A circuit breaker is an electrical device which is designed to protect an electrical circuit from damage caused by overload or short circuit. The LMLK1-30125-1-V is a type of circuit breaker that is designed for medium-voltage applications. It is manufactured by Legrand, a leading manufacturer of electrical components and is UL-rated for safety.

The LMLK1-30125-1-V has a rated voltage of 8.5kV and a rated current of 1000A. It is suitable for use in industrial applications, such as motor starters, air conditioning units, and other large electrical appliances. It is also certified to meet all applicable requirements of National Electric Code.

The LMLK1-30125-1-V circuit breaker has a high breaking capacity, which enables it to effectively protect the circuit from overload and short circuit currents. It features a robust design, with a solid-state trip mechanism and a fail-safe design. It is made out of a durable high-temperature alloy, which makes it suitable for use in harsh environments.

The LMLK1-30125-1-V also has a special feature - a thermal trip device, which can be used to detect and prevent over-temperature conditions. It is designed to detect temperatures above the rated level of the circuit breaker, and will initiate a trip response if needed, which will disconnect the load from the circuit. This thermal trip device can also be used to protect the circuit from other types of faults, such as short circuits.

The working principle of the LMLK1-30125-1-V circuit breaker is based on a metal element located in the circuit itself. This element is called a bimetallic strip. When a current passes through the strip, it heats up and the bimetallic strip bends or buckles. This causes a switch or breaker to open, which then stops the current and disconnects the circuit.

The LMLK1-30125-1-V circuit breaker provides outstanding protection for electrical circuits in medium-voltage applications. It is built to meet all UL standards, and is also certified to meet National Electric Code requirements. It is a reliable, cost-effective solution for medium-voltage applications, and provides an effective way to protect these circuits from damage caused by overload or short circuits.
