Why Choose the ABB S403P-C6NP Miniature Circuit Breaker?
The ABB S403P-C6NP is a high-performance 3-pole plus protected neutral miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit currents. As part of the ABB SMISSLINE TP S400P series, it combines current-limiting circuit protection with ABB's plug-in technology for efficient installation in commercial, industrial and critical power distribution systems.
The S403P-C6NP features a Type C tripping characteristic and a rated current of 6 A, making it suitable for low-current circuits that can experience moderate inrush currents. A delayed thermal tripping mechanism provides overload protection, while an electromechanical tripping mechanism provides rapid protection against short-circuit faults.
With a 3P+NP configuration, a rated current of 6 A and a rated ultimate short-circuit breaking capacity of 40 kA at 240/415 V AC, the S403P-C6NP provides robust protection for three-phase plus neutral circuits where high fault-current capability and convenient SMISSLINE TP plug-in installation are required.
