£180.45
The ABB S303P-Z6 (2CDS383001R0378) is a premium three-pole miniature circuit breaker (MCB) engineered to provide dependable protection against overloads and short circuits in industrial electrical installations. As part of the proven ABB S300P series, it is designed for demanding applications requiring exceptional breaking capacity and reliable circuit protection.
Manufactured in accordance with international IEC and UL standards, the S303P-Z6 delivers outstanding electrical performance while ensuring maximum safety for industrial switchgear, distribution boards and control panels. Its compact DIN rail design, integrated trip indicator and compatibility with ABB System pro M Compact accessories make installation and maintenance straightforward.
With a 6 A current rating, a Type Z tripping characteristic and a 100 kA ultimate short-circuit breaking capacity, the S303P-Z6 is ideal for protecting highly sensitive electrical and electronic circuits where rapid fault disconnection is essential.
The ABB S303P-Z6 miniature circuit breaker automatically disconnects electrical circuits when overload or short-circuit conditions occur, helping protect sensitive electrical equipment, minimise downtime and improve operational safety.
Its Type Z tripping characteristic provides rapid operation at relatively low fault currents, making it particularly suitable for protecting electronic equipment, instrumentation, semiconductor devices and control circuits that require fast fault protection.
