The Schurter Inc. 4430.2802 is a 2-pole thermal circuit breaker featuring rocker actuation and a panel mount design. It provides thermal overload protection with a rated current range of 0.05 to 20A AC and a voltage rating of 240 VAC or 60 VDC.
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 type (AC/DC). The breaker has a mechanical lifetime of 50,000 switching cycles and offers overload protection with a minimum of 40 trips at 6x Ir for AC and 4x Ir for DC.
Environmental specifications 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 and storage temperature range is -10°C to 55°C. The device has undergone vibration resistance testing up to 10 G @ 60 - 500 Hz and shock resistance testing of 30 G / 18 ms.
Applications for this circuit breaker include power tools, industrial appliances, power supplies, equipment for construction, and cleaning equipment.
The rated voltage is 240 VAC and 60 VDC.
The allowable operating temperature range is -10°C to 55°C.
It uses a rocker actuation type.
The dielectric strength is 4 kVAC.
The mechanical lifetime is 50,000 switching cycles.
It is panel mounted with either quick connect terminals (6.3 x 0.8 mm) or screw clamp terminals (M3.5 x 6 mm).
The front side has an IP40 degree of protection, which can be upgraded to IP54 with a factory-mounted protection cover.
