Circuit Breakers are ​​electrical devices used to isolate power supply equipment from the electric grid in order to protect the system from damage caused by a fault or overcurrent. The LELH11-1-62-40.0-01-V Circuit Breaker is designed to provide protection for medium-voltage power distribution networks of up to 40KV or higher.

This breaker provides a single-pole, dual-function design for maximum protection and reliability. It is designed to be used in various power systems, such as distribution networks, power generation systems, and other industrial applications. The main purpose of the breaker is to protect the system from fault currents and overcurrent.

The working principle of the LELH11-1-62-40.0-01-V Circuit Breaker is based on the fact that when a fault or overcurrent occurs in the power system, a fault current will be generated. The breaker then trips to open or de-energize the circuit in order to protect against damage to the electrical system.

The breaker is composed of various components including an arcing chamber, a mercury-filled container, a contact system, and an external coil. The contact system is made of two independent poles, one of which is normally closed and the other is normally open. A control signal is sent to the breaker when there is an overcurrent or a fault, causing it to trip and de-energize the circuit.

The arcing chamber is filled with a gas mixture, which is used to quickly extinguish any arcs which may form during a fault. The gas mixture also cools the contacts of the breaker, ensuring that they remain in proper operating condition. The mercury-filled container operates as a safety feature, ensuring that the breaker will not close until it has been reset after the fault has been cleared.

The external coil is used to provide a trip signal to the breaker. This signal is then used to open or de-energize the circuit when a fault or overcurrent occurs. The coil also acts as a seal, preventing dirt and dust from entering the breaker.

The LELH11-1-62-40.0-01-V Circuit Breaker is designed for use in power systems of up to 40KV or higher. It is a reliable and efficient breaker that provides maximum protection to the system, thereby ensuring a safe and reliable operation of the power system.
