The Schurter Inc. 4430.2306 is a thermal circuit breaker featuring a 2-pole configuration and a rocker actuation type. It is designed for panel mounting and offers a rated voltage of 240 VAC and 60 VDC, with a rated current range of 0.05 to 20 A.
This circuit breaker provides thermal overload protection with a positively trip-free release. Key electrical specifications include a conditional short circuit capacity of 1 kA at 240 VAC and various short circuit capacities (Icn) depending on the current rating and voltage. It has a dielectric strength of 4 kVAC and an insulation resistance greater than 100 MΩ at 500 VDC.
Mechanical and environmental features include 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. Mechanical lifetime is rated at 50,000 switching cycles.
Applications for this circuit breaker include power tools, industrial appliances, power supplies, equipment for construction, and cleaning equipment. It holds approvals from CSA, EN, GB, IEC, and UL.
