The IULHK1112-36221-1 is an a circuit breaker, specifically designed for protecting electrical circuits against overloads and short circuits. The circuit breaker is capable of separating from the main supply and preventing an overload condition.

The circuit breaker works by monitoring current supplied to an electrical circuit. When the current exceeds a predetermined maximum, the circuit breaker trips, switching off the circuit and preventing further damage. In some cases, the trip may not be instantaneous, allowing the ?overload? current to flow for some time before the circuit breaker trips.

The IULHK1112-36221-1 is designed for applications requiring the reliable protection of both AC and DC circuits. It is capable of detecting and responding to both over-current and short circuit conditions. The circuit breaker is designed to be mounted on any standard DIN rail or panel for easy installation and maintenance.

The IULHK1112-36221-1 features a positive locking latch which ensures that the circuit breaker is securely locked in place after it has been manually switched off. This prevents the circuit breaker from being accidentally switched back on without proper authorization. The circuit breaker is also approved for use in hazardous locations, making it an ideal choice for industrial and commercial applications.

In terms of working principle, the IULHK1112-36221-1 circuit breaker uses an electromagnetic current sensor to measure current flowing in the protected circuit. This sensor is connected to a thermal switch, which trips the circuit breaker in the event of an overload or short circuit. Upon tripping, the circuit breaker is reset by manual means.

Additionally, the IULHK1112-36221-1 is fitted with a surge suppressor, which prevents downstream components from suffering serious damage caused by an inrush of current. This surge suppressor is adjustable, allowing users to tailor the protection to the requirements of their application.

In summary, the IULHK1112-36221-1 circuit breaker is an ideal solution for protecting both AC and DC circuits from overloads and short circuits. It features a positive-locking latch to ensure secure manual resetting, as well as a surge suppressor for protection against inrush currents. It is approved for use in hazardous locations and is easy to install and maintain.
