General Instruction

FR1 series auxiliary switch is a new type of auxiliary switch. It is made in the basis of FR functions to connect wire on the same-side of switch to solve the problems during customers` installation, like limited space or installation position. The FR1 series auxiliary switches broads the application range as a supplementary product of FR series auxiliary switches. Besides, it collects all the advantages of FR series auxiliary switches, and more applicable for controlling switch on & off functions, interlocking and signal circuits of high-voltage switch driving mechanism and conversions or group switches.

 

Service Condition
1.Ambient temperature:-40℃~+70℃.
2.Altitude:the installation spot is supposed not to exceed 5000m.
3.Humidity:the average value of relative humidity is max 95%, the average value of vapor pressure is max 2.2kPa in condition within 24 hours.the monthly average value of relative humidity is max 90%, the monthly average value of vapor pressure is max 1.8kPa.
4.Vibration acceleration is max 15m/s2.
5.There should be no evident air pollutions from dust, smoke, corrosives and combustible gas, vapor or salty fog.


Meaning of the Symbol  

 

E.g.: model no. FR1-28Y01 means FR1 series, 28 poles, screw connection mode,

Structure Features
FR1 series auxiliary switch is made up of multi-units with same structures. The contact point adopts silver alloy; the moving and stable contact are made of pure brass, and the insulation plate is made of superior imported inflaming retarding material with high strength, good insulation property and heat-resistance. Moreover, the reasonable structure of the switch ensures excellent dust-proof effects.


Working Principles
The FR1 auxiliary switch adopts indirect driving structure, it is working by square shaft to drive the cam wheel rotated, which in turn to push rod of switch to cause the moving of the contacts, thus to realize the control of the switch on & off function of the electric circuits.

 

Installation and Operation
1.Please refer to switch draft for mounting dimension.
2.The auxiliary switch should be installed to the target objects by fixing the extended screw shaft at both sides of the end plates. The switch itself should not be subject to external force, otherwise, it will become deformed and not able to work normally;
3.The serial numbers of contacts could be customized, and the switch operation should be within effective angles.
4.The rotating handle should not be subject to axial force, otherwise it will cause switch breakdown thus affect its normal operation.
5.Lead wire for FA auxiliary switch should be adopted plug in connecting method. 


Ordering Information
1.Pls indicate product name, specification & model No., quantity; 
2.Pls make sure the dimension of switch, work route and breaking
of contacts etc.
3.Other requirements.
