A circuit breaker is a device that is designed to protect electrical circuits from damage due to overcurrents, short circuits, and ground faults. Circuit breakers are found in homes, buildings, automobiles, aircraft, and other applications where large amounts of electricity are used. The IULHK112-2REC4R-21379-2 circuit breaker is one such device that is specifically designed for industrial applications.

The IULHK112-2REC4R-21379-2 circuit breaker can be used for applications ranging from 600V to 6600V AC, with interrupting ratings up to 100,000A RMS symmetrical. This device is designed to protect against overvoltage, overcurrent, short-circuits, and other potentially dangerous electrical conditions. The IULHK112-2REC4R-21379-2 is equipped with a built-in ground fault circuit interrupter (GFCI), which is used to detect and prevent dangerous electrical arcing due to ground faults. Additionally, the device comes with an arc-fault interrupter (AFI), which is designed to detect and prevent electrical arcing caused by faulty wiring and insulation.

The IULHK112-2REC4R-21379-2 circuit breaker is made up of three major components: a breaker mechanism, a sensing and arresting coil, and a trip relay. The breaker mechanism is responsible for physically cutting off the flow of electricity when it exceeds an acceptable level. This is accomplished by using an armature that is attached to a contactor, which creates an arc when the current exceeds the breaker\'s specified rating. The sensing and arresting coil is responsible for detecting overcurrents, short circuits, and ground faults. This is accomplished by sending an electric current through the coil, which then trips the relay, which opens the breaker contacts and breaks the circuit.

The IULHK112-2REC4R-21379-2 circuit breaker is designed to be robust and reliable, with a wide temperature range of -40°C to +140°C. Additionally, the breaker is relatively small and can fit into most standard hole patterns. It is designed to be installed in a number of environments, from outdoor system applications to indoor machine premises. The breaker is also designed to withstand multiple short-circuit operations without degrading its performance.

The IULHK112-2REC4R-21379-2 circuit breaker is the ideal choice for protecting large installations and critical industrial systems. It is reliable, energy efficient, and can effectively protect against overcurrents, short circuits, and ground faults. Additionally, it provides maximum safety and is designed to function in a wide range of temperatures.
