Why Choose the ABB S804C-C40 High Performance MCB?
The ABB S804C-C40 is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800C high-performance circuit breaker series, it combines a rated current of 40 A, C tripping characteristic and a high 25 kA breaking capacity for commercial and industrial installations.
This current-limiting circuit breaker incorporates thermal and electromagnetic tripping mechanisms. The thermal release protects against sustained overload conditions, while the electromagnetic release responds rapidly to short-circuit faults. Fast interruption and current-limiting operation help reduce the thermal and mechanical stresses imposed on conductors and connected equipment during severe fault conditions.
With four protected poles, a 40 A rated current and Type C characteristic, the S804C-C40 is well suited to multipole circuits with moderate switching or starting currents. Its high interruption capability and four-pole configuration make it a robust choice for three-phase plus neutral distribution, industrial control panels and other demanding electrical installations.
