Overview
The VOE3-63 is a miniature circuit breaker for overload and short-circuit protection in AC 50/60 Hz electrical circuits. It is available with rated currents from 6 A to 63 A, C or D tripping curves, and 1P, 2P, 3P or 4P configurations. Single-pole versions are rated at 230 V AC, while 2P, 3P and 4P versions are rated at 400 V AC. Designed for DIN-rail mounting, the breaker is intended for residential, commercial and industrial power distribution systems. It can also provide infrequent circuit switching under normal operating conditions.
