IULHK111-1REC4-71302-18 Circuit Protection

Circuit breakers are a type of switch that break an electrical circuit open in order to prevent a current overload or a short circuit from occurring. The IULHK111-1REC4-71302-18 circuit breaker is a molded case circuit breaker specifically designed for use in residential, commercial, and industrial applications. It is UL and CSA certified, and is rated for 10-125 A at 120/240 VAC.

This type of circuit breaker is designed to provide reliable protection against electrical shorts and overloads. It is constructed with two moveable contacts, known as the trip and control contacts. The trip contact is held closed by the contacts spring and the control contact is held closed by an electromagnetic coil.

When the current flowing through the IULHK111-1REC4-71302-18 circuit breaker reaches a predetermined level, the electromagnetic coil is energized and the trip contact opens. This opens the circuit, preventing any further current flow, which can then be used to reset the circuit breaker in case of an overload or short circuit.

Another use for this type of circuit breaker is for protecting motors from high currents. This type of circuit breaker stores energy from the motor when it is idle and releases it during operation. This allows the circuit breaker to react quickly and shut off the current in the event of an overcurrent.

The IULHK111-1REC4-71302-18 circuit breaker also provides protection against arcing by using arc-detection devices. These devices detect arcing by sensing changes in the electric field. When an arc is detected, the circuit breaker is immediately opened to prevent any further arcing.

The IULHK111-1REC4-71302-18 circuit breaker is a reliable and efficient device for providing protection against electrical overloads and shorts. It is designed to be used in residential, commercial, and industrial applications, and provides fast reaction times in order to avoid any further damage or arcing to electrical circuitry.
