The ABB ST204M‑D10 (often referred to by catalogue type SH204‑D10) is a 4‑pole miniature circuit breaker (MCB) from ABB’s S‑200 / System Pro M Compact series, designed for low‑voltage electrical protection. It provides reliable overload and short‑circuit protection for distribution circuits in residential, commercial, and light industrial installations. This compact DIN‑rail mountable breaker uses a D‑type trip characteristic, offering good tolerance for high inrush currents such as those from motors or transformers while still offering responsive circuit protection
