Product Description
This device is a motor protector circuit breaker engineered for precise thermal and magnetic protection of small motors. It provides an adjustable full-load current setting via an on/off rotary dial, supporting a thermal overload release range of 0.22 to 0.32 A for tailored coordination with motor nameplate ratings. Built-in heater elements deliver reliable overload protection while magnetic trip elements respond to short-circuit events, enabling compact branch protection within control panels. The unit is classified as Class 10 for trip characteristics and uses the S0 frame size, aligning with common Siemens Sirius coordination schemes and accessories. It is suitable for integration with contactors and auxiliary blocks in motor starter assemblies. Typical applications include machine tools, conveyors, and light-duty automation where precise low-current motor protection is required. Package and compliance details indicate industrial-grade construction with standard take-back obligations and RoHS alignment, ensuring compatibility with professional installation and maintenance practices.
