Introduction to LELH21-37185-2-V

This article will explain the application field and working principle of the LELH21-37185-2-V circuit breaker. The LELH21-37185-2-V is a type of electrical circuit breaker, or protection device, specifically designed for use in medium-voltage electrical systems. Circuit breakers are designed to protect equipment and people from the harmful effects of an electrical fault or overload. They offer both a physical and an electrical barrier between the devices being protected and the high-voltage electricity.

Application Field of LELH21-37185-2-V

The application field of the LELH21-37185-2-V mostly consists of medium-voltage electrical systems. The LELH21-37185-2-V is designed to provide protection for medium-voltage electrical systems, such as those found in commercial and industrial buildings. The LELH21-37185-2-V is suitable for use in applications such as motor control centers, power control centers, and in switchgear. The LELH21-37185-2-V is capable of providing protection for both single-phase and three-phase circuits.

Working Principle of LELH21-37185-2-V

The working principle of the LELH21-37185-2-V is based on the use of two separate but complementary components--an overcurrent protection element and a thermal protection element. The overcurrent protection element operates by measuring the current passing through the circuit and detecting when it reaches a certain level. When this happens, the element will trigger the circuit breaker to trip, breaking the circuit and preventing any further current from passing through. The thermal protection element works by measuring the temperature of the circuit and detecting when it reaches a certain level. When this happens, the element will trigger the circuit breaker to trip, breaking the circuit and preventing any further current from passing through.

Conclusion

The LELH21-37185-2-V is a type of circuit breaker designed for use in medium-voltage electrical systems. The application field consists mainly of medium-voltage electrical systems, such as those found in commercial and industrial buildings. The working principle of the LELH21-37185-2-V is based on the use of two separate components--an overcurrent protection element and a thermal protection element. The LELH21-37185-2-V is capable of providing protection for both single-phase and three-phase circuits.
