Circuit breakers are a form of protection device used in many electrical systems to protect components from electrical overloads and other potentially damaging conditions. Circuit breakers work by cutting off the electrical power to the component being protected in the event of an overload or other problem. IEGH66-35127-3-V is a type of circuit breaker device.

The IEGH66-35127-3-V

The IEGH66-35127-3-V is a three-pole, direct-acting circuit breaker rated up to 10 kV AC/15 kV DC. It was designed specifically to be used in high-voltage applications, such as power grid systems, electric utilities, and industrial facilities. The breaker is equipped with current-limiting and short-circuit protection features that allow it to quickly interrupt the flow of current and safely shut down the system should an overload or short circuit occur.

Applications

The IEGH66-35127-3-V is used in a variety of applications ranging from residential power systems to industrial power grids. It is often used as the primary circuit protection for domestic, commercial, and industrial installations. Additionally, the breaker is used in generator sets, distribution systems, switch gear panels, and motor control centres. It is also used in renewable energy systems and other applications requiring extreme protection from high-voltage power surges.

Working Principle

The IEGH66-35127-3-V is equipped with a thermal-magnetic trip unit that includes a bimetallic thermal element and a solenoid-operated magnetic trip unit. During normal operation, the bimetallic element is able to detect changes in temperature, while the solenoid-operated magnetic trip unit is designed to detect any increase in current level. When the thermal or magnetic trip unit sense an overload or short circuit condition, the breaker will quickly open to cut off the power.

In addition to the thermal-magnetic trip unit, the IEGH66-35127-3-V is also equipped with a shunt trip, a manual trip, and a remote trip mechanism. The shunt trip allows the breaker to be opened remotely, while the manual trip allows the breaker to be opened manually from any location. The remote trip mechanism allows the breaker to be opened from a remote station, such as a control room.

Safety Features

The IEGH66-35127-3-V has several safety features that help ensure the protection of both people and equipment. These features include a detection and indication mechanism for overvoltage, undervoltage, and trip currents, as well as a voltage disconnector to prevent reenergizing of the circuits in the event of a short circuit.

The IEGH66-35127-3-V also has an adjustable instantaneous trip function that provides an adjustable current level at which the breaker will trip. This helps prevent the breaker from tripping due to minor inrush current surges. In addition, the breaker has a built-in anti-pumping feature that helps prevent multiple trips from occurring due to a single event.

Conclusion

The IEGH66-35127-3-V is a high-quality, three-pole, direct-acting circuit breaker designed to provide reliable protection in a variety of high voltage applications. It has a variety of safety features, including current-limiting, short-circuit protection, and adjustable instantaneous trip settings. Additionally, the breaker has additional protection in the form of a voltage disconnector and an anti-pumping feature. This makes it an excellent choice for any installation needing reliable and efficient circuit protection.
