Product overview

VS1-Series circuit breakers are complete independently developed by Knkong based on the advanced design concept; it adopts a modularized mechanism, which is easy for installation, maintenance, testing, and operation. As compared with conventional VS1 circuit breaker. it features higher operation stability, higher safety, and extended service life. The product can satisfy customers demand application in 12kv and 24kV power transmission and distribution systems, which is extensively applied in such industries as power, energy, petrochemical engineering, metallurgy, manufacture, traffic, building, and environmental protection as well as large-scale enterprises and national key projects

Technical Parameters

Operation safety

With anti-maloperation locking protection these circuit breakers, working in switchgear cabinets, can realize "five-protection" interlocking functions, avoiding malapert and maximizing the protection of an operator's personal safety.

Only when the circuit breaker and earthing switch are in the disconnected position can the truck of circuit breaker be racked to the service position from the test position

The circuit breaker can be closed only when in the service/test position.

With the circuit breaker closed its truck cannot be racked in or racked out which can be realized only when the circuit breaker is in the disconnected position.

The circuit breaker in a closed position cannot be racked out from the service position to the test position.

The circuit breaker cannot be closed while it is being racked in.

When the circuit breaker is closed, if the closing signal fails to be removed timely, the internal anti-trip control circuit will cut off the closing circuit to prevent multiple reclosing (optional).

If the electric closing lockout is selected, the circuit breaker will be unable to be closed when the secondary circuit fails to provide power or the power provided fails to meet the normal operation of the locking electromagnet(optional).
