Circuit Breakers: LMLHPB11-1REC5-34823-3-V Application Field and Working Principle

Circuit breakers are safety devices in electrical circuits that disconnect electrical power when it is necessary to protect people and equipment. Circuit breakers are a type of switch used to control or protect electrical circuits, including circuits operating at unusually high currents or voltages. A circuit breaker is essential for safety and proper operation of any electrical system. The LMLHPB11-1REC5-34823-3-V is a specific type of circuit breaker used in many industrial applications.

Application Field

The LMLHPB11-1REC5-34823-3-V circuit breaker is designed for use in large industrial applications such as factory automation, manufacturing, and power plants. It is suitable for use in DC systems up to 25 kV, up to 1500 Amperes, and 480VAC applications. The LMLHPB11-1REC5-34823-3-V is also designed to protect systems from over-currents caused by short circuits, arc faults, and ground faults. In addition, it is designed to protect high-voltage systems from overvoltages due to transient conditions such as lightning strikes, faults on the power grid, or other external events.

Working Principle

The LMLHPB11-1REC5-34823-3-V is a two-pole circuit breaker that works by breaking the current path when an overload condition occurs. It can detect both AC and DC faults and automatically disconnect itself from the power line. When an over-current passes through the circuit breaker, it triggers a trip mechanism which releases a spring-loaded latch that interrupts the current flow. The circuit breaker also has an adjustable trip current selector that allows it to be adjusted according to the system requirements.

The trip mechanism is based on the use of a thermal rating, where the thermal element heats up due to the current flow. When the thermal element reaches its predetermined temperature, it tripped and thus protects the surrounding system from an overload. Additionally, the LMLHPB11-1REC5-34823-3-V is equipped with an arc-fault detector that trips the breaker when an arc fault is detected in the system.

The LMLHPB11-1REC5-34823-3-V is a reliable circuit breaker that can effectively protect industrial systems from overloads and overvoltages. It is also designed for ease of installation and maintenance with features such as adjustable trip settings and diagnostic indicators that display the current breaker status.
