Current limiting Voltage Sensitive Relays: This range have all the adjustment abilities as per the Pro Connect VSR.
These relays have built in current limiting, in a nutshell you can do whatever you want with them. If you overload them they simply switch off safely. The trick with a relay is not to open circuit when it is overloaded, but to remove the load. Then open circuit the relay within its rating.
With a current limiting VSR in an overload situation such as the example in the section above (Voltage Sensitive Relays) the 200A will surge through the relay for a split second (within the relay’s capability), then the built in current limiting device will see this overload and reduce the current from the dangerous 200A+ to a very safe 6A, the relay will then safely open circuit with a 6A load and not a 200A load, and so protect the relay and your installation. Once the high load demand has been removed then the relay is safe to re-engage and continue doing its job.
