ABB Protecta Plus S203M-B6 Miniature Circuit Breaker • 3 Pole • 6A Type B • 440V AC / 12V DC • 10kA Breaking Capacity • DIN Rail Mount • System pro M Compact • Industrial MCB • 2CDS273001R0065

THREE-PHASE CIRCUIT PROTECTION – ABB S203M-B6 3-pole 6A miniature circuit breaker protects circuits from overload and short-circuit faults. Designed for DIN rail distribution boards and switchboards in commercial and industrial installations.

TYPE B TRIPPING CURVE – Type B tripping operates at 3–5× rated current, providing quick response to overloads and short circuits. Suitable for circuits with low inrush current such as lighting systems, heating equipment and general electrical loads.

DIN RAIL INSTALLATION – Compact 3-pole breaker mounts on standard DIN rails in switchboards and electrical panels. Screw terminals secure conductors while the contact position indicator allows quick visual status checks during operation or service.

10KA BREAKING CAPACITY – Rated 10kA to safely interrupt high fault currents during overload or short circuit events. Thermal and magnetic trip mechanisms quickly disconnect power to help protect wiring, connected equipment and electrical 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.
