Reverse Power Protection Relay

DescriptionDIN rail mounting protection relays for use in single and three phase systems. Available in 55mm x 112mm or 100 x 112mm DIN rail cases.ApplicationFor over protection, under protection and combined under & over protection available in AC current AC voltage & frequency versions. Millivolt trip, DC voltage trip, Reverse Power, Phase sequence & Phase balance relays also available in our extensive range of protection relays.Selection GuideM200-RP1Single or 3 phase 4 wireM200-RP33 phase 3 wireTypical ApplicationsThe M200 reverse power relay is used to monitor the direction of power from A.C generators, if the current in the system being monitored is reversed, to a value greater than the customer adjustable preset limit the relay will energise. The adjustable trip point is 2% to 20% of input current. An adjustable time delay of 0 to 20 seconds is provided. Correct setting of the trip point and time delay, will ensure protection against motoring in the event of a generator failure and prevent tripping due to transients encountered during synchronisation. A red LED indicates the state of the relay and a green LED indicates the condition of the power supply.Technical SpecificationsINPUTRated value Un57.8< 500V ±25%Rated value InC.T. operated 1 or 5A or direct connected 0.2 to 10AFrequency50/60/400HzBurden<3VA voltage <0.5VA currentOverload1.5 x Un 2 x In continuous 2 x Un 10 x In for 3 secondsSETPOINTRepeatabilityBetter than 0.5% of full spanTime delayAdjustable 200mS to 20 secHysteresis1%AUXILIARYAll units self poweredWEIGHT&CASEApprox 0.6kg. 100mm caseProduct CodeIn InputUn InputFreqOptionsM200-RP31 Amp400 Volt50Hz5 sec T/DOptions1Adjustable time delay max 30 seconds2A.C.
