£145.66
The ABB S303P-C32 is a high-performance three-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical installations against overloads and short circuits. Part of the trusted ABB System pro M compact S300P series, it combines dependable operation, high fault interruption capability and a compact modular design.
Manufactured in accordance with international IEC, UL and CSA product standards, the S303P-C32 is suitable for installation within switchboards, distribution boards and industrial control panels. Its dual DIN rail release, integrated trip indication and fail-safe terminals help simplify installation, inspection and maintenance.
Featuring a 32 A rated current, a C curve tripping characteristic and a rated ultimate short-circuit breaking capacity of 25 kA at 415 V AC, this miniature circuit breaker is well suited to circuits supplying mixed resistive and inductive loads, including lighting, socket outlets, pumps, compressors and small motors.
The ABB S303P-C32 uses thermal and magnetic tripping mechanisms to disconnect a circuit when an overload or short circuit occurs. This helps protect conductors, switchgear and connected equipment from excessive current and the resulting thermal or mechanical damage.
Its C curve characteristic permits moderate short-duration inrush currents without unnecessary operation while retaining rapid response during genuine fault conditions. This makes the breaker particularly suitable for general distribution circuits and equipment containing motors, transformers or other inductive components.
