Circuit Breakers

A circuit breaker is vital and necessary equipment in overhead electricity distribution and protection system. Circuit breakers isolate the faulty part of electrical network from other parts, providing protection in case of an overload or short circuit.This is important in keeping damage to the network, and potential risks of electrocution and fire, to a minimum.

The IEGHF66-30867-10-V is a widely used dry-charged circuit breaker with a rated voltage of 3KV. It is mainly used in urban and rural power grids, substations, industrial and mining enterprises, and other occasions needing protection and control. It is ideal for low voltage power distribution and motor control, providing reliable performance and protection for power systems.

The IEGHF66-30867-10-V circuit breaker is composed of contact assemblies, operating mechanism, arc extinguishing system, casing, and other parts. The main function of the contact assembly is to establish and break electrical circuits depending on the operation of the control circuit. When a normal operation occurs, the contact assembly will automatically close and complete the circuit and provide conductive power supply. Once the short circuit occurs, the contact assembly will be forced open due to the fault current within the circuit, breaking off the connection and thereby interrupting current flow.

The integral electric leakage protection and overload protection will be triggered when the breaker is tripped due to short circuit or overload, providing protection to the transmission line, and to the breakers in the circuit. The overload protection will trip the breaker to its off position when the current in the circuit rises to an unsafe level. The electric leakage protection will sense any electric leakage current to ground or between adjacent lines and uses the same mechanism to trip the breaker to its off position. It is obvious how important this equipment is for the safety of a circuit and people in the area.

The IEGHF66-30867-10-V dry-charged circuit breaker has a compact and lightweight design that allows for easy installation and maintenance. Its advanced motorized mechanism design can provide stronger operating performance and improved switching capability, making it a reliable and cost-effective choice. The structure is well-built and highly reliable, and can be used in harsh environments.
