Circuit breakers are an important part of the electrical system, providing protection against short circuits and over currents. The LMLHPK11-1RS5-32813-125-V is a specialty circuit breaker, designed for applications where quick action and high current ratings are required. It has a fast-acting, self-contained current-limiting system that prevents damage to downstream equipment and reduces the risk of electrical fires.

Application Field of LMLHPK11-1RS5-32813-125-V

The LMLHPK11-1RS5-32813-125-V circuit breaker is designed for industrial, commercial, and residential applications in stringent environments. It is specifically designed for sites where long operations under a high ambient temperature are required, such as machine tools, telecom stations, transformers, and other power distribution applications. It works by using a thermal-magnetic trip unit with a time delay, which limits the amount of damage to the system in the event of an overload or a short circuit. This makes the circuit breaker suitable for applications where high currents, especially when installed in conjunction with electrical transformers and distributed power systems.

Working Principle of LMLHPK11-1RS5-32813-125-V

The working principle of the LMLHPK11-1RS5-32813-125-V circuit breaker is quite simple. The circuit breaker is composed of two parts: a thermal-magnetic trip unit and a time delay. When an overload or short circuit occurs, the thermal-magnetic trip unit senses the excessive current and trips the circuit breaker instantly. Then, the time delay stops any subsequent current flow and prevents downstream equipment from getting damaged.

The thermal-magnetic trip unit works by monitoring the current and temperature of the electrical system. When the current or temperature exceeds a pre-defined threshold, the unit trips the circuit breaker. The time delay adds a few additional milliseconds of delay and allows the circuits to cool down before the current is restarted.

The LMLHPK11-1RS5-32813-125-V is a reliable, safe, and economical solution for applications where quick action and high current ratings are required. Its fast-acting self-contained current-limiting system is designed to protect downstream equipment from damage and reduce the risk of electrical fires.
