Circuit breakers are designed to protect circuits, equipment, and people from the dangerous potentials caused by electrical overloads, short-circuits, and faults. IULDHK111-35860-15 is a type of circuit breaker. It has been developed to provide reliable power distribution and protection, in both new and legacy installations. In this article, we will discuss the applications and working principles of IULDHK111-35860-15.

Applications:

IULDHK111-35860-15 circuit breakers are suitable for use in industrial, commercial, and residential applications. The device is available in both single-pole and three-pole models, and in a wide range of current ratings. It is US and Canada-listed for interrupting short circuits, and can be used in both 120/240V and 277/480V circuits. It is also UL-listed for power distribution, overload, and short circuit protection. As it is designed for low-voltage applications, it can be used in individual outlets, as well as in branch circuit distribution panels. Additionally, the device can also be used as a motor disconnect switch.

Working Principle:

The working principle of IULDHK111-35860-15 circuit breakers is based on a thermal/magnetic switch sequence. The device includes an electromagnet and a bimetallic strip. When an overload occurs, the heat generated by the current passing through the bimetallic strip causes it to deform, allowing the contact plates to separate, and thus disrupt the circuit. The electromagnetic field created by the electromagnet attracts an internal movable armature, which pushes the contact plates against the bimetallic strip and closes the circuit. The device can also be manually reset, if required.

In addition to providing overload protection, the device also offers protection against short-circuits. When a short circuit occurs, the current passing through the electromagnet is greater than the current passing through the bimetallic strip. This activates the armature, and it forces the contact plates apart, cutting power to the circuit.

The IULDHK111-35860-15 circuit breaker is designed to provide reliable power distribution and protection in both existing and new installations. It offers overload and short-circuit protection, and can be used in both residential and commercial applications. Furthermore, it is UL-listed for safety, and is available in a wide range of current ratings.
