IULHK111-1REC4-62-25.0-A-01 circuit breakers form the basis for all modern electrical systems. Developed alongside Edison’s contributions to electrical lighting, the circuit breaker is a safety device designed to prevent fires from forming in overloaded circuits. Without these circuit breakers, the safety of our modern homes and workplaces would be compromised. This article will provide an overview of the IULHK111-1REC4-62-25.0-A-01’s application field and working principle.

Application Field

IULHK111-1REC4-62-25.0-A-01 circuit breakers are designed for industrial, commercial, and residential applications. It is suitable for use in electrical installations ranging from 250A to 6300A with a voltage of up to 1kV. It complies with IEC 60947-2 standards and is EPA recognized. It is ideal for higher power uses such as motor feeders, transformers, and lighting systems.

Working Principle

At the core of the IULHK111-1REC4-62-25.0-A-01 is the thermal-magnetic element. This element is made up of two main parts, the thermal part and the magnetic part. The thermal part works by sensing the heat generated by the current running through the circuit. As the current increases, the temperature of the element rises, which activates a bimetallic strip that eventually opens the contacts. At the same time, the magnetic part uses a solenoid coil to sense the amount of current being drawn from the circuit. When the current reaches the pre-set limit, an electromagnetic force is induced in the solenoid, lifting a plunger up, and opening the contacts.

An additional feature of the IULHK111-1REC4-62-25.0-A-01 is its short-circuit and overload trip indication. This indication is signaled when pick-up current is reached, using LED signals. A green light indicates normal operation, while an amber light indicates tripping due to short-circuit or overload. When the circuit is completely overloaded, a red light indicates alarm tripping, and action must be taken to restore it.

Conclusion

The IULHK111-1REC4-62-25.0-A-01 circuit breaker form the basis for all modern electrical systems. Its application field and working principle make it an ideal device for residential, industrial, and commercial applications. Its integrated thermal-magnetic element ensures safe and reliable operation along with short circuit and overload detection.
