IELHR111-26267-3-V

The IELHR111-26267-3-V (hereinafter referred to as IEL) is a type of circuit breaker designed for use in both residential and commercial applications. This circuit breaker is designed for use in a three-phase system, and it offers excellent protection for both the main and branch electrical loads. The IEL is a UL listed device that meets all of the UL 1076 standard requirements for resiliency and strength. The IEL offers many advantages over traditional circuit breakers. It is designed to be easy to install, provides enhanced safety features, and is dependable and reliable.

The working principle of IEL is based on the current and voltage sensing technology and the use of various types of control currents. The main components of the IEL include the voltage sensing circuit, the current sensing circuit, the stored energy tripping mechanism, and the breaker head. All of these components work together to provide reliable protection from dangerous overloads and faults, and to ensure that the circuit breaker performs at its best when it is needed most.

The IEL is designed to detect when there is too much current flowing through a circuit, or when there is a voltage imbalance in the circuit. If the current level surpasses the preset trip limit, or if the voltage imbalance is too different than the nominal value, then the IEL trips its internal breaker in order to stop the excess current or voltage from flowing. This process is commonly known as line impedance monitoring and is an important protection feature of the IEL that helps to prevent power surges and over-voltage conditions from damaging connected appliances or equipment.

Aside from its current and voltage sensing capabilities, the IEL also has the unique ability to store energy. This stored energy can be used to trip the breaker during an overload condition when the current exceeds the preset trip limit. This means that the IEL can be used to provide trip protection even in the absence of voltage, making it ideal for a variety of residential and commercial applications.

The IEL is a reliable and dependable circuit breaker that provides superior protection for both the main and branch electrical loads. By offering superior protection against dangerous overloads, short circuits, and other electrical faults, the IEL helps to ensure the safe operation of connected appliances and equipment. With its modern software and smart design, the IEL is an ideal device for many applications, including both residential and commercial applications.
