ABB S203C32 three-pole 32 A miniature circuit breaker with a C curve tripping characteristic and 6 kA rated short-circuit capacity for overload and short-circuit protection.
£77.05
The ABB S203C32 is a high-quality 3-pole miniature circuit breaker (MCB) designed to protect electrical circuits, cables and connected equipment against overloads and short circuits. Part of the established ABB System pro M compact S200 series, it provides dependable thermal-magnetic protection for residential, commercial and industrial electrical installations.
Featuring a C curve tripping characteristic, the S203C32 is suitable for circuits with moderate temporary inrush currents. This makes it an effective protection solution for motors, pumps, transformers, HVAC equipment, lighting circuits and other inductive or mixed electrical loads.
With a rated current of 32 A, a 3-pole configuration and a rated operational voltage of 400 V AC, the ABB S203C32 is designed for three-phase distribution systems. Its 6 kA rated short-circuit capacity, current-limiting operation and compact DIN rail format make it suitable for distribution boards, switchgear assemblies and industrial control panels.
The ABB S203C32 uses two complementary tripping mechanisms to protect electrical installations. Its delayed thermal mechanism responds to sustained overloads, while its electromagnetic mechanism rapidly disconnects the circuit when a short circuit occurs.
The C curve characteristic permits moderate temporary current surges without unnecessary tripping. This makes the breaker particularly suitable for circuits supplying motors, pumps, transformers, HVAC equipment and other loads that draw additional current during start-up.
Its current-limiting design helps reduce the peak current and energy released during a fault. This can minimise thermal and mechanical stress on cables, conductors and downstream electrical equipment while improving overall installation safety.
