The Schurter Inc. 4430.2686 is a thermal circuit breaker featuring a 2-pole configuration and a panel mount design. It provides thermal overload protection with a rated current of 20A and a rated voltage of 240VAC. The breaker is designed for positively trip-free release and offers a high degree of configurability.
Key technical specifications include a rated voltage of 240 VAC and 60 VDC, with a rated current range of 0.05 to 20 A. It has a conditional short circuit capacity of 1 kA at 240 VAC. The device offers a dielectric strength of 4 kVAC and an insulation resistance greater than 100 MΩ at 500 VDC. Mechanical lifetime is rated at 50,000 switching cycles.
Environmental and operational parameters include an operating temperature range of -10 °C to 55 °C and a storage temperature range of -10 °C to 55 °C. It meets IP40 degree of protection on the front side, or IP54 with a factory-mounted protection cover. Vibration resistance is specified up to ± 0.75 mm @ 5-60 Hz and 10 G @ 60-500 Hz. Shock resistance is 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. It holds approvals from CSA, EN, GB, IEC, and UL.
