Working Principle of L3 Circuit Breaker :
 

An overload protector (circuit breaker) protects the compressor by sensing temperature and current. It is composed of a set of normally closed contacts and bimetallic elements. The overcurrent overload protector is mounted on the outside of the compressor, in direct contact with the compressor casing and in series with the compressor windings. If the compressor cannot be started for some reason, the overloaded locked-rotor current will cause the bimetal element to heat up and bend rapidly, causing the contact to quickly trip, cutting off the current flowing through the compressor, thereby protecting the compressor. Similarly, if the motor of the compressor is abnormally heated and the temperature of the windings of the compressor is too high, the protector will heat up and trip, thereby protecting the compressor. As long as the cause of the failure is not ruled out, the compressor will start and stop with the action of the bimetallic element over and over again in the case of overcurrent and overload.

 

Kindly Note:

 

1. The breaker has a reset button that pops up when it trips, and the button cannot be pulled out manually to break the circuit.

2. The thermal breaker does not trip immediately, there is a delay based on the amount of overload.

The Product Size of L3 Series Manual Auto Reset Overload Protector Electric Welding Machines Thermal Magnetic Switch Breaker

The Feature of 3A 4A 5A 6A 7A 8A 10A 12A 15A 16A 20A 25A Manual Automatic Switchable Reset Thermal Magnetic Trip L2 Series 38 Series 88 Series Circuit Breaker Overload Protector Switch for AC socket:

1. perfect design: Compact, single pole, push-to-reset thermal circuit breakers. The circuit breakers are marked with clear specification onside including rated current, volts DCand volts AC. Push-to-reset operation with black manual reset button to make easy manual reset. 
2. Material: The shell is made of bakelite, which has excellent heat resistance, high mechanical strength, toughness and wear resistance, dimensional stability, corrosion resistance and excellent electrical insulation performance.
3. Protect the Line&Can be used again: When the load exceeds the rated current, this switch reset button will automatically cut off the circuit, the recoverable fuse will be automatically disconnected to a protective circuit. It can control the large current circuit, and thus play a role in protecting the line.

Application

Widely Application: L3 series thermal circuit breaker reset overload overcurrent protectors are widely used in the protection and monitoring of industrial electrical appliances in the machinery, metallurgy, building materials, chemical, textile industries, generators, ships, computers, air compressors, AC socket, etc.
