Circuit breakers are important safety components used in electrical systems to protect against excessive current and prevent circuit breakouts from occurring. The IELHK 11-1-51-3.00-01-V is a common circuit breaker used in industrial or commercial applications. In this article, we’ll take a deeper look into the application field and operating principle of this circuit breaker.

The IELHK 11-1-51-5.00-01-V is an air circuit breaker designed to protect circuits from short-circuiting, excessive current, or overload. It is most commonly used as a main circuit breaker in large industrial or commercial electrical systems. It is rated for 15-17kA at 480V with a maximum voltage of 690V AC. It has a maximum interrupting rating of 100kA and a standard size of 6-1/8” x 2-1/4”.

The IELHK 11-1-51-5.00-01-V operates on the principle of thermal-magnetic tripping. This means that it combines two separate tripping mechanisms: thermal and magnetic. The thermal portion of the circuit breaker uses a bi-metal strip that is free to move in response to changes in temperature. This strip is connected to the main contacts of the circuit breaker. As current increases, the temperature of the contacts increases, making the bi-metal strip expand, which then causes the circuit breaker to trip.

The magnetic portion of the circuit breaker uses an electromagnet connected to the main contacts. When current exceeds the rated value, the electromagnet produces a magnetic field that causes the trip lever to move. This movement causes the circuit breaker to trip.

The IELHK 11-1-51-5.00-01-V is capable of handling extremely high currents. This is why it is the preferred choice for industrial or commercial applications. It is also very easy to install as it requires minimal wiring and no specialized tools. In addition, it can be used for both single and three-phase systems.

In conclusion, the IELHK 11-1-51-5.00-01-V is a reliable and versatile circuit breaker. Its combination of thermal and magnetic tripping mechanisms make it ideal for industrial or commercial applications where power must be shared or distributed safely. Its high current rating, ease of installation, and its ability to be used in both single and three-phase systems make it an ideal choice for any application.
