This Schurter Inc. 4430.2307 is a 2-pole thermal circuit breaker designed for reliable overload protection. It features a rocker actuation type and is suitable for panel mounting.
The device offers a rated voltage of 240 VAC and 60 VDC, with a current rating range of 0.05 to 20 A AC. The tripping type is thermal, ensuring protection against overcurrent conditions. It has a mechanical lifetime of 50,000 switching cycles and an operating temperature range of -10 °C to 55 °C.
Key electrical specifications include a conditional short circuit capacity of 1 kA at AC 240 V and various Icn ratings depending on the current and voltage conditions. The circuit breaker also meets specific degrees of protection, IP40 on the front side and IP54 with a factory-mounted protection cover.
Applications for this circuit breaker include power tools, industrial appliances, power supplies, construction equipment, and cleaning equipment. It is designed for industrial environments and meets multiple approval standards.
The rated voltage is 240 VAC and 60 VDC.
It is panel mounted with a rocker actuator.
The operating temperature range is -10 °C to 55 °C.
It uses a thermal tripping mechanism.
For AC at 240 V, the conditional short circuit capacity is 1 kA. The rated short circuit capacity Icn depends on current: under 3 A, 10xIn; above 3 A, 300 A (max 3 cycles). For DC: under 3 A, 10xIn; above 3 A at 48 VDC, 120 A (max 3 cycles).
The dielectric strength is 4 kVAC.
It complies with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.
