Phase Sequence 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 casesApplicationFor 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-PS13 phase 3 or 4 wireTypical ApplicationsThe M200-PS1 provides phase and phase sequence / failure protection. Used to ensure the sequence is correct when connecting 3 phase loads. With an incorrect phase sequence the relay will start to de-energise, preventing the starting of incorrectly connected machinery. The relay will also trip if there is a phase loss and can therefore be used as a phase failure relay.If regenerated voltage voltage is present in the open phase the M200-PB1 or M200-PB2 should be used. The red LED ?On? indicates phase sequence incorrect and relay is de-energised.. The green LED ?On? indicates phase sequence correct and relay is energised.Technical SpecificationsINPUTRated value Un57.8 < 500V ±25%Frequency50 / 60 / 400HzBurden<3VAOverload1.5 x continuous 2 x Un 3 secondsSETPOINTNot adjustableAUXILIARYSelf PoweredWEIGHT&CASEApprox 0.4kg. 55mm caseOrderingProduct CodeInput UnFreqOptionsM200-PS1415V50HzCal 35CConnection Diagrams
