Introduction

This article is about the IELHK11-34396-90-V circuit breaker and its application field and working principle. Circuit breakers are the most important electrical switching device used to prevent or limit electrical fires, shocks, and overloading. They are electromechanical devices that are designed to protect an electrical circuit from overloads and short circuits by automatically interrupting the current flow. In this article, we will discuss the application field, technical characteristics, and working principle of IELHK11-34396-90-V circuit breaker and give an overview of the different types of circuit breakers available.

Application Field

IELHK11-34396-90-V circuit breakers are designed for use in the low-voltage power distribution system up to a maximum of 690V AC or 1000V DC. They are suitable for residential, commercial, and industrial installations. They can be used as circuit protection devices for circuits carrying up to 35kA or 400V DC at 50/60 Hz. The maximum operating current is 690V AC and 1000V DC.

Technical Characteristics

The IELHK11-34396-90-V circuit breaker is designed with a molded case and a current rating of 35kA. The contact gap is 1.3mm and the rated ultimate short circuit capacity is 35kA. The voltage rating is up to 690V AC and 1000V DC. The rated frequency is 50/60 Hz and the maximum operating current is 690V AC and 1000V DC. It features a mechanical life of 8500 operations with an electrical life of 1000 operations. The mechanical operation time is less than 30ms and the dielectric strength is up to 690V. The circuit breaker is also equipped with a manual override switch that allows it to be switched off in case of an emergency.

Working Principle

The working principle of the IELHK11-34396-90-V circuit breaker is based on the operation of an electromagnetic field. The principle of operation is simple, when a current is applied to the breaker, an electromagnetic field is created and causes the contacts to open in case of an overload. The breakers can be manually operated by means of an external switch or automatically by sensors which detect the overcurrent condition. The operation is done quickly, usually within 30 milliseconds.The circuit breaker can operate at normal or maximum temperatures depending on the application. If the temperature goes too high, the breaker will trip and open the circuit to prevent further damage. The breaker also has overvoltage protection that will trip the breaker in case of a power surge.

Conclusion

The IELHK11-34396-90-V circuit breaker is designed for low voltage power distribution systems up to 690V AC. It has a rated ultimate short circuit capacity of 35kA and a mechanical and electrical life time of 8500 and 1000 operations respectively. The working principle of the circuit breaker is based on the operation of an electromagnetic field that opens the contact in case of an overload. The working principle is simple and can be triggered manually or automatically depending on the application. The breaker also has overvoltage protection that will trip the breaker in case of a power surge.
