110V 63A Manual Transfer Switch

110V 63A Manual Transfer Switch interlocking circuit breaker is a new type of circuit breaker with an interlocking mechanism independently developed by our company. This product adds an interlocking function based on the original small circuit breaker, that is, when one side of the circuit breaker is closed, the other One side of the circuit breaker can only remain disconnected to achieve.

Line switching and other protection functions

The manual dual power switch independently developed by our company has dual functions of overload circuit protection and line switching. The product is reasonably designed, reliable, and beautiful in appearance5. It is mainly used for switching and other control circuit overload and circuit protection functions. TXB7SD manual dual power supply.

Switch products comply with GB10963 and IEC60898 standards.

Operating rules for dual power conversion switches (30 amp manual transfer switch)

1. When the power outage, and in a short period of time can not restore power supply, must enable the standby power supply.

Step:

The removal of electric power supply of each circuit breaker (including the circuit breaker control cabinet, power distribution room dual power switch box power supply breaker), open the double throw switch to the prevention of back power supply side, keep the double power supply switching power supply box self breaker is in off state.

Start the standby power supply (diesel generator set), when the standby group is running normally, turn off the generator air switch and the circuit breaker in the control cabinet.

The power supply circuit breaker of each power supply is switched off by the power supply switch box.

During the operation of standby power supply, the operator on duty shall not leave the generator set, and adjust the voltage and the frequency of the plant in time according to the change of the load.

2. The electric supply restore power supply, should do a good job in a timely manner to power conversion, cut off the standby power supply, restore power supply.

Step:

The sequentially disconnect power supply of each circuit breaker, the order is: dual power supply switching power supply circuit breaker box, power distribution cabinet, each circuit breaker switch, the generator double throw switch to electric power supply side.

According to the diesel engine shutdown step down.

According to the order, the main switch of the power supply of the city is connected to each branch switch to close the circuit breakers one by one.

3. Check the instrument and indicator light is normal, start the transformer cooling fan.
