ST200M Miniature Circuit Breakers

ABB ST200M Miniature Circuit Breakers provide supplementary protection according to UL 1077 of up to 10kA at 480Y/277V_AC and 125V_DC. These devices are ideal for multiple applications and markets and feature an updated switching mechanism and assembly for increased triggering reliability, even under tough conditions. The robust thermoplastic housing material includes durable laser-printed product information for easy identification, and the information remains visible after installation. The contact design uses trip-free snap-action mechanism for improved arc movement and safe, optimized switching. The ST200M series provides easy and safe handling and a profile that matches other modular DIN-rail components. ABB ST200M Miniature Circuit Breakers are halogen free and use materials that comply with EU (RoHS, REACH) standards for sustainability.
