Circuit breakers are essential and widely deployed pieces of electrical equipment used to protect electrical systems and electrical components. In the electrical industry, the IALHK11-1REC5R-39400-30 circuit breaker is a popular and reliable unit used for protecting the integrity of electrical systems and components. This article will discuss the application field and working principle of this circuit breaker.

Application Field

IALHK11-1REC5R-39400-30 circuit breakers find use in a wide range of industrial applications, including marine, mining, rail, and off-road vehicles. It is also suitable for domestic and commercial installations. For marine applications, it is designed to protect vessels from short circuits in electrical power systems, and additionally it can provide circuit isolations in hazardous areas, where other forms of electrical protection are not allowed. In mining applications, the breaker is used to protect people and equipment in hazardous areas from short circuits and equipment overloading.

In rail applications, the breaker can be used to protect the locomotive and railcar wiring from overloading, short circuits, and other electrical faults. The breaker can also provide circuit isolation within the electrical power system. In off-road vehicle applications, the breaker provides circuit protection from overloading and short circuits. It also provides circuit isolation to prevent accidents caused by arcing and sparking.

Working Principle

The IALHK11-1REC5R-39400-30 circuit breaker works on the principle of heat dissipation and current interruption. It has three main components: a bimetallic strip, an overload protector, and a manual reset switch. When an excessive current flows through the circuit, the bimetallic strip heats up and causes the overload protector to trip, thus interrupting the circuit. The main contacts open and current interruption is achieved.

The manual reset switch allows the breaker to be reset when the overload current condition no longer exists. When the switch is pressed, the contacts close and current flow resumes. This circuit breaker also features an adjustable current tripping range, making it suitable for domestic and commercial applications. It can be adjusted to meet specific electrical service requirements.

The IALHK11-1REC5R-39400-30 circuit breaker also features a single-adjustment mechanism that simplifies calibration of the trip-point current range. The calibration procedure is simple and fast, allowing users to quickly and accurately set the breaker’s operating current range. The ability to quickly and precisely adjust the settings makes the breaker extremely versatile and well-suited for a variety of applications.

Conclusion

The IALHK11-1REC5R-39400-30 circuit breaker is an extremely reliable and versatile electrical protection device suitable for a wide range of industrial and commercial applications. The breaker is designed to protect electrical systems and components from overloads and short circuits. Its adjustable current tripping range and quick calibration mechanism make it highly adjustable and reliable. This circuit breaker is a great choice for ensuring the safety and protection of electrical systems.
