Disconnector
Explanation:
The RGW1-24 outdoor AC fuse switch combination circuit breaker is a new product designed and manufactured using the existing mature production experience of circuit breaker switches and advanced fuse protection technology in China. The fuse switch combination circuit breaker consists of a breaking plate, HRC fuse, and operating mechanism, which has the advantages of strong arc extinguishing ability, reliable performance, long service life, small size, no explosion hazard, and no pollution to the environment
RGW1-24 outdoor AC fuse switch combination circuit breaker is suitable for 24kV power systems with voltage and no load
It complies with IEC62271-12; GB/T3814: 3.6~41.5kV High Voltage Switches, IEC61694； GB/T11122: High voltage switchgear and control gear
