Circuit Breakers

Circuit breakers are a type of electrical device that is designed to protect an electrical circuit from damage caused by an overload. Typically, they are used to prevent electrical circuits from exceeding their rated current-carrying capacity.

LMLB1-1REC4-51-30.0-1-01-V Application Field and Working Principle

The LMLB1-1REC4-51-30.0-1-01-V circuit breaker is designed to protect overcurrent in 600 Volts and under 400 Amperes three-phase systems. This particular breaker is suitable for residential, commercial and industrial applications.

The working principle of the LMLB1-1REC4-51-30.0-1-01-V breaker is based on the thermal-magnetic characteristics of the device. When the current passes through the breaker, the core of the breaker unravels and an arc is created, which causes the breaker to trip and disconnect the power from the circuit. The trip time is adjustable depending on the current passing through and the environmental factors, such as temperature.

When the overcurrent passes through the breaker and the temperature rises, the bimetallic strips in the breaker will bend, causing the breaker to trip. This action also causes the breaker’s handle to move, which triggers the internal interlock mechanism, and the contact is opened.

The LMLB1-1REC4-51-30.0-1-01-V Breaker is designed with a manual reset push button. This feature allows a user to manually reset the breaker, allowing the circuit to be reset without the need to turn off the power.

For optimal performance, the LMLB1-1REC4-51-30.0-1-01-V breaker should be inspected and tested regularly. It is important to ensure that the breaker is not damaged or worn before resetting, as this could cause further damage to the circuit.
