Circuit Breakers are indispensable components used in all aspects of the electrical industry. Every electrical distribution system needs circuit breakers to protect the system from faults and overloads. IEGX2-29499-1 is a type of circuit breaker specifically designed to protect electrical equipment from short-circuit currents.

The IEGX2-29499-1 circuit breaker is capable of breaking both overload and short-circuit currents. It is designed to quickly detect these current abnormalities, reduce the fault current and trip the circuit breaker, thus preventing any further damage to the electrical equipment. The IEGX2-29499-1 is suitable for use as a branch circuit breaker in panel boards, switchboards, switchgear and other electrical power distribution systems.

The IEGX2-29499-1 is a fast-acting circuit breaker that employs a thermal-magnetic trip unit to detect overload and short-circuit currents. It is rated for 600 volts and has a continuous current carrying capacity of 80 amps. It is available in single, two, and three pole configurations and is UL listed, indicating that it has been tested and verified to meet safety standards.

The main operating principle of the IEGX2-29499-1 is the thermal-magnetic trip unit, which contains both a thermal heat element and a solenoid-operated magnetic trip mechanism. The thermal heat element is a positively temperature-sensitive bi-metallic strip that is mounted within the circuit breaker and senses overload current. When the overload current exceeds the rated value for a sustained period of time, the bi-metallic strip becomes heated, moves and actuates the tripping mechanism of the circuit breaker.

The other part of the trip unit is the magnetic trip mechanism, which responds to the presence of the high fault current. It consists of a solenoid-operated trip lever, which is connected to a spring-loaded mechanism. When the current value exceeds the rated value, the magnetic field generated by the solenoid causes the trip lever to move rapidly, activating the spring-loaded mechanism and tripping the breaker.

The IEGX2-29499-1 is also designed to meet various international standards, like IEC 60947, UL 489 and Canadian CSA C22.2. All these standards are related to circuit breaker testing, construction and inspection. To ensure its stable performance, the IEGX2-29499-1 circuit breaker features a built-in time delay, which helps to prevent nuisance tripping due to small overloads or motor starting currents.

In conclusion, the IEGX2-29499-1 is an efficient and reliable circuit breaker which offers a great combination of performance and durability. Thanks to its fast-acting and reliable trip unit, it is suitable for use in a variety of applications, from panel boards to switchgear. It can provide effective protection against both overloads and short-circuits, making it an ideal choice for all types of electrical power distribution systems.
