Introduction

Circuit breakers are electric devices that open or close a circuit when it detects an excessive current flowing through it. Circuit breakers are used to protect against overvoltage or overcurrent in an electrical system. The LELK111-31842-1 is a type of circuit breaker designed to provide circuit protection for electric motors and other loads. In this article, we will explain the application field and working principle of the LELK111-31842-1.

Application Field of LELK111-31842-1

The LELK111-31842-1 is a specific type of circuit breaker designed for motor protection. It is used for protecting motors against overload and short circuit. The LELK111-31842-1 has a current rating of 63A and is suitable for circuits with a voltage rating of up to 660V. It is designed to be used in motor control circuits, including reversing motor control circuits.

Working Principle of LELK111-31842-1

The LELK111-31842-1 works on the principle of thermal overload. It works by sensing when there is an overload or short circuit in the motor control circuit and opening the circuit to protect the motor and other components in the circuit. When an overload is detected, the LELK111-31842-1 trips and opens the circuit automatically. This causes the motor to stop and allows the user to check the circuit for the cause of the overload. A protective shield on the trip unit ensures that the user cannot inadvertently reset the circuit breaker when an overload has been detected, thus increasing the safety of the circuit.When the overload has been rectified, the circuit breaker can be reset and the motor restarted.

Conclusion

The LELK111-31842-1 is a circuit breaker designed for motor protection. It can be used for protecting circuits with a voltage rating of up to 660V and a current rating of 63A. It works on the principle of thermal overload and automatically trips and opens the circuit when an overload or short circuit is detected. The LELK111-31842-1 can then be reset and the motor restarted.
