TJC-12/630 Ceramic vacuum arc extinguishing chamberDetailed product description：

Overview
The arc extinguishing chamber adopts corrugated ceramic as the insulation shell, and the contacts are made of copper tungsten carbide alloy material. It adopts advanced one-time sealing and discharging technology, which has the advantages of small volume, high insulation level, low current cutoff value, long service life, simple maintenance, no explosion hazard, no pollution, and low noise. The contactor assembled with it can frequently operate various electrical equipment, and when combined with fuses, it can form an F-C cabinet. Product Description
