This Schurter TA45-2R series circuit breaker is a thermal overload protection device designed for 1 or 2 pole applications. It features a positively trip-free release mechanism and a Rocker actuation type. The breaker is suitable for panel mounting via a snap-in version and offers a rated voltage of 240 VAC and 60 VDC, with a rated current range of 0.05 to 20 A.
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. The device offers a degree of protection of IP40 on the front side, which can be increased to IP54 with a factory-mounted protection cover. It has a dielectric strength of 4 kVAC and an insulation resistance greater than 100 MΩ at 500 VDC.
Mechanical and environmental resilience are supported by a mechanical lifetime of 50,000 switching cycles and an operating temperature range of -10 °C to 55 °C. Vibration resistance is specified up to 10 G @ 60 - 500 Hz, and shock resistance is 30 G / 18 ms. The circuit breaker has a weight ranging from 30 g to 50 g.
Applications for this circuit breaker include power tools, industrial appliances, power supplies, and equipment for construction and cleaning. It is compliant with various standards including CSA C22.2 No 235, IEC60934, GB17701, and UL1077.
