Circuit Breakers

Circuit breakers are safety devices designed to protect a circuit from excessive current and to provide an emergency shut-off in case of overloads. They are commonly used in applications such as residential homes, industrial plants, and commercial buildings. In modern times, circuit breakers are becoming increasingly important in protecting electrical systems from potential damage due to power surges and other conditions that can cause system failure. In this article, we will discuss the IDLHK11-1-52-70.0-K-91 circuit breaker and its application field and working principle.

What is a Circuit Breaker?

A circuit breaker is an electrical switching device used to protect an electrical circuit from damage caused by overcurrents or short circuits. It consists of a current-sensitive component such as an electromagnet, bimetal strip, or gas-filled tube that will trip when the current in the circuit exceeds a certain threshold. When the breaker trips, it opens the circuit and interrupts the flow of electricity, preventing damage to the circuit. Circuit breakers come in a variety of sizes and configurations to meet the needs of different applications.

What is the IDLHK11-1-52-70.0-K-91 Circuit Breaker?

The IDLHK11-1-52-70.0-K-91 circuit breaker is a type of miniature circuit breaker (MCB) designed for light and general-purpose circuits. It is a one-pole, B-Type breaker with a rated current of 70.0-K-91 and a response time of 1-2 milliseconds. The circuit breaker is designed to provide protection against short-circuiting, over-current, and over-voltage. It can be used in a wide range of applications, including residential, commercial, and industrial.

Application Field and Working Principle

The IDLHK11-1-52-70.0-K-91 circuit breaker is well suited for light and general-purpose applications such as small control panels or equipment with low starting capacities. It can be used to protect motors, lights, transformers, domestic appliances, and other electrical equipment from damage due to over-current or short-circuiting. This circuit breaker has a thermal-magnetic tripping mechanism, which combines the characteristics of thermal tripping and magnetic tripping. Thermal tripping is triggered when the current exceeds the rated current for an extended period of time, while magnetic tripping is triggered when the current exceeds the rated current within a predetermined time frame. After the circuit breaker trips, it can be reset and the circuit will continue to operate as normal.

Conclusion

The IDLHK11-1-52-70.0-K-91 circuit breaker is a reliable and versatile breaker that is suitable for a variety of light and general-purpose applications. It provides protection against over-current, short-circuiting, and over-voltage, and its thermal-magnetic tripping mechanism ensures quick response times. With its wide range of features and flexibility, the IDLHK11-1-52-70.0-K-91 circuit breaker is an ideal choice for residential, commercial, and industrial applications.
