Product Details
Product Description
OverviewZW20 smart outdoor VCB adopts advanced electronic sensors and digital technology, which can be used in urban and rural power distribution system as the protection of breaking and closing load current, overload current and short circuit current. It can be used with feeder automation terminal to realize feeder automation and distribution network automation, and support multiple communication modes and protocols. The circuit breaker has built-in capacitor energy taking device, so it does not need additional power supply voltage. Main features
1.full set of type tests
2.Be made of hydrophobic epoxy resin,safe and environmentally friendly
3.High reliability vacuuminterrupter
4.Manual or electric spring operating mechanism, long electrical and mechanical life
5.Electronic current/voltage transformers with high accuracy
6.Digital signal transmission anti-jamming
7.Can be used as recloser, segmenter
8.three-stage current protection and multiple feeder automation modes
9.Strong sealing, reliable operation in humid, high cold, high dry heat, high pollution and other environments
10.E2、M2、C2 outdoor vacuum circuit breaker
