3-125-263 Description

Short technical summary and product information.

The Schurter TA36 Rocker series circuit breaker, part number 3-125-263, is designed for thermal and thermal-magnetic protection. This 1-pole breaker offers a rated current range of 0.05 to 20A AC and a voltage rating of 240 VAC (IEC) or 277 VAC (UL/CSA). It features a rocker actuation type and a panel mount for easy installation.

 

With a mechanical lifetime of 50,000 switching cycles and specific AC and DC overload trip capabilities, this circuit breaker is built for reliability. It operates within a temperature range of -30°C to 60°C and meets IP40 degree of protection on the front side. The TA36 Rocker is suitable for various industrial applications, including power tools, medical equipment, industrial appliances, and construction equipment.

 

Key technical data includes a conditional short circuit capacity of 2 kA at 240 VAC (IEC 60934) and dielectric strength exceeding 2.5 kV at 50 Hz. The insulation resistance is greater than 100 MΩ at 500 VDC. The breaker also exhibits resistance to vibration and shock according to IEC standards.
