Circuit breakers are electrical devices designed to quickly and automatically extinguish large current flows during abnormal operating conditions or surges. They protect a circuit’s wiring and components from overheating and damage, thus preventing an electrical short or fire. The LELZXK12-1REC5-35239-40-G2-V circuit breaker is an example of a device specifically designed for industrial and commercial applications.

Overview

The LELZXK12-1REC5-35239-40-G2-V circuit breaker is a high performance, low voltage breaker designed to handle the electrical load of industrial and commercial facilities. It is comprised of two parts: a breaker unit and a trip unit. The breaker unit is responsible for opening and closing the circuit, while the trip unit is responsible for sensing the current and tripping the breaker if an overload or short occurs.

Application Field

The LELZXK12-1REC5-35239-40-G2-V circuit breaker is designed to provide an extra margin of protection for electrical circuits with larger motors, pumps, and other industrial equipment that demand higher power requirements. It is suitable for harsh industrial conditions with ambient temperatures of up to 50 degrees Celsius and high vibration levels. It can also be used in high current applications like electric power plants, boilers, furnaces, and water treatment plants.

Working Principle

When an overload or short circuit occurs in the protected circuit, the LELZXK12-1REC5-35239-40-G2-V circuit breaker will trip, instantly disconnecting the circuit. This is done through a process known as arc fault interrupter. When the over-current is sensed, the trip unit sends a signal to the breaker unit, which interrupts the arc between the contacts and opens the circuit, disconnecting the electrical load.

The LELZXK12-1REC5-35239-40-G2-V circuit breaker is designed with built-in protections to help prevent accidental disconnection of the line. These protections include over-current protection, short-circuit protection, thermal protection, and ground fault protection. The breaker is also designed to have an adjustable current rating for better control over the area of protection.

The LELZXK12-1REC5-35239-40-G2-V circuit breaker is reliable and easy to install, making it a popular choice in the industrial and commercial sectors. It helps to protect personnel, equipment, and machinery from electrical hazards, thus ensuring the safety and reliability of the electrical circuit.
