Circuit Breakers are electrical components that can break an electric circuit either automatically or manually. They are typically used to protect electrical systems from hazardous over current events such as power overloads. This article will focus on a specific type of circuit breaker - the IEGHS113-27981-2-V. It will discuss its application field and working principle.

The IEGHS113-27981-2-V is a rapid acting thermal-magnetic circuit breaker that is designed for use in protection circuits of type AC 15A, AC 50/60 Hz. It is suitable for use in Industrial Automation and Control systems, Motor Control centers, and Power Distribution systems. This breaker also meets the specifications of UL 1077 Standard for Supplementary Protectors.

The IEGHS113-27981-2-V has a trip time of less than 5 ms, making it suitable for fast over current protection applications. It is rated for use with alternating currents of 15A, and direct current of 12A. This particular type of breaker is often used in high current loads where speed of response is highly important.

The working principle of the IEGHS113-27981-2-V circuit breaker is based on the thermal-magnetic effect. It features two internal components, the thermal element and the magnetic element. The thermal element is made up of a bi-metal strip that bends when exposed to heat. This allows it to open the circuit when its temperature is raised by a sustained current overload. The magnetic element is made up of a solenoid and an armature. When a certain current limit is exceeded, the armature is pulled inwards by the electromagnet, which results in the breaker tripping. The two elements work together to provide fast and reliable protection during over current events.

Overall, the IEGHS113-27981-2-V is a rapid acting thermal-magnetic circuit breaker designed primarily for fast over current protection applications. It meets the specifications of UL 1077 Standard and is suitable for use in industrial automation and power distribution systems. Its working principle is based on the thermal-magnetic effect which results in the two elements, the thermal element and the magnetic element, working together to provide fast and reliable protection during over current events.
