Circuit Breakers are essential components of every modern electrical system. These devices are used to protect both the system and the user from potential dangers caused by short circuits and overcurrents. The IELHK21-1REC4-33372-1-V is a type of Circuit Breaker commonly used in industrial, residential and commercial applications.

The IELHK21-1REC4-33372-1-V is a type of circuit breaker that combines both current and thermal protection into one device. This type of circuit breaker has a higher breaking capacity than other types, making it ideal for heavy-duty applications. It features high current ratings of up to 6,000A and a thermal capacity of up to 12,000A. The IELHK21-1REC4-33372-1-V also features a locking mechanism, which ensures that the circuit breaker remains closed and safe during operation.

The IELHK21-1REC4-33372-1-V operates using a three-contact system, wherein a pre-calibrated bimetallic element is held between two contacts. When current flows through the bimetallic element, it expands and creates an opening. This opening then triggers the circuit breaker and opens the circuit. The thermal protection is provided by the bimetallic element, which expands faster when the current is high. This, in turn, trips the breaker even if the current has not yet reached its current rating.

The IELHK21-1REC4-33372-1-V is suitable for applications that require high protection levels such as power transformers and motors. It is also designed for reliability, durability and efficiency, making it an ideal choice for industrial and commercial applications. Additionally, the IELHK21-1REC4-33372-1-V is UL listed and CSA approved, ensuring that it meets the highest safety and performance standards in the industry.

Overall, the IELHK21-1REC4-33372-1-V is a great example of the reliability and protection circuit breaker technology can provide. With its high current ratings and thermal protection, this type of circuit breaker can provide reliable protection for industrial, residential and commercial applications. It is UL listed and CSA approved, which means that it meets the highest safety and performance standards in the industry.
