Introduction

Circuit breakers are indispensable components of virtually any electrical system or wiring installation. The IEGHM666-32738-6-V (hereinafter referred to as IEGHM) is one such circuit breaker, and has the capability to provide over current, over temperature, and short circuit protection to a variety of devices and circuits. In this article, we discuss the application fields and working principle of the IEGHM circuit breaker.

Application Fields

The IEGHM is designed to protect both AC and DC circuits, as well as circuits with various levels of voltage from 15 to 600 volts. As such, the IEGHM is ideally suited to commercial, industrial, and residential applications requiring single-phase or three phase protection. The IEGHM can even be used in mobile applications, such as automotive vehicles, boats, motor homes, and other off-road equipment.

Furthermore, the IEGHM has a wide range of use cases, including being employed to protect electric motors, air conditioners, distribution panels, HVAC systems, transformers, and other types of equipment. IEGHM circuit breakers are often used as the main power cut-off switch for a range of industrial machinery and devices, as well as in building distribution systems. All of these use-cases make the IEGHM a versatile and cost-effective solution for protecting a range of applications.

Working Principle

IEGHM circuit breakers are designed to open the circuit on the detection of an increase in current, temperature, or potential above the pre-set levels. The circuit breakers are fitted with a bimetallic strip which detects any rapid changes in temperature, potentially indicating an overload. When an overload is detected, the bimetallic strip causes a contact bridge to open, disconnecting the load from the mains power supply.

The IEGHM circuit breaker also has an electromagnet which detects overloads and trips the breaker. This electromagnet responds to increases in current that surpass the pre-set overload level. The electromagnet is in series with the contact bridge, which forces it open when the electromagnet triggers.

The IEGHM circuit breaker also has an on-off switch which manually turns the breaker on or off. In cases where the load is small or the current drop does not reach the overload-level, the trip/reset mechanism of the circuit breaker can be manually operated.

Conclusion

The IEGHM circuit breaker is a reliable and versatile solution for protecting a range of AC and DC applications. Its ability to detect a wide range of current and temperature levels makes it suitable for commercial, industrial, and residential uses. The IEGHM\'s bimetallic strip and electromagnet are designed to detect overloads quickly, tripping the breaker and Disconnecting the device from mains power. The IEGHM also has an on-off switch which manually turns the breaker on or off, providing further control over the circuit.
