Working Principle of L2 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 L2 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. Good Reliability: Our products can work normally under up to 50V AC and 250V DC. After power off, you can use the button to manually restore and reset. The compact design provides you with a high-density circuit protection configuration.
2. Excellent Material: Made of high quality copper material with excellent thermal conductivity and corrosion resistance. 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. You can use these in salt water environments that are very corrosive.
3. Easy to Install: The overload protector needs to be installed in a 3/8 inch round hole. The perfect substitute for aging circuit breakers. If you plan to use it to replace the aging circuit breakers, you can install it without modification. Please test before installation.
4. Safety Protection: Push-to-reset operation with black manual reset button, come with a waterproof button cap to protect from bad weather. Long service life, you don't need to replace the overload protector frequently. It can provide effective protection for the electrical system, squirrel cage motor, winding motor over current, short circuit, phase loss, phase imbalance, phase error and starting process.

Application

Widely Application: L2 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.
