Why Choose the ABB S403M-C40 Miniature Circuit Breaker?
The ABB S403M-C40 is a current-limiting three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for three-phase electrical circuits. As part of the ABB SMISSLINE TP S400M series, it combines dependable circuit protection with a plug-in design developed specifically for the SMISSLINE TP distribution system.
Rated at 40 A with a Type C tripping characteristic, the S403M-C40 is suitable for commercial and industrial circuits where moderate starting or inrush currents may occur. It incorporates a delayed thermal tripping mechanism for overload protection together with an electromechanical tripping mechanism for rapid short-circuit protection.
With a rated operational voltage of 230 / 400 V AC and a rated short-circuit capacity of 10 kA, the S403M-C40 provides robust protection for three-phase distribution, machinery and equipment circuits. Its three-pole plug-in construction enables efficient integration into compatible ABB SMISSLINE TP assemblies.
