Circuit breakers are one of the most important components of electrical systems. They are used to protect equipment from electrical hazards such as short circuits, overloads, and lightning strikes. The IELHK1111-1-61-80.0-91-V is a specific type of circuit breaker used in industrial applications for high-current loads and processes.

The IELHK1111-1-61-80.0-91-V circuit breaker is an Intelligent Electronic Load break switch. This type of circuit breaker combines superior switching technology, innovative design, and advanced programmability to offer users a robust and reliable solution for industrial power distribution. It provides improved safety and performance for heavy loads and is suitable for applications such as capacitor banks, transformers, motors, rectifiers, and other equipment.

This circuit breaker operates on the principle of electromechanical interruption. When electrical current is applied to the breaker, mechanical actuators responsive to electric currents cause an arc to form across the contacts of the circuit breaker, interrupting the circuit. A protective arc gap is provided between the contacts to allow the current to be safely broken and discharged. To open the contacts and interrupt the circuit, the short-circuit force must be strong enough to break the arc. This is achieved using a magnetic field generated by the breaker’s coils and a vacuum interrupter.

The IELHK1111-1-61-80.0-91-V circuit breaker is designed to provide reliable protection of equipment from cyclic high current overloads and short circuits. It is suitable for 3-phase systems that operate at 690VAC and 50/60Hz, and features an adjustable thermal overload curve to help protect from overcurrents. It also features a three-pole design for greater flexibility and an inharmonious voltage trip. Additionally, the unit has a robust construction and is able to operate in temperatures between -60°C and +70°C.

The IELHK1111-1-61-80.0-91-V circuit breaker is an ideal solution for applications in the fields of industrial electricity distribution, power distribution systems, motor control, capacitor banks, and transformers. It is designed to provide superior protection to equipment and users, and its advanced features and programmability ensure reliability and performance in any application. The unit is also UL listed and certified for use in the USA and Canada.
