Circuit breakers are an integral part of modern life, providing the necessary protection for electrical systems, appliances and devices. The LMLK1-30126-1-V is a circuit breaker designed to protect against short circuits and over-currents in industrial applications. It is suitable for a variety of applications and is UL 1077 listed as a Type C device.

The LMLK1-30126-1-V circuit breaker is a re-settable, thermal-magnetic type that meets the UL 489 and UL 1077 industrial requirements. It uses a manual reset thermal-magnetic trip mechanism for overload protection, combined with a thermally-responsive actuator for short circuit protection. This combination of overload and short circuit protection provides reliable operation and protection for the electrical circuit.

The LMLK1-30126-1-V circuit breaker has an adjustable trip range and is available in a variety of frame amperages. It also features a factory set rated current, which is marked on the external label, and manual reset functionality. This manual reset functionality allows the user to reset the breaker after a fault has been identified and fixed, thus providing additional protection against system damage.

The LMLK1-30126-1-V circuit breaker works according to the thermal-magnetic principle. It employs a temperature sensitive bimetallic strip that controls the operation of the device. When the current passing through the breaker exceeds the rated value, a metal strip will heat up and bend to trip the breaker. This will interrupt the circuit and break the current path, thus preventing further damage to the electrical circuit.

The thermally-sensitive actuator is connected to the metal strip and is responsible for providing short-circuit protection. When the current passing through the breaker exceeds the rated value, the temperature of the metal strip will rise and the actuator will detect the temperature rise. When it does, the actuator will close the trip contacts and break the current path, thus providing protection against an unwanted short circuit.

The LMLK1-30126-1-V circuit breaker can be used in a range of industrial applications including motor controls, control systems, lighting systems, power supplies and IT/telecom equipment. It is suitable for use with both AC and DC currents up to 1000V and is UL 1077 listed as a Type C device. The LMLK1-30126-1-V circuit breaker is designed to provide reliable overload and short circuit protection, and reduce the risk of system damage due to electrical overloads or short circuits.
