ABB S202-C40 two-pole miniature circuit breaker with a 40 A rated current, C curve tripping characteristic and 6 kA rated breaking capacity for overload and short-circuit protection.
£55.79
The ABB S202-C40 is a dependable two-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 provides current-limiting protection for residential, commercial and industrial electrical distribution systems.
The S202-C40 uses two complementary tripping mechanisms. A delayed thermal mechanism responds to sustained overloads, while an electromagnetic mechanism provides rapid disconnection during short-circuit conditions. This helps protect cables, switchgear and connected equipment from damaging overcurrents.
With a 40 A rated current, C curve tripping characteristic, two-pole configuration and 6 kA rated breaking capacity, the ABB S202-C40 is suitable for correctly designed circuits with moderate inrush currents. Typical uses include commercial distribution boards, HVAC equipment, pumps, motors, industrial control panels and general-purpose power distribution.
The ABB S202-C40 automatically disconnects a circuit when an overload or short circuit occurs. Its thermal trip responds to prolonged overcurrent, while the electromagnetic trip rapidly interrupts high fault currents to help minimise damage to electrical wiring and connected equipment.
The C curve characteristic provides tolerance for moderate temporary inrush currents while maintaining effective fault protection. This makes the S202-C40 suitable for circuits supplying HVAC systems, pumps, motors, commercial equipment and industrial machinery, provided the breaker rating and cable size have been selected by a qualified electrical professional.
