This Schurter Inc. 4430.0012 is a thermal circuit breaker with a 2-pole configuration, suitable for equipment protection applications. It offers a rated current of 6A and operates at 240 VAC or 60 VDC. The breaker features a rocker actuation type and a panel mount design for easy integration into systems.
Key electrical specifications include a conditional short circuit capacity of 1 kA at 240 VAC and various Icn ratings depending on current and voltage conditions. The device is built for reliability with a mechanical lifetime of 50,000 switching cycles and electrical lifetime ratings of 50,000 cycles for both AC and DC operation at 1x Ir. Overload capability is specified as a minimum of 40 trips at 6x Ir for AC and 4x Ir for DC.
Environmental and mechanical robustness are supported by an IP40 degree of protection on the front side, extendable to IP54 with a protection cover. It operates within a temperature range of -10 °C to 55 °C and has undergone vibration and shock resistance testing according to IEC standards. Approvals include CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.
