1. Under the following conditions, the neutral conductor should have the same cross-section as the phase conductor: 1) Single-phase two-wire circuit of any cross section; 2) In three-phase four-wire and single-phase three-wire circuits, the cross-section of the phase conductor shall not exceed 16mm2 (copper) or 25mm2 (aluminum). 2. In a ... Read More

The solid-sealed pole is to embed the vacuum interruptor and circuit-breaker related conductive parts into the easy-curing solid insulating material such as epoxy resin or thermoplastic material to form the pole at the same time. The pole of the circuit breaker becomes an integral part. The solid-sealed pole has the ... Read More

At present, the stroke of the moving iron core (that is, the air gap between the moving iron core and the yoke) of the permanent magnet mechanism (bistable) produced at home and abroad is relatively small (usually no more than 25mm), much smaller than the conventional electromagnetic, spring, hydraulic and ...
