KXQ3 series dual power automatic transfer switch (PC)

◎Application:

KXQ3 dual power automatic transfer switch apparatus, apply to dual power supply system(PC) of rated voltage 400V, 50Hz, rated current till 3200A. Widely used in level one load and one part level 2 load. While commonly used power have fault or electricity cutoff, standby power can be used in extreme short time, also can be used for infrequence connecting and breaking circuit isolating, but don't have overload protection and short circuit protection function.

◎Model No. and meaning:  

◎Summarization

KXQ3 automatic transfer switch apparatus combine switch and logic controller, combine electric and mechanical together, have voltage testing, frequency testing, communication interface, interlock of electric lock mechanical etc functions, can realize automatic, electric remote and emergency manual control. Operation according to logic order, fast circuit transferring, realize safe isolating, greatly improved electric safety performance.

KXQ3 transfer switch apparatus integration design, compact appearance. Control part use metal shell, switch shell is made of glass fiber unsaturation polyester resin, good dielectric performance, high protection ability and operation high safety. Integration shape beauty, novelty, compact, small volume, complete function.

◎Performance and features:

◆Adopt dual composite type contact, horizontal pull structure, micro computer pre-storage and micro computer control technology, basically realize no arc(without arc cover.)

◆Adopt reliable mechanical interlock and electric interlock, perform component use independent load isolating switch, safe and reliable to operate.

◆Can be forced to zero in emergency condition(cutoff dual power simultaneously), to satisfy fire fighting integration requirement.

◆Perform load isolating switch transfer use single electric motor drive, reliable and stable to transfer, low noise, little impact force.

◆operator drive motor have instantaneous current through only at transferring perform load isolating switch, no need providing working current when working steady, remarkable at saving energy.

◆Perform load isolating switch have mechanism interlock device, ensure commonly used power and standby power working reliably.

◆Have obvious switch on/off position indicating and padlock function, reliable to isolate power and load

◆High safety, high automation, high reliability, working life reach more than 8000 times

◆Integration design, accurate, flexible and smooth switch transferring, adopt advantage international logic control technology, high anti-interference ability, no interference to surrounding

◆Have 3 working status: main commonly used power on, standby power off; main commonly used power off, standby power on; main commonly used power off, standby power off;

◆easy installation, control circuit use plug type terminal to connect

◆Four operation function: emergency manual operation, electric remote control operation, emergency cutoff operation at automatic control status, automatic operation
