IULNK111-1REC4-63-60.0 Circuit Protection

Circuit breakers are designed to protect electric circuits from damage due to overcurrents, overvoltage, short circuits, ground faults, reverse power flow and other electrical hazards. The IULNK111-1 REC4-63-60.0 is a type of circuit breaker that is designed for residential applications.

Applications

IULNK111-1 REC4-63-60.0 circuit breakers are used to protect household circuits, commercial wiring, and industrial wiring from damage caused by overcurrent, short circuits, and other dangerous electrical situations. The breaker must be correctly sized for the circuit it is protecting, including taking into account the number of current-carrying conductors, the voltage, and the full-load current of the circuit. This ensures that the breaker will trip and protect the circuit at the correct amperage level, without causing loss of power due to an excessively high setting.

Working Principle

The IULNK111-1 REC4-63-60.0 circuit breaker has a three-pole, thermal-magnetic design. This means that the bimetal strip senses the heat of the current and the magnetic pull of the current to effectively trip the breaker at the correct amperage level. When an overcurrent condition is detected, the bimetal strip will deform due to the heat of the current and release the spring-loaded toggle latch, which in turn trips the trip handle and breaks the circuit.

The IULNK111-1 REC4-63-60.0 also features an adjustable current setting. This allows the user to set the amperage trip point of the breaker to the correct level for the circuit it is protecting. The settings are displayed on the breaker\'s rating plate, and the adjustable current setting can be adjusted with a screwdriver.

Once a circuit breaker has tripped, it must be manually reset. To do this, the reset lever or button on the breaker must be pushed or pulled. This will reset the breaker and allow the current to flow through the circuit again.

Conclusion

The IULNK111-1 REC4-63-60.0 circuit breaker is a type of circuit breaker designed for residential, commercial, and industrial applications. It has a three-pole, thermal-magnetic design, with an adjustable current setting and manual reset lever or button. This circuit breaker is designed to protect circuits from overcurrent, short circuit, and other dangerous electrical situations.
