ABB Protecta Plus S203M-C16 Miniature Circuit Breaker • 3 Pole • 16A Type C • 440V AC / 12V DC • 10kA Breaking Capacity • DIN Rail Mount • System pro M Compact • Industrial MCB • 2CDS273001R0164

THREE-PHASE CIRCUIT PROTECTION – ABB S203M-C16 3-pole 16A miniature circuit breaker protects circuits from overload and short-circuit faults. Ideal for DIN rail distribution boards, switchboards, control panels and industrial electrical systems.

TYPE C TRIPPING PERFORMANCE – Type C tripping curve trips at 5–10× rated current, allowing moderate inrush loads from motors, pumps, compressors and lighting circuits. Suitable for automation panels, machinery equipment and electrical installations.

DIN RAIL INSTALLATION – Compact 3-pole breaker snaps onto standard DIN rails for quick installation in switchboards and distribution boards. Finger-safe screw terminals ensure secure wiring and compatibility with ABB System pro M Compact accessories.

10KA BREAKING CAPACITY – High 10kA breaking capacity safely interrupts fault currents during overload or short circuits. Thermal overload and magnetic short-circuit protection help safeguard wiring, equipment and distribution boards.

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.
