£105.08
The ABB S302P-B50 (Product ID: 2CDS382001R0505) is a premium 2-pole miniature circuit breaker (MCB) engineered to provide reliable protection against overloads and short circuits in industrial and commercial electrical installations. As part of the trusted ABB System pro M compact S300P series, it combines high performance, robust construction and dependable long-term operation.
Featuring a Type B tripping characteristic, the S302P-B50 is designed for circuits with low inrush currents, making it ideal for resistive loads, lighting circuits, socket outlets, control circuits and commercial electrical distribution where fast fault disconnection is required.
With a rated current of 50 A, a 2-pole configuration and an ultimate short-circuit breaking capacity of 25 kA, the ABB S302P-B50 provides dependable protection for industrial control panels, commercial switchboards and electrical distribution systems.
The ABB S302P-B50 automatically disconnects electrical circuits during overload or short-circuit conditions, helping to protect cables, connected equipment and electrical infrastructure while improving operational safety and minimising downtime.
Its Type B tripping characteristic provides rapid disconnection at relatively low fault currents, making it particularly suitable for resistive loads, lighting installations, office equipment, commercial distribution systems and control circuits.
