The 4430.0963 thermal circuit breaker provides robust 2-pole overload protection for industrial and commercial equipment. Manufactured by Schurter Inc., this device operates at a rated current of 10A with voltage ratings up to 240VAC and 60VDC. It utilizes a positively trip-free thermal release mechanism paired with a durable rocker actuator for clear manual control and reset functionality.
Designed for snap-in panel mounting, the unit features quick-connect terminals measuring 6.3 x 0.8 mm or optional screw clamp terminals for secure wiring. The front face offers an IP40 degree of protection, which increases to IP54 when equipped with a factory-mounted protective cover. Electrical characteristics include a dielectric strength of 4 kVAC and insulation resistance exceeding 100 MΩ at 500VDC.
The breaker withstands mechanical switching lifetimes of 50,000 cycles and meets rigorous vibration and shock standards. Approved by major international testing bodies including UL, VDE, and CCC, it is suitable for power tools, industrial appliances, construction equipment, and cleaning machinery.
