Motor Protection Circuit Breaker, S2 frame, Class 10, 18–25 A

Product Description

This motor protection circuit breaker is a Siemens SIRIUS S2-frame device designed for robust motor protection in industrial control panels. It provides Class 10 thermal characteristics with an adjustable overload setting range of 18 to 25 A, enabling precise matching to motor full-load current. Integrated thermal overload elements and a fixed magnetic short-circuit release deliver coordinated protection while minimizing external components. The unit features a front rotary operator for ON/OFF control and setting, and screw terminals for secure conductor termination. It is suitable for DIN rail mounting in standard enclosures and motor control centers. Typical application power ratings align with fractional to medium horsepower motors across single- and three-phase systems, and the breaker offers standard switching capacity for across-the-line starting. Use it where compact protection, reliable trip performance, and straightforward adjustability are required, or as a legacy replacement for existing SIRIUS 3RV1031 installations.
