As the core component of the electrical control system, circuit breakers play an important role in the safety of electrical equipment and power grids. The IELHK111-33159-80-V circuit breaker is a kind of intelligent air-break miniature circuit breaker in the low-voltage power distribution industry. It is widely used in commercial buildings, residential buildings, power plants and other places, and it is mainly used to protect power grids and electrical equipment from overload, short circuit and other faults.

The IELHK111-33159-80-V Air-break Miniature Circuit Breaker is a type of three-phase breaker developed based on IEC/EN 60898-1:2015 "Miniature circuit breakers and residual current devices for household and similar applications." The design of this type of circuit breaker is based on the principle of direct breaking of the main circuit current, which is composed of mains, tripping coil and contacts. An electromagnetic force will be generated by a magnetic core and coil when the mains current exceeds the rated value or a short circuit occurs, which will allow the plunger on the tripping coil to move. The actuator in turn drives the main contacts, which will then open the main circuit and protect the circuit from further damage and overloading.

The rated current of the IELHK111-33159-80-V Circuit breaker is 80A, and the nominal voltage is AC 230/400V. The intelligent pole structure enables the circuit breaker to be compact in size and lightweight in weight. The arc extinguishing mode of the breaker is based on air-break technology. It has multiple functions, such as overload protection, short-circuit protection, under-voltage protection, leakage protection and over-voltage protection. It also has advanced safety features such as flame-retardant protection, overload current monitoring, and indicators.

Compared with traditional circuit breakers, the IELHK111-33159-80-V circuit breaker has the advantages of intelligent control, small size and light weight, easy installation, friendly user interface, simple operation, stable performance and reliable quality. The circuit breaker can be used in both indoor and outdoor environments, and it can adapt to harsh environmental conditions. It is widely used in buildings, factories, and other places to meet the needs of users in the low-voltage power distribution industry.
