Circuit Breakers

LELH11-36981-20-V Application Field and Working Principle

Circuit breakers are an important protective device for power systems. They perform an extremely important role in daily life and industry which is, to protect electrical circuits, equipment and occupants from the dangers of high electric currents caused by short circuits, overload or other faults. LELH11-36981-20-V circuit breaker is a high-breaking capacity circuit breaker with rated voltage of 220/380V, rated current of 20A and rated frequency of 50/60HZ.It is used widely in electrical and electronic control systems for the protection of circuit, wires, electric motors, equipment and appliances. This circuit breaker features high breaking capacity, good insulation, dust-proof and moisture-proof performance, and is also flame retardant, age resistant and corrosion free. Its operating temperature range is -25℃ to +85℃, and its voltage-resistance range is within 1000V. Its structure includes a housing, a contact, a spring, a lever and a trip handle, etc.The working principle of this breaker is based on both thermal and electromagnetic protection. When the temperature rises in the circuit because of the continuous supply of current, the breaker trips to reduce the current and prevent possible damage or harm from heat buildup. When the the current is too large, a magnetic field is generated that aids in the actuation of the trip lever. Both of these mechanisms are sensitive enough to detect and respond to dangerously high electric currents. The contact of LELH11-36981-20-V is made from silver, making it corrosion and wear resistant, while also providing good electrical conductivity. The contact is spring loaded and is designed to snap open in the event of an overload or short circuit, thus breaking the circuit connection and ensuring the safety of users and equipment. This breaker also includes a trip handle, which can be manually positioned to disconnect and isolate the circuit. This is done to prevent the circuit from being energized and also to ensure the safety of personnel when operating and maintaining the breaker. In the event of a power cut off, the above mentioned mechanism can be used to manually close the breaker so that the power supply can be resumed.In conclusion, the LELH11-36981-20-V circuit breaker, not only provides protection against electrical shocks and failures, but also ensures operator safety through its manually operated disconnection feature. It is an indispensable part of daily life and industry where the safety of the equipment and personnel is important.
