ABB S203P-D32NA System pro M compact S200P miniature circuit breaker with 3P+N configuration, 32 A rated current, D tripping characteristic and 15 kA breaking capacity for industrial and commercial circuit protection.
The ABB S203P-D32NA is a premium 3P+N miniature circuit breaker (MCB) from the ABB System pro M compact S200P series. Designed for dependable overload and short circuit protection, it is ideal for industrial machinery, motor control panels, commercial switchboards and OEM electrical systems where high fault performance and reliable operation are essential.
Featuring a D tripping characteristic and a 32 A rated current, the S203P-D32NA is specifically designed for circuits with high inrush currents, making it ideal for motors, transformers, compressors and other inductive loads. Its advanced current-limiting design helps reduce thermal and mechanical stress during fault conditions, protecting valuable electrical equipment and improving system reliability.
With a 3P+N configuration and a 15 kA breaking capacity at 400 V AC, the S203P-D32NA provides professional-grade protection for demanding three-phase installations. The compact DIN rail mounted design integrates easily into modern electrical distribution boards and control cabinets while remaining compatible with ABB's extensive range of modular accessories.
The ABB S203P-D32NA combines delayed thermal overload protection with rapid electromagnetic short circuit protection to safeguard electrical installations and connected equipment. Its current-limiting construction helps minimise fault energy while improving the safety and longevity of electrical systems.
The D curve characteristic is specifically intended for applications where motors, transformers and other inductive equipment generate high starting currents. This makes the S203P-D32NA an excellent choice for industrial automation, machine building and commercial power distribution.
