The 2V76 series relay is a single phase protection class AC voltage relay. It may be configured for under or over voltage operation & includes a filter for rejection of third harmonics for neutral displacement applications, which may be switched in or out of circuit. A definite time delay element is included which is initiated by the voltage detection circuit & drives the time delayed output contacts. Voltage & time settings are fully adjustable using DIL switches readily accessible on the front panel of the relay & provide a high level of repeatability & accuracy. Visual indication of an output relay operation is provided by a non volatile LED indicator which may be hand or remotely reset.
