Circuit breakers are electromechanical devices designed to protect electrical systems, appliances, and other items from damage caused by too much current. These devices are used in both high-voltage and low-voltage applications to prevent dangerous overloads and short circuits. In commercial and industrial systems, circuit breakers provide greater safety and operational performance, as well as the flexibility of controlling larger or more complex switchgear systems.

IDLHK11-224-43 is a special type of circuit breaker that is ideal for use in high-voltage applications up to 15kVac. It is a manually operated circuit breaker, meaning it can be opened or closed manually by the operator. It features a movable contact and an interconnected trip unit, both of which are housed in a stainless steel enclosure. It has an operating current range of 80-25,000A and a rated short-circuit value of 50kA.

The working principle of the IDLHK11-224-43 is based on the theory of thermal overload protection. When the circuit breaker is closed, current flows through its components and the heat generated increases the temperature of the contacts. If the current exceeds the maximum permitted by the breaker, the temperature of the contacts rises significantly and the trip unit senses the increase and trips the breaker. Once the current has been reduced or disconnected, the breaker can be reset and the circuit can be re-energized.

The IDLHK11-224-43 is a versatile and reliable circuit breaker that is suitable for use in a wide range of applications. It can be used in industrial, commercial, and residential installations to provide protection against excessive current, short circuiting, and over-voltage. It is designed to meet the requirements of UL 489 standards, and it is certified both for indoor and outdoor use.

The IDLHK11-224-43 is an excellent choice for applications that require reliable and cost-effective protection. Its manually operated design makes it easy to install and maintain, and its compact size and lightweight construction make it ideal for small and medium-sized installations. It is highly durable and can withstand repeated operation without sacrificing performance.

In summary, the IDLHK11-224-43 is a high-voltage manually operated circuit breaker ideal for use in industrial and commercial applications. It offers reliable overload and short-circuit protection, is compliant with UL 489 standards, and is simple to install and maintain. Its compact, lightweight design make it suitable for small and medium-sized installations, and its durable construction ensures long-term performance.
