ABB Protecta Plus S203M-C50 Miniature Circuit Breaker • 3 Pole • 50A Type C • 440V AC / 12V DC • 10kA Breaking Capacity • DIN Rail Mount • System pro M Compact • Industrial MCB • 2CDS273001R0504

THREE-PHASE CIRCUIT PROTECTION – ABB S203M-C50 3-pole 50A miniature circuit breaker protects electrical circuits from overload and short-circuit faults. Ideal for DIN rail distribution boards, switchboards, control panels and industrial power systems.

TYPE C TRIPPING FOR GENERAL LOADS – Type C tripping curve trips at 5–10× rated current, handling moderate inrush from motors, compressors, lighting circuits and power supplies. Suitable for machinery panels, automation systems and electrical installations.

DIN RAIL PANEL INSTALLATION – Compact 3-pole breaker clips onto standard DIN rails in switchboards, distribution boards and electrical panels. Screw terminals ensure secure wiring and compatibility with ABB System pro M Compact accessories.

THERMAL & MAGNETIC PROTECTION – Dual tripping system combines delayed thermal overload protection with fast magnetic short-circuit interruption. Helps protect wiring, machinery, control circuits and electrical 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.
