Application:

NQ3 series  dual  power  automatic transfer  switches  (follow brief  as  setting)  is  one of  adopted international technology developed by our company. The setting is suits for AC 50Hz, rated working voltage is 400V, rated current 6A-100A and under dual power supply system. It has over voltage, under voltage, lost phases protection function. The setting mainly used for hospital, shopping center, bank, and chemical industry, metallurgy, high building, military facilities.

Features:

Small volume, high breaking, short arcing and compact structure«Complete protection function, with short voltage, over voltage, phase faulty and under voltage etc protection.«Communicate with EPS fire control power, DC24V can remote separate steably.«No noisy, save on energy and mounting conveniently

Performance:

Transfer switch is composed with 2 sets MM5-63 MCB and motor mechanism rotating device, through circuit breakers to inspect the two way power. When the circuit abnormal, the controller will make a logic determine with the inspect result. According controller order to drive the operate mechanism on or off, thereby supply electric security and steablity.«Connection and breaking capacity

Rated short connecting capacity:3kATransfer time:3sThe control voltage of transfer switch:AC230VThe mechanism life of transfer switch:3000 times;electric life:1500 timesRated insulate voltage:Ui=500VRated working current:10A,16A,20A,25A,32A,40A,63AUnder normal conditions, the transfer switch has self operation and self recovery function, and normal power first. If need self operation and self recovery function transfer switch in special occasion, the user should consult with the manufacture.:3kA
