Application

SUQ2 Micro-Breaking Dual Power Transfer Switch (here in after referred to as transfer switch) is suitable for AC 50/60Hz dual power supoly system with rated operating voltage of 400V amd rated operating current form 16~63A.Optional transfer of dual power can be made according to requirement. The product owns short circuit, overload, under voltage and loss-of-voltage protection function, as well as fire protection, double-break and output ON signal function. It's especially suitable for lighting circuit of office building, mall, bank, bus station and high-rise building requiring fire product complies with GB/T14048.11 standard.

Working Conditions

■The ambient temperature shall not be higher than +40℃, or lower than -5℃, and the daily average shall not exceed+35℃。

■The altitude of installation site shall not exceed 2000m.

■Relative humidity shall not exceed 50% at the ambient temperature of +40℃ ， a higher humidity is allowable at a lower temperature，the average maxinmum relative is 90% in the wattest month at a monthly average minimum teperature of +25℃，and special measures shall be taken for the condensation on surface of product due to temperature change

■Pollution calss：class III.

■In place of no intense vibration and impact，no harmful gas corrosive and disruptive to the insulation， no sever dust，no conducting microparticle and explosive substance，no high electromagnetic interference。

Product Featurres

■Reasonable structure, small volume, nice appearance, with provided with protective shield, safer and more reliable power supply.

■Complete protective fun ctions, including short circuit, overload, open phase and loss-of-voltage protection.

■Reliable remote double-break with EPS fire protectin power supply interface DC12-24V

■Noiseless, energy saving, simple installation, easy operation, raliable and stable performance.

Product Performance

■The transfer switch is composed of two Micro-Breaking and motor and mechanical rotating divice, and make detection to dual power through controller, when abnormality controller, when abnormality occurs to the circuit, the controller will make a logic judgment for the detection result and drive the operating mechanism to switch on or off according to according to command of controller, ensuring safe and reliable and stable performance.

■Rated short circuit breaking capacity:3kA 

■Rated short circuit making capacity:3kA 

■transfer time:≤3S 

■Control voltage of transfer switch: AC230V

■Mechanical life of transfer switch(transfer from normal to reverse power and return as one time):5000 times.

■Rated insulation voltage:U=500V

■Rated working current:10A,16A,20A,32A,40A,50A,63A

■The transfer switch has auto throw-in self-restoring fun ction with the normal supply operating preferentially in common condition, the user shall negotiate with the manufacturer during order placing for any other special requirement such as transfer switch of auto throw-in nonself-restoring mode.

Specifications

Installation

The inlet and outlet line & neutral line of normal and ready power shall be properly wired according to actual requirement of circuit desige. The outlet terminals of the two circuit breaker shall be connected in parallel with accordant phase order(refer to the wiring diagram).

As for 3P circuit breaker, the neutral line must be connected to the terminal of neutral line(the normal and reserve neutral line as shown in the fig.2 Shall be respectively connected to NO.1 and 2 connection terminal).

3. When manual operation is required for the transfer switch, button switch shall be put to manual position first, then transfer to normal or reseve power can be made by turing the button. When the control mode is in automatic position, the transfer will enter automatic work condition and the normal power will operate preferentially.

4. When the transfer switch is wired according to wiring diagram, after power on, if the normal and reserve power are in good condition, the indicator(red) of normal or reserve power will be on and the transfer switch will work normally.
