IULK1111-35788-1

Circuit breakers come in two forms, hydraulic-magnetic and electronic-thermal. IULK1111-35788-1 is an example of the former, known as a low voltage, hydraulic-magnetic circuit breaker. These circuit breakers generally use the same principles to break electrical circuits, but they differ in the details of their design and operation.

Application Field

IULK1111-35788-1 is suitable for household distribution systems, power stations, and low voltage industrial distribution systems. It is also used in applications such as single-pole breakers, two-pole breakers, and three-pole breakers where a higher current rating is required than what is available for the single-pole breaker. The breaker has a rated operational voltage of 230 Vac and rated current of 36AAC.

Working Principle

Hydraulic-magnetic circuit breakers such as the IULK1111-35788-1 work by using hydraulic energy to open the contacts and close them again when the current drops below a predetermined level. These breakers use a hydraulic system, with pressured oil being held in check by a magnetic field. When an overload or short circuit occurs, the magnetic field collapses, which causes the oil pressure to increase and forces the contacts of the breaker closed. When the current returns to normal, the oil pressure drops and the contacts are reopened.

To ensure reliable and safe operation, the IULK1111-35788-1 must be carefully installed, and the manufacturers’ instructions followed closely. This includes installing the breaker in an appropriate environment, derating where necessary, and performing regular maintenance and testing.
