Product Details

Full automatic transfer switch  MCB Air Circuit Breakers 3P / 4P  ATS

 

APPLICATION

GNQ1series molded case circuit breaker intelligent dual-power automatic transfer switch, brief namely transfer switch, is the latest developed new products, suitable to power system of AC 50/60Hz,rated voltage 400V,rated current 6-800Amp.When the normal power have fault, the transfer switch can automatically switch between normal power and backup power or generator to make sure of the power reliable and safe. It is also possible to selectively switch between two power according to the load. The transfer switch has the protections of over load, under voltage, short circuit, phase loss etc. and mainly applied at the places like fire control, airport ,television station, hospital, shopping mall ,bank , chemical engineering ,metallurgy, high building and military facility etc. where the power can not be interrupted to make sure of the continuous power.

 

WORKING CONDITIONS

The around air temperature should be between +5℃ and +40℃ ,the average value should be not higher than 35℃;

 

The sea level should not exceed 2,000m;

 

The air relative humidity should not exceed 50%,lower temperature ,the humidity can be higher, the average temperature +25℃,,the max relative humidity should not exceed 90% and the surface condensation should be taken into consideration cause of the temperature change;

Pollution degree III;

The working place is without strong vibration and impact, no corrosive gas that corrode metal and break the insulation, no strong dust, no conductive particulate and explosive dangerous substance, no strong electromagnetic interference.

 

PRODUCT STRUCTURE AND FEATURES

GNQ1 intelligent double power automatic transfer switch is composed of two sets 3 pole or 4 pole molded case circuit breaker and auxiliary parts alarming contact, mechanical interlock transmission mechanism ,controller etc. It has the features of

 

Adopt high performance SCM control program , nixie tube voltage display; Anti-interference strong and accuracy high;

With protections of over load, under voltage, short circuit ,phase loss, intelligent alarm;

Transfer switch adjustable ,transferring time accurate;

Small volume ,breaking capacity high ,flash-over short, structure compact , appearance elegant;

Anti-corrosion strong, power supply reliable;

Operation without noise, energy saving and power loss decreased, installation convenient ,operation easy, stability high.

With reliable mechanical and electric interlock protection device preventing the two mccb from closing at the same time;

Automatic transferring parameter can be set outside; With operation motor intelligent protection;

The ats with fire control circuit, when the fire control center send a control signal to the intelligent controller, both the two mccb will be broken automatically;

With generator starting signal, when the normal power is abnormal, ATS controller will send a starting signal to the generator, then it will generate automatically.
