The Schurter Inc. 4430.3614 is a 2-pole thermal circuit breaker designed for reliable overload protection. It operates with a rated AC voltage of 240 VAC and a rated DC voltage of 60 VDC, handling a current range of 0.05 to 20 A.
This circuit breaker features a thermal tripping mechanism and rocker actuation, providing a positively trip-free release. It is designed for panel mounting and offers a mechanical lifetime of 50,000 switching cycles. The device has a degree of protection of IP40 on the front side, which can be increased to IP54 with a factory-mounted protection cover.
Key technical specifications include a conditional short circuit capacity of 1 kA at 240 VAC and a short circuit capacity (Icn) of up to 300A. It operates within a temperature range of -10 °C to 55 °C and has a weight between 30 g and 50 g.
Applications for this circuit breaker include power tools, industrial appliances, power supplies, and equipment for construction and cleaning. It is approved by CSA, EN, GB, IEC, and UL standards.
The operating voltage is 240 VAC and 60 VDC.
It has a panel mount design with a rocker actuator.
The operating temperature range is -10 to 55 °C.
