KYN61-40.5 Indoor Armored Metal-Enclosed Switch Equipment

KYN61-40.5 Indoor Armored Metal-Enclosed Switch Equipment has many Advantage:

1.Perfect structure: the cabinet is fully assembled, multiple folding process structure of aluminium zinc dressing plate;

2.Extremely safe: the cabinet is divided into four independent compartments as a whole, which is safe and reasonable;

3.Convenient and simple maintenance: the cabinet with floor-standing VTZ-40.5 handcart circuit breaker, easy to overhaul and maintain;

4.Complete five defence interlock:

a.The handcart can be moved from the test/isolating position to the operating position when the circuit-breaker and the earthing switch are in the open position. Reverse movement is also possible in this tripping condition (mechanical interlocking).

b.The circuit breaker can only be closed (mechanically and electrically interlocked) when the handcart is already fully in the test or operating position.

c.When the handcart is in the running position, the control wire plug is locked and cannot be unplugged.

d.The earth switch can only be closed when the handcart is in the test/isolation position or removed (mechanical interlocking).

e.The handcart cannot be moved from the test/isolation position to the operating position when the earth switch is closed (mechanical interlock).

f.Additional interlocking devices, such as latching solenoids, can be fitted to the trolley and/or earth switch actuator.

5.Large scope of application: the series of products cover a wide range, from rated current 630A to rated current 3150A, from rated breaking current 20KA to 31.5kA comprehensive coverage; covering -40℃~40℃ use of the environment; cabinet circuit breaker can be equipped with domestic and foreign trolley-type vacuum circuit breakers.
