Circuit breakers play a vital role for many applications across homes, businesses, and industries. In modern electricity systems, circuit breakers are used for both switching and for protection from electrical faults. The IEGZX661-30634-2-V is a circuit breaker designed for use in high voltage, direct current applications. This circuit breaker combines the reliable performance of advanced vacuum interrupter circuits with a design that allows for easy placement and maintenance.

The IEGZX661-30634-2-V is designed to function in a broad range of applications including power transmission, switchgear, protective relaying, transmission lines, main circuit breakers, metering, and load centers. It is rated for service in a maximum ambient temperature range of 50 to 120 degrees Celsius, and can operate in voltage levels ranging from 8.5kV to 36kV. The IEGZX661-30634-2-V is equipped with a hydraulic-magnetic trip unit and is capable of opening on fault current in as little as 42 milliseconds.

The IEGZX661-30634-2-V circuit breaker is designed to provide protection for high voltage systems from fault currents such as electrical spikes or overloads. It features an arc-interruption process which relies on advanced vacuum interrupter technology. The breaker is capable of carrying large currents for its size, meaning it minimizes the arcing time between breaker plates. This also allows for a more complete clearing of the arcing zone, significantly reducing the risk of short-circuits.

In normal operation, the IEGZX661-30634-2-V operates with a system of electromagnets. The electromagnets are positioned near the switch contacts and connected to a coil source such as a transformer. When the switch contacts close, the electromagnets activate and draw a current through the switch contacts. This current creates an electro-magnetic force which keeps the switch contacts under tension. Following a fault, the electromagnets shut off and the current is allowed to flow through the circuit breaker, breaking the contact between the switch poles.

The IEGZX661-30634-2-V features a hydraulic-magnetic trip unit which monitors the current flowing through the switch contacts. When the current exceeds the predetermined threshold set by the user, the trip unit trips the breaker and opens the contacts. This allows the system to be protected from further damage and eliminates the risk of a dangerous electrical fire.

In addition to providing protection from fault currents, the IEGZX661-30634-2-V features several other features designed to improve performance and safety. The included thermal protection device ensures that the breaker does not overheat in hot environments, while the front mounted control lever allows for easy manual operation of the breaker. Additionally, the IEGZX661-30634-2-V comes with a remote control module which allows for easy integration into power systems.

The IEGZX661-30634-2-V is a reliable, high-performance circuit breaker designed for use in high voltage, direct current applications. Its advanced design allows it to provide protection from fault currents while also ensuring improved safety and usability. With its ability to carry large currents for its size and its efficient arc-interruption, the IEGZX661-30634-2-V is an ideal choice for many high voltage applications.
