4p ATS Automatic Transfer Switch

ATS CB Class 250A 400A 4p Automatic Transfer Switch

 

 

SQ3-63 series automatic transfer switch is designed and developed by our company according to universal customers' requirements. This switch uses DZ47 miniature circuit breaker (improved type) as the actuating element, is equipped with the new type control mechanism. With the smallest volume among the similar products, it also has the functions like the fire control and power generation, and, it is specially used in the important power supply locations where the power failure is not allowed.

Normal working conditions

Ambient temperature: -5~+40ºC, and the average temperature in 24 hours below +35ºC(except for special orders).
Elevation of installation site: 2000m
Relative humidity: not exceeding 50% at the maximum ambient temperature of +40ºC.
With lower temperature, higher humidity would be permitted, but the lowest average temperature in a month not exceeding 90% in
that month, andgiving consideration to the dews on the goods surface, which would appear due to temperature change.
Pollution protection: 3 grade
The breaker should be put in the place where there isn't any explosive medium and conductive dust and no gas, which would
corrode metal or destroy theinsulation.

Structure and properties

SQ3 is a critical component of any emergency or standby power system. When thenormal (preferred) source of power is lost, a transfer switch quickly and safely shifts the load circuit from the normal source of power to the emergency (alternate) source of power. This permits critical loads to continue running with minimal or no outage. After the normal source of power has been restored, the re-transfer process returns the load circuit to the normal power source.

1) The setting is formed with two sets of power-operated operation mechanism circuit breakers and mechanical interlocking, fuse, wiring
terminal.
2) Two-set circuit breakers have electric interlocking and mechanical interlocking double protections to prevent the two-set circuit
breaker close on at the same time.
3) The setting suits for 220V working voltage (circuit breaker rated working voltage), control the power pass the case, frame board
control pushbutton (user self-prepared and connect to) direct control two sets power operated operation mechanism to carry out the power reliable switch over.
4) Suitable for general manual work control occasion, simple structure, low cost.
