The Siemens 5SN6332-8CP is a 3-pole miniature circuit breaker (MCB) from the SENTRON 5SN series, rated for 400 V AC at 50 Hz. It provides overcurrent protection with a breaking capacity of 6 kA according to EN 60898 and 15 kA according to IEC 60947-2 — the higher IEC figure means it can safely interrupt fault currents up to 15 kA in industrial panels where the prospective short-circuit current is higher than residential-grade 6 kA.
Accepts solid conductors up to 35 mm² at the terminals. The -40 to 75 °C ambient range covers unheated enclosures and hot panel interiors alike.
