ZGQ1-63L Automatic Transfer Switches (ATS)

Rated current: 6A~63A
Poles: 3P 4P
Functions of ZGQ1-63L Automatic Transfer Switch CB-class:
The main power has over voltage protection functions;
No capacity of issuing signs to generate motors;
Auto / manual transfer options;
ZGQ1 series of Dual Power Automatic Transfer Switch consists of two 3-electrodeor 4-electrode micro-breakers and some other accessories (assistance, alarmingcontacts) such as mechanical interlocking setup and controllers and so on.
Characteristics of ZGQ1-63L Automatic Transfer Switches CB-class:
-Compact design with a simple structure, easy operation and a long life-span,3p or 4p is available;
-Switch conversion applies single motor drive, stable, no noise and with alittle wallop;
-Including mechanical and electrical interlocking, manual and automatictransfer are available with conversion reliabilities;
-Different rated currents of normal and backup breaker are allowable;
-There is a connection terminal in A.T.S for users to connect cables and it can also reflect the on/off status of the breaker.There are various instructions on A.T.S panels.
Working Principle of Automatic TransferSwitches CB-class
When the main power supply keeps normal and function keys are on automaticshift, the backup breaker opens and the normal breaker closes to ensure thelatter one connect the load. If one or three-phase of the normal power breaksvoltage, ATS will transfer the load from the normal circuit to the backupcircuit (while the backup circuit has a normal voltage)andreturn it to main circuit while main power supply recovers.
Operation and Maintenance of ZGQ1-63L Automatic Transfer Switches CB-class
Manual operation is always available no matter whether there’s a voltage innormal and backup power supply or not,while manualoperating, you should set manual/automatic key on manual position and push itin a clockwise direction to the terminal, then the backup power supply implementary breaker QR opens, and the main power supply implementary breaker QR closes: When pushing in acounterclockwise direction, the states of breakers will be totally reversed.The power indicating light of the panel represents the working power supply ofautomatic control box,ifit’s off, it means power supply of the control box goes wrong and should notadjust the switch. After the normal recovery, set manual/automatic key onautomatic position. Set automatic transfer switch on the circuit no matternormal or backup ones as long as it can keep main power supplying, the correspondinglights will be on. There are two 1Afuse breakers and a connection terminal in the automatic transfer switch andthe fuse breaker can be used as a automatic fusebreaker to protect short-circuit. The connection terminals used to distributecurrent that assist connecting the indicating lights on the control panels witha voltage of 220V and a current of 150mA, refer to the accompanied manual andcurrent chart for detailed operation information to connect.
Trouble-analysis and Exclusion ofAutomatic Transfer Switch CB-class:
When the supplied power changes under the automatic control status, theelectronic-operation organs don’t run just as the small breaker don’t close oropen, then you should first check:
1) Whether all circuits of one electric grid are power cut
2) Whether there are cables breaking off
3) Whether the fuse itself has been broken, if front terminals of any breakerare power on and with a correct connection and a good fuse but still couldn’tclose or open, you should invite the professional persons or contact themanufacture.
Order Notice
while ordering our ZGQ1-63 automatic transfer switch, you should note themodel, specifications, the model and series of equipped breakers. For example:to order an automatic transfer switch appliance, self-transfer andself-recovery type, rates current of 50A,4P, you can write it like this: ZGQ1-63/4P(50A).Please contact the manufacturing company forspecial requirements, and described in the order.
