ABB 2CDS254001R0504 S204-C50 4P 50A 6kA C-Curve DIN-Rail Miniature Circuit Breaker

The ABB S204-C50 miniature circuit breaker (MCB), SKU 2CDS254001R0504, is a 4-pole, 50A, 6kA breaking capacity device from the S200 series, designed for overcurrent and short-circuit protection in industrial and commercial control panels. Rated at 230/400V AC with a C-curve trip characteristic, the S204-C50 provides reliable protection for resistive and low-inductive loads, motors with moderate inrush, and distribution circuits. Compact DIN-rail mounting (70mm × 88mm × 69mm) makes it ideal for space-efficient panel builds.
