Circuit breakers are important components of electrical systems, providing essential protection against overloads, short circuits, and other sources of potential harm to the system. One such device is the IEGHF66-34440-40B-V (hereafter referred to as the IEGHF), a 2-pole MCB that interrupts currents with ultimate breaking capacities (Icw) up to 40A and ultimate short-circuit capacities (Icm) of up to 10 kA. The IEGHF is suitable for use in both residential and commercial applications, and meets the requirements of EN 60898-1.

The IEGHF has many advantages over other circuit breakers, such as its low-cost, compact design and high breaking capacity. Additionally, the IEGHF is compliant with all relevant safety standards and is tested to LCIE VAC tests (Voltage Alternating Current Tests, issued by the Laboratoire Central des Industries Electricite). The IEGHF also has a unique patented TKD (Trigger-Kick-Delay) system which allows it to switch rapidly and reliably between energy levels, thereby protecting the system against surges and higher currents.

The working principle of the IEGHF circuit breaker is based upon the fact that when a high-voltage current passes through a magnetic field, it produces an electromagnetic force that moves a lever. This lever operates a contact inside the IEGHF which interrupts the current once the predetermined level has been reached. The IEGHF can sense when the current level has been exceeded and will automatically interrupt the current in order to protect the system.

The IEGHF can be used in a variety of applications, including residential and commercial power distribution systems, single-phase circuits, and installations where the load current may exceed the MCB\'s rated current value. The IEGHF is suitable for both AC and DC systems, as well as for systems powered by renewable energy sources such as wind and solar. The IEGHF has a wide short-circuit capacity, making it suitable for installations where the short-circuit current may be high.

The IEGHF has many advantages, including its low-cost design and high breaking capacity. It is also compliant with all relevant safety standards and is tested to meet LCIE VAC tests. Additionally, the IEGHF has a unique patented TKD system, which allows it to react quickly to energy level changes and protect the system accordingly. The IEGHF can be used in a variety of applications, making it a versatile and reliable circuit breaker for installations requiring protection against extreme currents.
