It also carries ratings under IEC/EN 60947-2 (15 kA Icu at 400 V AC) and UL 1077 recognition, making it suitable for both residential and industrial panel builds where a compact 4-module footprint is needed. The 10 kA rated short-circuit capacity (Icn) per IEC 60898-1 tells you the breaker can safely interrupt a fault up to that level; the higher 15 kA Icu (400 V AC) per IEC 60947-2 gives additional headroom for industrial applications where fault currents may be higher. The 20 kA rated conditional short-circuit current (Inc) at 400 V applies when the breaker is backed by an upstream device with a let-through current limit — coordination matters here. Rated operational voltage covers 400/440 V AC three-phase and 125 V DC, so it works in standard 400 V panels and DC control circuits. The dielectric test voltage of 2 kV for 1 minute confirms insulation integrity for 400 V class systems. As a miniature circuit breaker, the S204M-C50 protects wiring and loads against overcurrent and short circuits in final distribution circuits. The 4-pole configuration is standard for three-phase plus neutral systems, common in European-style panelboards and industrial control panels. The 50 A rating suits larger sub-feeds or high-load equipment like air handling units or process machinery.","metaTitle":"ABB S204M-C50 Miniature Circuit Breaker, 4-Pole, 50 A, 10 kA","metaDescription":"ABB S204M-C50 4-pole miniature circuit breaker, 50 A rated current, 10 kA breaking capacity per IEC/EN 60898-1.
