The Schurter Inc. 4430.0034 is a thermal circuit breaker designed for reliable overload protection in various applications. This 2-pole device features a rocker actuation type and a rated current of 16A, suitable for AC circuits up to 240V and DC circuits up to 60V.
Key electrical specifications include a conditional short circuit capacity of 1 kA at 240 VAC and a short circuit capacity (Icn) of 300A at 240 VAC for currents 3A or greater. It offers a mechanical lifetime of 50,000 switching cycles and specific overload trip characteristics for both AC and DC operation.
Designed for industrial environments, this circuit breaker has a degree of protection of IP40 on the front side, which can be increased to IP54 with a factory-mounted protection cover. It operates within a temperature range of -10°C to 55°C and meets stringent vibration and shock resistance standards.
Mounting is achieved via a panel mount or snap-in configuration, making it versatile for integration into power supplies, industrial appliances, power tools, and construction equipment.
The rated voltage is 240 VAC and 60 VDC.
The rated current range is 0.05 to 20 A.
It uses rocker actuation.
The allowable operation temperature is -10°C to 55°C.
The degree of protection is IP40 on the front side, and IP54 with a factory-mounted protection cover.
