Why Choose the ABB S401P-B63 Miniature Circuit Breaker?
The ABB S401P-B63 is a high-performance 1-pole miniature circuit breaker (MCB) designed to protect cables and conductors against overload and short-circuit currents in commercial and industrial electrical distribution systems. Part of the ABB S400P range for the SMISSLINE TP plug-in system, it combines dependable circuit protection with direct plug-in connection to compatible SMISSLINE TP socket systems.
The S401P-B63 uses thermal overload protection together with electromagnetic short-circuit protection. Its Type B tripping characteristic is suited to circuits with relatively low starting and inrush currents, while the single-pole construction provides compact protection for compatible branch and distribution circuits.
With a rated current of 63 A, a 1-pole configuration and a rated ultimate short-circuit breaking capacity of 20 kA, the S401P-B63 provides robust protection in a compact format. ABB order code 2CCG000409R0001 identifies this specific 63 A Type B SMISSLINE TP circuit breaker.
