Circuit Breakers

A circuit breaker is an electrical device used to control and protect an electric circuit from damage caused by overload or short circuit. Circuit breakers are designed to trip the circuit and disconnect power to the load when an overload or short circuit is detected.

LMLK1-30124-1-V Application Field and Working Principle

The LMLK1-30124-1-V Circuit Breaker is a high-performance unit that is suitable for use in general duty applications. It is designed to protect residential, commercial and industrial electrical systems from overloaded or short-circuited circuits. The breaker is available in two poles and is rated up to 15 A and 277V maximum.

The LMLK1-30124-1-V Circuit Breaker is designed to detect and trip the circuit when it becomes overloaded or short circuited. The breaker is designed with a dual-stage operation, meaning that it detects the fault and then trips the circuit. When an overload or short-circuit is detected, the breaker will trip the circuit in one of two ways - Thermal Energy Release (TER) or Instantaneous Overcurrent Release (IOR).

Thermal Energy Release (TER) is the most common form of breaker operation and is designed to trip the circuit approximately 131% of the rated current. This method of trip action is suitable for residential, commercial, and industrial applications as it is designed to protect the circuit from over-current conditions.

Instantaneous Overcurrent Release (IOR) is another form of breaker operation and is designed to trip the circuit faster than the thermal energy release. This type of trip action is designed to provide protection from extremely large transient overcurrent conditions and is suitable for use in high-power installations.

The LMLK1-30124-1-V Circuit Breaker is designed with a variety of features to ensure reliable operation. It features an adjustable manual reset, test button, and over-temperature protection. Additionally, it is equipped with a visual indicator that notifies the user when the breaker has tripped. The unit is also protected by a weather-resistant housing, which is designed to withstand extreme temperatures and harsh environments.

The LMLK1-30124-1-V Circuit Breaker is an ideal choice for residential, commercial, and industrial applications. Its high-performance capabilities and adjustable features make it a reliable and robust unit that is designed to protect electrical systems from overload and short-circuit conditions.
