ČýĄ˘Features of ATS switch
Reliable mechanical interlock: The unique eccentric selective structure makes
sure one power supply to work and there is any possibility of two power sources
connecting the load at the same time.
Excellent arc extinction: all kinds of abnormal arc can be extinguished safely,
and the electric arc lasts for short time with less wear of the contact.
Multiple-piece main arcing contact: increasing the contact terminalĄŻs area of surface in
contact and contact pressure. The superheat and welding wonĄŻt happen; the life of
contact can be prolonged.
Rapid switchover: it can switch rapidly between main power and standby pow
er and the switching-time delay of ATS equipped with controller can be set by users.
Simple structure and small size: stable running, low breakdown rate, convenient
installation, usage and maintenance. Slow operation by rotating the handle while
maintaining in order to check and eliminate malfunction.
HZQ5 ATS belongs to PC type. Its cubage is smaller than that of CB type, but its
ampere rating is more than that of PC type.
Neutral pointĄŻs position: HZQ53 three-step switch can switch over in switch-on regime and stay momently in the neutral point so that it is convenient for users
to overhaul the load circuit(residence time shouldnĄŻt exceed several minutes.) HZQ52
two-step type couldnĄŻt stay in the neutral point.
Multifunctional controller: Liquid crystal display and digital dynamic supervisory control
display supply voltage and current, and control the transfer switch to finish switchover
as required among main power, standby power and neutral point under the
circumstance of over-voltage, over low voltage, loss-of-voltage, and non-full-phase.
ËÄĄ˘product model and meaning
1Ą˘The model and meaning of products are as follows:
1Ą˘HZQ52 is two-step automatic transfer switch. When receiving the change-over signal, the switch wonĄŻt stop in the middle splitting point and transfer rapidly
from one power to another power and its ampere rating is only 20A-500A.
HZQ53 is three-step automatic transfer switch. It can transfer instantly (or after a predetermined
time delay) from one power to anther power after receiving the change-over signal. It can also transfer to the middle splitting point disconnected with
other power supplies. Its ampere rating is 20A-5000A.
2Ą˘HZQ5 series of switches is PC type.
3Ą˘Other electric switches of other standards belong to special supply such as rated
operational current is 660v/690v, DC is 125v/250v; control voltage is 380v/400v/
100v270v; DC is 125v/250v and so on. Users
4Ą˘should specify when ordering.
5Ą˘The switches below 500A should be generally connected in front and the switches
above 630A should be connected at back. The others belongs be special supply.
