Circuit Breakers

IULNK1-31269-14 is a low voltage circuit breaker manufactured by IULNK. It is a fixed type three pole circuit breaker with a rated Current of 10A and a rated voltage of 690V; and it is mainly used to protect distribution systems or lines in a building, providing good electrical organization and protection. Moreover, IULNK1-31269-14 offers protection against overload and short circuit. The design and function of the IULNK1-31269-14 protect the circuit or electrical distribution system by breaking the circuit whenever it detects an overload or short circuit conditions.

Application Field

IULNK1-31269-14 is mainly used in industrial and civil applications. In industrial applications, the three poles of the breaker are suitable for three-phase motors, main distribution, process control, lighting control, and other equipment. Meanwhile, in civil applications, such as homes, offices, schools, and shopping malls, the breaker is mainly used as short-circuit and overload protection for AC circuit and illumination circuit.

Working Principle

IULNK1-31269-14 operates on a trip release mode which enable it to detect overload and short circuit faults. The principle operation involves the movement of the main contacts of the of the circuit breaker. The main function of the breaker is to break the circuit in the event of a fault. It is designed with two main components; the trip coil and the trip release mechanism.

The trip coil is designed to react to any electrical overload or short circuit conditions. The overloading or short circuiting of the circuit generates heat that causes the release of a magnetic armature. The release of the armature allows the tripping mechanism to actuate and break or trip the circuit. The trip release mechanism is designed to break the circuit upon the actuation of the trip coil. The mechanism automatically trips after a specific time, thus providing automated and timely protection during a fault.

In short, IULNK1-31269-14 is a low voltage three pole circuit breaker which provides protection against overload and short circuit. It is mainly used in industrial and civil applications. The circuit breaker operates on a trip release mode which enable the breaker to detect overload and short circuit conditions.
