LELPK111-1REC4-52-200.-A-01-V

Circuit breakers are essential components of any electrical system. It provides a measure of protection from overloading and short circuits in the electrical system. The circuit breaker that is under discussion in this article is the LELPK111-1REC4-52-200-A-01-V, a 30 μm membrane type low voltage AC high current circuit breaker. This breaker is used in various industrial and military applications for primary and secondary overvoltage protection, current limiting, reactive power flow control, and other related services.

The LELPK111-1REC4-52-200-A-01-V circuit breaker is an AC high current circuit breaker with an operating voltage of 19 V AC and a breaking capacity up to 16 kA. It has a 30 μm membrane type arc chute that is designed to limit the current when it is triggered thus preventing the circuit from overloading or short-circuiting. Its contact elements are made of silver, which makes it suitable for applications with higher voltage and short-circuiting conditions.

The LELPK111-1REC4-52-200-A-01-V circuit breaker is used in a wide range of applications such as power distribution grids, industrial control systems, power systems, aviation and military applications, short-circuiting protection for motors, and other related services. Its 30 μm membrane type arc chute enables it to be used as a current limitation device, providing additional protection for the circuits it is protecting.

In addition to its ability to provide overvoltage and current limitation protection, the LELPK111-1REC4-52-200-A-01-V circuit breaker has an adjustable trip point. This allows the user to set the trip point to a higher or lower level, depending on the application. This adjustable trip point also helps in controlling the reactive power flow in the circuit, providing additional protection to the load circuit.

The working principle of the LELPK111-1REC4-52-200-A-01-V circuit breaker is relatively simple. When the current surpasses the current level of the set trip point, the breaker trips and opens the circuit, allowing the fault current to be diverted or limited to prevent it from overloading the circuit. It also enables the circuit to be switched off or limited without having to manually switch it off, which is often required in the case of short-circuit protection.

In conclusion, the LELPK111-1REC4-52-200-A-01-V circuit breaker is an essential component in any electrical system. It is mainly used as an overvoltage and short-circuiting protection device in a wide range of applications. Its adjustable trip point helps in controlling the reactive power flow in the circuit, providing additional protection to the load circuit. It is designed to limit the current thus preventing the circuit from overloading or short-circuiting.
