ABB Protecta Plus S203M-D32 Miniature Circuit Breaker is a high-quality 3-pole protective device designed to protect electrical circuits from overload and short-circuit faults. It is part of the ABB System pro M Compact S200M series, widely used in residential, commercial and industrial electrical installations. This breaker features a 32A current rating with Type D tripping characteristics, making it ideal for circuits with high inrush currents such as motors, compressors, transformers and industrial equipment. The device incorporates two tripping mechanisms: delayed thermal tripping for overload protection and electromechanical magnetic tripping for short circuits. With a 10kA breaking capacity, it safely interrupts fault currents and helps protect electrical systems and connected equipment. The compact DIN rail mounting design allows quick installation in switchboards and distribution panels. It complies with IEC/EN 60898-1 and IEC/EN 60947-2 standards and is compatible with ABB System pro M Compact accessories for expanded functionality. 3-pole miniature circuit breaker 32A current rating Type D tripping characteristic for inductive loads 10kA short-circuit breaking capacity Rated voltage: 400V AC / 125V DC DIN rail mounting for easy installation Thermal and magnetic overload protection Suitable for commercial and industrial power systems
