ABB S203M C40 Miniature Circuit Breaker, 3 Pole, Type C, 10kA/15kA Breaking Capacity, 40 Amp Current (2CDS273001R0404)

THREE-PHASE CIRCUIT PROTECTION – ABB S203M-C40 3-pole 40A miniature circuit breaker protects electrical circuits from overload and short-circuit faults. Ideal for DIN rail distribution boards, control panels, switchboards and industrial power systems. TYPE C TRIPPING PERFORMANCE – Type C characteristic trips at 5–10× rated current, allowing moderate inrush currents from motors, compressors, pumps and lighting circuits without nuisance tripping in automation and machinery installations. EASY DIN RAIL INSTALLATION – Compact 3-pole breaker clips onto standard DIN rails in switchboards and distribution boards. Screw terminals provide secure wiring and compatibility with ABB System pro M Compact accessories and busbar systems. RELIABLE FAULT INTERRUPTION – 10kA breaking capacity safely interrupts high fault currents while thermal overload and magnetic short-circuit protection help protect wiring, equipment, electrical panels and industrial distribution systems. ABB PROTECTA PLUS SYSTEM – Part of the ABB Protecta Plus modular distribution system for indoor installations, offering high internal accessibility, removable internal modules for simplified wiring, insulated neutral and earth bars, and an expandable cabinet concept for flexible electrical distribution solutions.
