ZN3A 12KV high voltage permanent magnet vacuum switch
  Detailed introduction

1.Product descriptions

ZN3A series high voltage permanent magnet vacuum switch use the good quality circuit breaker switch tube,euipped with the advanced and reliable bistable permanent magnet mechanism and the intelligent controller,has the function of the tripping prevent,small closing/opening current and switch on when powerdown.Fast closing/opening speed,big clearance and travel distance,small bounce,stable synchronism and good breaking performance.

The insulation parts use epoxy resin casting,the frame use the metal structure,structure reasonable and beautiful.It is widely used in the load of the large capacity capacitor group.

2.The use of the environment conditions

2.1.Ambient temperature -25 ℃ ~ +40 ℃.

2.2.Installation site altitude does not exceed 2000m.

2.3.The relative humidity of the air,the wettest month average monthly maximum relative humidity of 90%,monthly average minimum temperature of 25°C,and taking into account the cream of temperature changes on the surface of the product.

2.4.Environment:anhydrous invasion,non-corrosive and flammable gas and excessive vibration occasions.

3.Use requirements

3.1.Properly select the the contactor technology parameters,including auxiliary switch contacts are not overloaded.

3.2.Around and above contactor to leave enough space for insulation,to ensure the safety of use.

3.3.When you power up the control but there is no response,the power should be immediately cut off andcheck the reasons of control power,to avoid burnt out solenoid.

3.4.When the contactor is used to control inductive loads,recommended the RC protection or varistor protection of overvoltage absorption protection device to protect the load security.

3.5.When the electromagnetic system have strong magnetic attraction when it’s in working,we should keep the things with ferromagnetic material away form the machine.

3.6.The contact device is not suitable carries on the series joining-up work.

3.7.Main circuit connection principle:the upper end(quiet side) into the line side,the lower end (moving end)is the outlet end.
