Product Description

VS1 high voltage vacuum circuit breaker,is a three-phase AC 50Hz,rated voltage of 12kv switchgear.

Shunt release
Shunt release can realize the remote control to break the circuit breaker.
Accessories of YCW3
Motor-driven energy-storage mechanism
With the function of motor-driven storing and auto restoring energy after closing the
circuit breaker, the mechanism can ensure closing the circuit breaker instantly after
breaking the circuit breaker.
rated control power voltage Us(V) AC220V/230V,AC380V/400V,DC220V,DC110V
work voltage (0.85~1.1)Us
power loss 75W(1600A), 85W(2000A),110W(3200A,4000A),150W(6300A)
energy-storage time <5s
rated control power voltage Us(V) AC220V/230V, AC380V/400V, DC220V, DC110V
work voltage (0.7~1.1)Us
breaking time (50±10)ms
Forbid making the power for long time to avoid the shunt release being damaged.
Closing electromagnet
After the motor finishing the energy storage, closing release can instantly close the
circuit breaker.
rated control power voltage Us(V) AC220V/230V, AC380V/400V, DC220V, DC110V
work voltage (0.85~1.1)Us
closing time (55±10)ms
Forbid making the power for long time to avoid the closing release being damaged.
Under-voltage release
Without power supply, under-voltage release can't close.
It is classified into instantaneous and time-delay type.
After closing the circuit breaker, under-voltage release can break the circuit breaker
when the voltage drops to (70%~35%) Us. The circuit breaker can be closed again
when power voltage recovers and exceeds 85%Us.
rated control power voltage Us(V) AC220V/230V,AC380V/400V
action voltage (0.35~0.7)Us
reliable making voltage (0.85~1.1)Us
reliable non-making voltage ≤0.35Us
delay time: 0.5s,1s,1.5s,3s (YCW3-1600 , non-adjustable);
0.5s, 1s, 3s, 5s(YCW3-2000A, 3200A, 4000A, 6300A, adjustable).
Make sure there is power supply on the under-voltage release, before making the
circuit breaker.
