ABB S202D4 2-pole 4 A miniature circuit breaker with a D curve tripping characteristic and 6 kA breaking capacity for overload and short-circuit protection.
£60.67
The ABB S202D4 is a reliable 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the established ABB System pro M compact S200 series, it combines thermal and electromagnetic tripping mechanisms to provide dependable protection for cables, equipment and connected loads.
Featuring a D curve tripping characteristic, the S202D4 is suitable for circuits that experience high temporary inrush currents during start-up. This makes it particularly useful for transformers, motors, solenoids, compressors and other inductive equipment that could cause nuisance tripping when used with a more sensitive circuit breaker.
With a rated current of 4 A, a 2-pole configuration and a rated operational voltage of 400 V AC, the ABB S202D4 provides compact and effective protection for industrial, commercial and specialist electrical installations. Its DIN rail format enables straightforward installation within distribution boards, control panels and machinery enclosures.
The ABB S202D4 automatically disconnects a circuit when excessive current is detected. Its delayed thermal mechanism responds to sustained overload conditions, while its electromagnetic mechanism provides rapid protection during short circuits.
The D curve characteristic permits higher temporary starting currents than B or C curve breakers, helping prevent unnecessary disconnection when energising equipment such as transformers and motors. This makes the S202D4 a practical choice for specialist control circuits and industrial equipment with demanding start-up characteristics.

The ABB S202D4 protects electrical circuits against overloads and short circuits, particularly circuits supplying equipment with high temporary starting currents.
The miniature circuit breaker has a rated current of 4 A.
A D curve circuit breaker permits relatively high temporary inrush currents before its instantaneous trip mechanism operates, making it suitable for transformers, motors, compressors and other inductive loads.
The ABB S202D4 has a 2-pole configuration, allowing two conductors to be protected and disconnected simultaneously.
The breaker is designed for mounting on a standard DIN rail inside electrical distribution boards, control panels and machinery enclosures.
ABB System pro M compact miniature circuit breakers are widely used by electrical contractors, machine builders and control-panel manufacturers for reliable circuit protection and consistent performance in demanding installations.
