Why Choose the ABB S403P-C16NP Miniature Circuit Breaker?
The ABB S403P-C16NP 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-C16NP features a Type C tripping characteristic and a rated current of 16 A. A delayed thermal tripping mechanism provides overload protection, while an electromechanical tripping mechanism provides rapid protection against short-circuit faults, making the breaker suitable for circuits that can experience moderate inrush currents.
With a 3P+NP configuration, four protected poles and a rated ultimate short-circuit breaking capacity of 40 kA at 230/400 V AC according to IEC/EN 60947-2, the S403P-C16NP provides robust protection for three-phase plus neutral circuits where high fault-current capability and convenient SMISSLINE TP plug-in installation are required.
