The Schurter Inc. 3-128-236 is a thermal circuit breaker designed for equipment protection. It operates with a 6A current rating and offers a voltage rating of 240 VAC (IEC) or 277 VAC (UL/CSA), and 32 VDC (1-pole) or 60 VDC (2-pole).
This 2-pole breaker features a rocker actuation type and a panel mount for easy integration into various systems. It is built with a thermal tripping mechanism and provides a conditional short circuit capacity of 2 kA at 240 VAC.
Key electrical specifications include an insulation resistance greater than 100 MΩ at 500 VDC and a dielectric strength exceeding 2.5 kV at 50 Hz. The operating temperature range is from -30 °C to 60 °C, with a storage temperature range of -40 °C to 60 °C.
Applications for this circuit breaker include power tools, medical and laboratory equipment, industrial appliances, equipment for construction, cleaning equipment, commercial and household kitchen appliances, industrial power systems, and industrial lighting arrays.
The rated AC voltage is 240 VAC (IEC) and 277 VAC (UL/CSA). The rated DC voltage is 60 VDC for 2-pole operation.
The rated current range is 0.05 to 20 A AC, with a magnetic trip option up to 16 A.
The allowable operating temperature range is -30°C to 60°C.
The mechanical lifetime is 50,000 switching cycles for both 1-pole and 2-pole versions.
The front side has IP40 protection according to IEC 60529.
