ATS Automatic Transfer Switches

EATS4 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.
 This ATS automatic transfer switch is mainly made up of power transfer actuating breaker (including normal power actuating breaker QN and reserve power actuating breaker QR, one for each) automatic controller, electric operating mechanism and so on. Wherein, the circuit breaker QN and QR retains the original over-current protection and short-circuit protection.
