CLR Success story: Actuator for differential automatic resetting

CLR designs a new tailored gear motor for a differential automatic resetting system. A handy solution when we are not at home. Discover how it works here.

CLR has a long track record in the development of displacement mechanisms in the electromechanical sector. In the success story we show you one of our latest projects on this field: an actuator for differential automatic resetting and thermal-magnetic circuit breakers. This solution comes very handy when there is a power outage and we are not home to manually turn the power back on.

What were the main challenges of this project?

A company specialised in the design and production of electronic equipment, needed to add a reliable gear motor in a reduced DIN rail along with the rest of the components of the consumer unit.

On the other hand, CLR engineers had to keep in mind the significant regulatory limitations governing electronic equipment control, in addition to complying with safety requirements set forth by the EU on the subject.

How does the differential resetting work?

After the differential circuit breaker is triggered, the switch is reconnected following a 3 to 6-reconnection sequence. In case reconnection is not feasible, the differential remains locked in ‘triggered’ mode until manually or remotely reset.

On a more technical note, the system includes two inputs for activation via external voltage-free signals. In this manner, the signals command the opening (input O) and subsequent closing or reconnection of the automatic circuit breaker (input I) where CLR’s gear motor is located. Thanks to this, these thermal-magnetic circuit breakers offer protection against short-circuits and overloads, as well as working as a remote cut-off device.

Finally, the engineering department developed a solution tailored to their various home thermal-magnetic circuit breaker models.
