Siemens AG 3VU1300-1MH00 Motor Circuit Breaker

Siemens 3VU1300-1MH00 is a three-pole motor protection circuit breaker (MPCB) in the SENTRON 3VU family that provides motor protection up to 25 A. It features an adjustable thermal-magnetic trip in the 1.6 to 2.4 A range, with an auxiliary contact pair (1 normally open and 1 normally closed) for signaling, and screw-terminal wiring with an A-release configuration for motor-control circuits. Designed for integration with Siemens motor-control systems and three-phase starter assemblies, this unit protects individual motors within panel installations while enabling reliable disconnection and status feedback. Typical applications include industrial motor feeders and drive-powered machinery that require compact, coordinated protection in a 3-pole package.
