This Schurter Inc. 4430.2674 is a 2-pole thermal circuit breaker designed for equipment protection. It features a positively trip-free release mechanism and rocker actuation, available in non-illuminated or illuminated versions. The breaker supports snap-in mounting and offers quick connect or screw clamp terminals.
Key electrical specifications include a rated voltage of 240 VAC and 60 VDC, with a rated current range from 0.05 A to 20 A. It has a conditional short circuit capacity of 1 kA at 240 VAC. The device is built for durability with a mechanical lifetime of 50,000 switching cycles and overload protection rated for a minimum of 40 trips at 6x Ir for AC and 4x Ir for DC.
Environmental and mechanical resilience are ensured with a degree of protection of IP40 (IP54 with cover), a dielectric strength of 4 kVAC, and insulation resistance greater than 100 MΩ at 500 VDC. It operates reliably within a temperature range of -10°C to 55°C and withstands significant vibration and shock resistance.
Applications for this circuit breaker include power tools, industrial appliances, power supplies, equipment for construction, and cleaning equipment. It holds approvals from VDE, UL, and CCC.
