ABB S203P-B32 three pole 32 A B curve miniature circuit breaker from the System pro M compact S200P range, designed for reliable overload and short-circuit protection in commercial and industrial electrical installations.
The ABB S203P-B32 is a high-performance three-pole miniature circuit breaker (MCB) from the ABB System pro M compact S200P series, designed to provide reliable protection against overloads and short circuits in commercial and industrial electrical installations. Its compact DIN rail mounted design makes it suitable for distribution boards, control panels and three-phase electrical systems where dependable circuit protection is required.
This circuit breaker features a B curve tripping characteristic, making it suitable for circuits with lower inrush currents. It is commonly used for resistive loads, lighting circuits, heating circuits, general distribution and commercial power circuits where fast and reliable fault disconnection is important.
With a 32 A rated current, three-pole configuration and 15 kA breaking capacity, the S203P-B32 provides robust protection for three-phase circuits while maintaining the installation flexibility expected from ABB’s professional miniature circuit breaker range.
The ABB S203P-B32 protects electrical circuits by automatically disconnecting the supply during overload or short-circuit conditions. Its delayed thermal tripping mechanism protects against sustained overloads, while the electromechanical magnetic trip mechanism provides rapid disconnection during short-circuit faults.
The B curve characteristic provides fast operation for circuits with lower inrush currents, helping protect cables, loads and electrical equipment in commercial and industrial installations.
