Environmental and mechanical resilience are supported by a degree of protection of IP40 (IP54 with cover), dielectric strength of 4 kVAC, and insulation resistance greater than 100 MΩ. It operates within a temperature range of -10 °C to 55 °C and withstands significant vibration and shock.
Applications for this circuit breaker include power tools, industrial appliances, power supplies, and equipment for construction and cleaning.
