Circuit breakers are electrical devices used to protect electrical circuits, power systems, and electrical and electronic equipment from damage due to overload or short circuits. The most common type of circuit breaker is the IELH111-35277-1-V, which is an AC circuit breaker with a voltage rating of 600VAC and an ampere rating of 100A.

Application field

The IELH111-35277-1-V circuit breaker is mainly used in residential and commercial buildings, such as offices and homes, to protect electrical circuits from overloads and short circuits, and to help maintain the continuity of electrical power and reduce the risk of fire hazards. Specifically, the IELH111-35277-1-V is used for branch circuit protection in new or existing installations that call for a 120/240 volt, single phase, three-wire system. It is also used in industrial and commercial applications, where a high-voltage circuit breaker is required.

Working principle

The IELH111-35277-1-V circuit breaker consists of an operating mechanism and a switching device. The working principle of the circuit breaker is based on the principle of induction. When an overload or a short circuit occurs, an electromagnet with a coil wound around it is energized. This increases the magnetic field produced by the coil, which attracts the circuit breaker’s main contacts, thereby opening the circuit and preventing a surge of electricity. When the overload or short circuit is cleared, the contacts return to their original position, allowing the current to flow through the circuit again.

The IELH111-35277-1-V also has a trip mechanism, which allows it to trip the breaker even when the main contacts are not opened. The trip mechanism is activated by a thermal or magnetic element, depending on the type of circuit breaker. The thermal element is designed to detect a sudden rise in temperature, while the magnetic element is designed to detect a sudden change in the magnetic field produced by a current. Both the trip mechanism and the main contacts open the circuit breaker circuit when the triggering elements are activated, thus providing protection against overloads and short circuits.

The IELH111-35277-1-V also comes with an adjustable setting, which allows you to manually select the correct setpoint for a particular circuit. This helps to ensure that the circuit breaker trips when the current or temperature rises above the desired level, thus providing the necessary protection.

The IELH111-35277-1-V circuit breaker is a reliable and economical solution for protecting electrical circuits from overloading and shorting out. It is easy to install, operate and maintain, and provides a reliable protection against overcurrents, short circuits and electrical fires. It is also able to automatically trip and reset itself, saving time and money. The IELH111-35277-1-V is an effective and economical solution for protecting electrical circuits from overloading and shorting out.
