Circuit breakers are essential components in any electrical system tailored either for residential, commercial or industrial applications. IEG66-28195-4-V is a type of circuit breaker made specifically for circuits rated up to 630 amperes in AC applications and 700 volts in DC applications.

The IEG66-28195-4-V will open the circuit and “break” the flow of electricity when a certain amount of current flows through it. This is done by having a current sensing coil monitored by one or more electromagnets that trigger a mechanism opening the contacts, thus “breaking” the circuit’s path. The device is designed to perform this action for three reasons:

• To protect overloaded circuits during abnormal conditions such as short circuits and ground faults.
• To control the launch and stop of electric motors.
• To protect the circuit from exceeding the nominal current.

To ensure its proper functioning, the IEG66-28195-4-V circuit breaker must be installed within an enclosure and be capable of acting when a current given as “trip current” is reached. The trip current is the amount of current that will cause the contacts of the circuit breaker to open, thus “breaking” the circuit. When a current of 6 times the nominal current is reached, the circuit breaker must open within at least 250 milliseconds to prevent major damage to the circuit.

The IEG66-28195-4-V is mainly used in residential and commercial applications that have a need for a medium sized circuit breaker due to its specifications having a rating of up to 630 amperes AC and 700 volts DC. It is designed to meet commercial standards set by the Underwriters Laboratories. This circuit breaker is encased in a white plastic exterior to guarantee its protection against any voltage fluctuations and overcurrents.

The IEG66-28195-4-V circuit breaker offers excellent performance and reliability. As it has several mechanisms for protection and monitoring, it provides a sense of security for any electrical system. It has low failure rates, ensuring the safety of any installation and its occupants. The circuit breaker requires minimal maintenance and it can be easily replaced in the event of any failure.

In conclusion, the IEG66-28195-4-V is an excellent circuit breaker option for residential and commercial applications. It ensures the safety of the installation by providing efficient and reliable protection against overcurrents, short circuits and ground faults. It is easy to install and minimal maintenance is required. The circuit breaker also meets all commercial standards set by the Underwriters Laboratories.
