What’s an official definition you ask? It might sound like a complex concept, but the Manual Reset Relay is actually quite simple. To put it plainly, a Manual Reset Relay (MRR) is an electronic device that allows a user to manually reset any type of electrical circuit. This can be used in industrial applications or any time when it becomes necessary to cut off a power supply to a specific area and then be able to restore it at the press of a button. Put simply, the MRR acts as the critical link between technician and electrical system and can make all the difference in getting that very important job done right!
