Circuit breakers are designed to protect electrical circuits from overloads related to short circuits and surge currents. They are devices that protect equipment and people from catastrophic electrical events. LEL111-33489-20-V is a type of circuit breaker designed to provide protection in a wide range of applications.

LEL111-33489-20-V has a number of features that make it suitable for a variety of applications. It is rated for both single-phase and three-phase supplies and has a wide voltage range from 24-690 Volts. It has a rating of up to 20 Amps and is designed to protect against short circuits, ground faults and arcing. It can also be used as a load interruption device and can be used with a number of accessories to provide additional protection.

The working principle of LEL111-33489-20-V is relatively simple. When current exceeds the maximum level, the circuit breaker trips, cutting off the power supply and allowing the circuit to reset. The circuit breaker consists of a bimetal element which is sensitive to temperature changes caused by current flowing through the circuit. The bimetal element bends in response to the increase in temperature, which causes a mechanical switching event that breaks the circuit.

When the switching event occurs, the circuit breaker also trips a relay, which signals the circuit breaker to turn off the power supply before the circuit can be damaged or become overloaded. When the current returns to normal levels, the bimetal element returns to its original position and the circuit breaker is reset to its on position, allowing the circuit to be restored.

LEL111-33489-20-V is a versatile circuit breaker that is suitable for use in a variety of applications. It can be used in industrial motors, starting equipment, lighting circuits, and other high voltage applications. It can also be used to provide protection for motors, appliances, equipment, and structures.

LEL111-33489-20-V is a reliable and cost-effective circuit breaker that is designed to provide maximum protection against short circuits, ground faults, and arcing. It is versatile and can be used in a variety of applications, making it an ideal choice for a variety of applications.
