Wholesale Thermal Overload Bimetal Motor Thermal Protection Switch 

 

Thermal protection is a method of detecting over-temperature conditions and disconnecting the power to the electronic circuits. Thermal protectors are specifically made for motors. When the motor's heat rises too high, the thermal protector turns off electricity. This stops the motor from overheating and catching on fire. Thermal protectors are placed internally inside the motor.

Thermal Protector Application

 

The thermal protector is suitable for various motors, electrical tools, chargers, transformers battery, fluorescent ballasts and lightings, electric pad, electric blanket, laminatorand Home appliances, etc.

 

Thermal protector technical requirements:

The lead wire  UL3135, 20AWG red silicone wire.   (customized)
Contact capacity:  50V 5A, contact type: normally closed. 
Contact resistance: When the contact is closed, the resistance between the lead wires is ≤50MΩ.  
Rated breaking temperature:  150±5°C; Rated reset temperature 105±15°C.  
Mechanical strength of lead wires or terminals:  should withstand static tension of 60N/ 1min without loosening, cracking, deformation and other defects    
The insulation resistance of the lead wire or terminal and the surface of the insulating layer of the casing ≥10MΩ.  
Electric strength:   

a. When the contact is normally closed, the lead wire and the insulating layer of the casing should withstand 1500V/1min without flashover and breakdown.

b. When the contacts are thermally disconnected, the lead wires should withstand 500V/1min without flashover and breakdown.
