a) In Thyristor since there are no mechanical movements of contacts involved, no arcing and sparking takes place and no audible switching noise is produced.)

b) Due to zero cross over switching techniques, voltage transients can be controlled within the safe limits.

c) Using VTSM it is possible to switch the capacitors faster than 1000mS rate, Whereas, contactors cannot be switched that fast.

d) There are no limitations in number of switching operations for thyristor compared to contactor.

e) These VTSM modules are safe to operate under the environment of maximum 70oC @ 90% RH - non-condensing.

1.zero cross switching 
Its methods to realize the current zero- cross cut off are that at the time of switching off , the thyristor conducts the zero-cross triggering operation at first at the minute of voltage zero cross .after stabilize  the magnetic latching relay attracts and conducts and in switch off ,the magnetic latching relay is cut out first . then the thyristor conducts the time delay zero-cross switch off operation . in order to realize the current zero-cross cut off operation.
2.voltage phase failure protection 
When the system voltage is supplied under phase failure .the switch refuses the closing operation ,after the system is switched on ,if the phase failure happens again .the system refuses the switching on operation automatic
3.under voltage protection 
When the voltage is 20% of rated voltage or less than (220v) the switch refuse the close operation .and it will protect by itself .the system automatically monitors the operation state of thyristor and magnetic latching relay , if the system has the trouble ,it refuse the making operation and exits from the switch on operation or conducts the breaking operation 
4.power failure protection 
After switching on if the power is cut off immediately ,it will trip and switch off automatically 
5.no harmonic wave making  
At the time of conduction ,the thyristor conducts the zero cross triggering operation ,after delaying relay attracts and conducts ,therefore the attraction and conduction of relay can't produce the harmonic wave 
6.low power consumption 
Due to using the magnetic latching relay ,the control device consumes the power only at the moment of switching operation ,usually it can't cause any power consumption ,and due to the small contact resistance of magnetic latching relay , it can't produce the heat ,thus it is unnecessary to equip the radiator of fan , to reduce the cost and thoroughly avoid burning the Thyristor and damaging other electric appliances running with the system .as as to achieve the aim of saving energy and lowering the consumption 
7.photoelectric isolation between the input signal and compound switch 
Strong interference resistance and reliable and safety operation ,the products adopt the advanced intelligent control technology and the latest electronic elements ,compared with the similar products ,It has ultra high performance in the respect of inrush current and reliability
