Circuit breakers are critical components in any electrical system, so understanding IEGZX21-1REC4-27160-1 circuit breakers is key to ensuring the safety and reliability of any equipment relying on an electrical power source. This article will provide an overview of the characteristics of this particular circuit breaker, its application field, and its working principle.

The IEGZX21-1REC4-27160-1 circuit breaker is a three-pole thermal-magnetic type circuit breaker. It is used for direct current (DC) operation and its current ratings are up to 1600 Amps. This circuit breaker type is widely used in medium-voltage (MV) power distribution systems because of its reliable electrical performance, low cost, and ease of installation and maintenance.

This particular circuit breaker is most commonly used in MV power distribution systems that are either radial or parallel. It can also be used in combination with a power transformer, making it suitable for many environments and applications.

The characterstics of this circuit breaker include a built-in thermal overload protection, an integrated low-leakage current interrupt capability, and a high short-circuit withstand capability. It also features a wide range of temperature ratings, with options for operating temperatures up to 105 degrees Celsius.

The application field of the IEGZX21-1REC4-27160-1 circuit breaker is mainly related to medium voltage power distribution systems. It can be used for both single-phase and three-phase applications, making it suitable for industrial, commercial, and residential power distribution systems.

The working principle of this circuit breaker is based on the thermal-magnetic design. This entails using a combination of thermal and magnetic forces to achieve reliable electrical power protection. When the current flowing through the circuit exceeds the thermal overload current rating, the thermal part of the breaker trips, thereby interrupting the current flow and protecting the system from overload.

In addition, the magnetic part of the circuit breaker becomes active when the current reaches the preset trip level. This component utilizes electromagnetism to open or close the contacts within the circuit breaker, thereby controlling the current level.

Overall, the IEGZX21-1REC4-27160-1 circuit breaker is an essential component in any medium voltage power distribution system, providing reliable and effective electrical overload protection for any equipment relying on an electrical power source. Its application field is largely related to medium voltage power distribution systems, while its working principle is based on a thermal-magnetic combination. Furthermore, the circuit breaker has a built-in thermal overload protection, an integrated low-leakage current interrupt capability, and a high short-circuit withstand capability.
