Circuit breakers are safety devices in electrical networks that interrupt the flow of electricity when electric currents reach unhealthy or dangerous levels. The IULDHK11-1-66-2.00-AB-91 is a low voltage circuit breaker that is used to protect overloads and short circuit faults in low voltage or residential installations. It can be mounted on walls or in electrical switchgears.

In terms of its design, the IULDHK11-1-66-2.00-AB-91 is quite compact, measuring 176 millimeters in width and 127 millimeters in depth, making it suitable for tight spaces. The breaker also features quick make-and-break contacts and easily adjustable contact gaps for better reliability and longer service life. The body of the breaker is made of sheets of stainless steel and the trip unit is designed to withstand high electrical loads.

The IULDHK11-1-66-2.00-AB-91 is designed with an adjustable trip setting range from 0.1 to 10A for overload protection, while the short circuit protection range is from 6 to 10KA. This range of trip settings makes the circuit breaker suitable for protecting electrical networks in many types of residential applications, including air conditioners, washing machines, and other appliances with varying electrical loads.

In addition, the IULDHK11-1-66-2.00-AB-91 circuit breaker has been designed to meet the safety requirements of EN 60947-2, meaning it is suitable for use in residential areas and other applications where safety is of paramount importance. The breaker is also UL certified to UL 489, and is CSA certified to CSA C22.2, No. 5.

The working principle of the IULDHK11-1-66-2.00-AB-91 circuit breaker is based on a thermal-magnetic release system. When an overload or short circuit occurs, the thermal mechanism starts working, sensing the temperature and tripping the breaker if the set temperature is reached. This helps protect the device and the circuit from potentially dangerous overloads and short circuits. The magnetic mechanism works in the same way, and acts as a backup to ensure that the breaker will trip even if the thermal mechanism fails.

The IULDHK11-1-66-2.00-AB-91 circuit breaker is a reliable and effective choice for protecting broad ranges of residential applications. Its combination of adjustable trip settings and thermal-magnetic protection allows it to respond quickly and reliably to overloads or short circuits, minimizing the damage to sensitive electrical equipment and networks and protecting people against electric shocks.
