Description
ZN63 (VS1) AC vacuum circuit breaker circuit board is used in circuit breaker operation and control circuits. There are two specifications. One of them is when the power supply is AC power supply, which rectifies the AC current into DC current, supplies the operating circuit breaker, and closes the circuit breaker. gate coil loop and provide DC power for other loops.
The other is the case of DC loop power supply, the rectifier bridge is cancelled on the circuit board, the connection between the two terminals is connected, and the circuit board is used to connect the circuit. The circuit board is also equipped with a miniaturized DC anti-jump relay, which can be directly connected to the control circuit.
The circuit board is mounted in two ways, one is a galvanised iron plate pillar type and the other is an injection moulded mounting box.
There are two types of ZN63(VS1) AC vacuum circuit breaker circuit boards
A. AC 220V supply circuit board, type: ZN63 [VS1] circuit board, SLB-1
B. DC 220V supply circuit board, type: ZN63 [VS1] circuit board, SLB-2
