ABB S204D63 four-pole miniature circuit breaker with a 63 A rating, D-curve tripping characteristic and 6 kA short-circuit capacity for industrial and commercial circuit protection.
£259.76
The ABB S204D63, also identified as S204-D63, is a premium four-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits. As part of the trusted ABB System pro M compact S200 series, it is suitable for demanding residential, commercial and industrial electrical installations.
The breaker combines a delayed thermal tripping mechanism for overload protection with an electromechanical tripping mechanism for rapid short-circuit interruption. Its D-curve tripping characteristic is specifically intended for circuits with high inrush currents, including motors, transformers, compressors, pumps, welding equipment and other inductive loads.
With a rated current of 63 A, a four-pole configuration and a rated short-circuit capacity of 6 kA at 230/400 V AC, the S204D63 delivers reliable protection for three-phase installations requiring simultaneous switching of all four conductors. Its compact modular construction allows quick installation on a standard 35 mm DIN rail within distribution boards and industrial control panels.
The ABB S204D63 automatically disconnects electrical circuits whenever overload or short-circuit conditions occur, protecting cables, connected equipment and personnel. Its current-limiting construction helps minimise fault energy and contributes to improved installation safety.
Its D-curve characteristic makes it particularly suitable for motors, transformers, compressors, welding equipment and other inductive loads where high temporary starting currents are expected without causing nuisance tripping.
