Product Description
IntroductionZW27F-12 series AC high voltage demarcation vacuum circuit breaker(watchdog) is the distribution equipment for the rated voltage 12KV, AC 50Hz circuit.
Installed in the duty demarcation place of overhead distribution nets, front of users' inlet wire.
Can automatically switch-off failure of single-phase wiring to ground and short-circuit between phases.
Avoid the failure affecting the distribution net to ensure electrical security of normal users.
Features1. Automatically lock short-circuit between phases
When Short-circuit between phases happens in the Users‘ branch lines, demarcation circuit breaker acts before substations protection, instant breaking and locking.
2. Automatically switch-off failure of single-phase wiring ground
When single phase wiring ground failure happens in the Users' branch lines, demarcation circuit breaker automatically breaks before substations protection.
3. Fast location the error point
4. Circuit breaker function
