Description:
This Siemens 5SJ43257HG41 is a 3-pole miniature circuit breaker designed for reliable circuit protection. It operates with a C-trip characteristic and has a rated current of 25A. The breaker is suitable for AC applications up to 240V and offers a short-circuit breaking capacity of 14kA according to UL 1077 and CSA C22.2 No.235.

With a mechanical service life of typically 10,000 switching cycles, this circuit breaker is built for durability. It features a compact design with dimensions of 110 mm height, 54 mm width, and 70 mm depth, fitting into 3 modular width units. The protection class is IP20 with connected conductors and IP40 in the handle range.

Connections are made via combined terminals, and it supports finely stranded conductors with core end processing from 0.75 mm² to 25 mm². The tightening torque for screw-type terminals is a maximum of 3.5 N·m. This component is also noted as being halogen-free and silicon-free.

Suitable for mechanical engineering and industrial applications, the 5SJ43257HG41 provides essential protection against overcurrents and short circuits.
