Circuit Breakers are essential components that serve to protect electrical systems and components from damage due to overload or short circuit. One popular model of circuit breaker is the LMLK1-1RLS4-31464-30-V. This device is a thermal-magnetic trip unit specifically designed for low voltage power and lighting panel applications. This document explores the application field and working principle of this popular circuit breaker.

The LMLK1-1RLS4-31464-30-V circuit breaker is designed to detect overload or short circuit conditions in electrical power and lighting circuits. It is primarily used in industrial, commercial, and residential applications to protect both motors and lighting loads. The unit is equipped with a manual reset function, allowing for quick reset after a trip or overload situation has been cleared. Additionally, the unit includes a green indicator light which informs the users whether a trip has occurred. The device is built to comply with UL 489, UL 1077 and CSA C22.2 standards.

The working principle of the LMLK1-1RLS4-31464-30-V circuit breaker revolves around the thermal-magnetic trip unit. The thermal-magnetic trip unit combines an electro-mechanical thermostat and a bi-metal strip to monitor the current flowing through the circuit. When an overload or short circuit is detected, the unit will trip, signaling an alarm and breaking the circuit. The manual reset functions allows users to restore power after the overload or short circuit has been cleared. The device also features an adjustable current trip that can be used to adjust the trip level from 10 to 20 times the rated current.

In addition to its protection against overloads and short circuits, the LMLK1-1RLS4-31464-30-V circuit breaker also provides protection against line surges. The breaker includes a multi-pole air gap which reduces the voltage levels that can be passed when compared to a standard surge protector. This reduces the chances of a line surge causing damage to equipment and components. The device is also certified for reverse polarity protection, protecting against reverse flow of current.

The LMLK1-1RLS4-31464-30-V circuit breaker is a reliable and popular choice for protecting electrical systems and components. Its thermal-magnetic trip unit combines electro-mechanical thermostat and bi-metal strip technology to detect overloads and short circuits. The device also provides protection against surging voltages and reverse polarity issues. The adjustable current trip allows users to set the trip level to their desired level and the manual reset feature allows the device to be quickly reset after a trip or overload situation has been cleared. As a result, this popular device is suitable for use in industrial, commercial, and residential applications.
