Circuit Breakers – IDLHK11-1-61-20.0-AB-91 Application Field and Working Principle

Circuit breakers are integral components of any electrical system. Circuit breakers are used in industrial, commercial, and residential applications to protect electrical components from damage due to overloading and short-circuiting. The IDLHK11-1-61-20.0-AB-91 is one type of circuit breaker whose application field and working principle are discussed in this article.

Application Field of IDLHK11-1-61-20.0-AB-91

The IDLHK11-1-61-20.0-AB-91 circuit breaker is designed for very low voltage applications, such as 120/240 VAC single-phase systems and 208/240 volts three-phase systems. It is commonly used in residential and commercial structures, including residential service panels, commercial landlord panels and HVAC systems. The breaker also can be used in permanent buildings, trailers and mobile homes. Furthermore, the IDLHK11-1-61-20.0-AB-91 circuit breaker is approved for use in UL 489 branch circuit disconnects.

Working Principle of IDLHK11-1-61-20.0-AB-91

The IDLHK11-1-61-20.0-AB-91 circuit breaker is an interrupting device designed to provide protection from overloads, short circuits, and ground faults. In normal operation, the breaker trips when an over current is detected. This over current is detected by the heater bimetal inside the breaker. The heater bimetal is a strip of metal with a high thermal mass, which is heated by the current flow. If the current exceeds the breaker\'s trip setting, the heater bimetal will deflect, pushing the trip block until it reaches the trip lever, and then trips the breaker off.

In addition to over current protection, the IDLHK11-1-61-20.0-AB-91 circuit breaker also provides ground fault protection. Ground fault protection is a safety measure that helps to protect against dangerous electrical shock. The breaker is equipped with a shunt trip device that senses a ground fault current and then trips the breaker off. Ground fault protection is designed to intervene before a person experiences electrical shock.

Conclusion

The IDLHK11-1-61-20.0-AB-91 is a type of circuit breaker that is designed for very low voltage applications. It is typically used in residential and commercial structures, trailers, mobile homes, and other permanent buildings. The breaker provides protection from overloads, short circuits, and ground faults. The breaker trips off when an over current is detected by the heater bimetal inside the breaker, and can also trip if it detects a ground fault current.
