ABB ST202M-K25 Safety Relay

ABB ST202M-K25 is a two-pole miniature circuit breaker (MCCB) in ABB’s ST200M family, configured as ST202M-K25 and rated for 25 A with a K-curve trip characteristic. This UL 1077-listed, RoHS-compliant device provides overcurrent protection for circuits within commercial and industrial panelboards and is commonly used as upstream protection for feeders and control circuits in electrical distributions. The part designation 2P and 25A confirms two poles and a 25-amp rating, while the “K” curve indicates a specific inverse-time tripping profile suited to industrial wiring demands, and the ST200M lineage identifies it as part of ABB’s modular, DIN-rail-compatible protection lineup.
