Circuit Breakers: LMLK1-1REC4-37531-70-V Application Field and Working Principle

A circuit breaker is an electrical device that protects an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. But one type of circuit breaker, the LMLK1-1REC4-37531-70-V, can provide protective features not found in other breakers. This article will explain the application field and working principle of LMLK1-1REC4-37531-70-V circuit breaker.

Application Field

The LMLK1-1REC4-37531-70-V circuit breaker is a versatile protective device for residential, commercial and industrial applications. It is widely used as a device to protect circuits in homes, apartments, schools, hospitals and factories.

This type of circuit breaker is designed to be used in circuits with currents of up to 62A AC. It can be used in single-phase and three-phase power supply systems and is suitable for use in AC50, AC200 and AC220 circuits. It can also be used in low voltage DC applications.

The LMLK1-1REC4-37531-70-V circuit breaker has a temperature-compensated mechanism that allows it to be used in environments with extreme temperature variations. It is also designed to withstand electrical shock and impact, making it an ideal choice for hazardous and explosive environments.

The LMLK1-1REC4-37531-70-V circuit breaker is also available with optional features, such as shunt trips, ground fault detection and thermal protection. These features provide additional protection for the circuit and can help to reduce the risk of electrical fire.

Working Principle

The LMLK1-1REC4-37531-70-V circuit breaker is designed with a bimetallic strip as its core element. A bimetallic strip consists of two different metals welded together so that when the two metals expand or contract at different rates, they create a mechanical force. This force is used to trip the circuit breaker, breaking the circuit and protecting it from damage.

When the current passing through the circuit breaker exceeds the circuit breaker\'s rated current, the bimetallic strip begins to bend until it reaches a critical point and the circuit breaker trips. This protects the circuit by preventing excess current from damaging the electrical components. The circuit breaker can then be reset when the bimetallic strip cools down and returns to its position.

When the LMLK1-1REC4-37531-70-V circuit breaker is used in DC applications, its working principle is slightly different. Instead of a bimetallic strip, it uses a thermal device to detect overload or short circuit. This device works by detecting the rise in temperature caused by excessive current, and when the temperature reaches its critical point, the circuit breaker trips.

The LMLK1-1REC4-37531-70-V circuit breaker is designed to provide superior protection against electrical faults. Its robust design and reliable performance make it one of the most versatile and reliable circuit breakers available on the market.
