Circuit Breakers are electrical devices designed to control and protect electrical circuits from over-current and excessive temperature from making contact with other conductors. The IEGH66-29807-1-V is a type of Circuit Breaker used for protection in various applications.

The IEGH66-29807-1-V Circuit Breaker is a two-pole circuit breaker with thermal-magnetic tripping, trip-free mechanism and positive position release. It is UL Rated for a voltage rating of 480VAC at 50/60Hz, and has a maximum interrupting current rating of 10,000A. It has a current rating of 20A and is designed to protect electrical circuits from excessive currents.

The IEGH66-29807-1-V is designed for use in industrial, commercial, and residential applications including panel boards, switchboards, motor control centers and HVAC systems. It is suitable for protecting circuits from overload, short circuit, and ground fault protection. It is designed to meet all applicable UL and CSA standards, and is designed to be compliant with NFPA-70, National Electric Code requirements.

The working principle of the IEGH66-29807-1-V is based on two main components - the thermal-magnetic tripping mechanism, and the trip-free mechanism. The thermal-magnetic tripping mechanism is responsible for tripping the breaker when an over-current is detected. This mechanism senses the rate of change in the current flowing through the circuit and compares it to a pre-defined trip point. If the current exceeds the trip point, the mechanism will open the breaker.

The trip-free mechanism is responsible for preventing the breaker from re-closing once the breaker has tripped. This mechanism works by locking the current contacts and preventing them from being closed until the circuit has been reset. This ensures safety and prevents accidental re-closures of the circuit, which could result in further damage.

The IEGH66-29807-1-V circuit breaker is also designed with a positive position release which prevents the circuit being switched on until the breaker is back in the ‘on’ position. This prevents accidental voltage being applied to the circuit until the breaker has been reset.

In summary, the IEGH66-29807-1-V Circuit Breaker is a two-pole thermal-magnetic tripping breaker designed to protect electrical circuits from overload, short circuit and ground fault protection. It is designed to meet all applicable UL and CSA standards, and is designed to be compliant with NFPA 70, National Electric Code requirements. It is suitable for use in industrial, commercial, and residential applications, and is designed with a positive position release that prevents the circuit from being switched on until the breaker is reset.
