The ABB 2CDS214001R0251 is a 25A, 4-pole, C-curve Miniature Circuit Breaker (MCB) from the ABB S200 Series (System PRO M). This MCB is designed for applications requiring the simultaneous interruption of all phase conductors and the neutral conductor in three-phase electrical systems. It provides comprehensive overload and short-circuit protection for circuits and cables in commercial, industrial, and large residential installations. The "C" tripping characteristic makes it suitable for protecting circuits with moderate inrush currents. Its primary use is in 3-phase + Neutral (TN-S, TN-C-S) or 3-phase distribution systems where complete isolation or protection of the neutral is required by regulation or design.
