Tổng quan
The VIOX VOB3-63 is a miniature circuit breaker designed to provide overload and short-circuit protection in AC 50/60 Hz electrical circuits. The series covers rated currents from 1 A to 63 A and is available with B, C and D tripping curves for resistive, general-purpose and high-inrush loads. Its 1P, 2P, 3P and 4P configurations support lighting, socket, control and equipment circuits in residential, commercial and light industrial distribution systems. The 18 mm modular design is intended for DIN-rail installation in distribution boards, consumer units and control panels.
