The REF610C55LCNR is a feeder protection relay manufactured by ABB.It is primarily used for bay protection of incoming and outgoing lines in medium-voltage distribution networks.It can also be used for backup protection of motors,transformers,and generators in industrial applications and power distribution networks.The following are product details:
Protection Functions
Overcurrent Protection:Overcurrent protection with definite or inverse time characteristics,time-limited current quick-trip protection with definite time or instantaneous characteristics,and current quick-trip protection with definite time or instantaneous characteristics.
Zero-sequence Current Protection:Zero-sequence Current Stage II protection with definite time,inverse time,or instantaneous characteristics,and Zero-sequence Current Stage I protection with definite time or instantaneous characteristics.
Other Protection:Current unbalance protection,cable feeder thermal overload protection,arc protection,circuit breaker failure protection,etc.Technical Parameters
Power Supply:Auxiliary power supply types include REF 610xxHxxx and REF 610xxLxxx,with rated voltages of AC 100/110/120/220/240V and DC 110/125/220/250V,24/48/60V.Auxiliary power consumption is less than 9W/13W in static/operating conditions.
Inputs and Outputs:Four precision AC current inputs with a user-selectable 50/60Hz rated frequency;three normally open heavy-duty output contacts;two normally open/normally closed signal output contacts,which can be increased to five normally open/normally closed signal output contacts upon request;and two electrically isolated digital input contacts,which can be increased to five electrically isolated digital input contacts upon request.Fault Recording:Recording time is 5 seconds(800Hz sampling rate),can be triggered by one or more internal or external signals,and can record four analog channels and up to eight user-selectable digital channels.The sampling rate is adjustable.
Communication Interface:Front panel communication options include wireless or cable.The backplane communication module supports plastic fiber,composite fiber(plastic and glass fiber),or twisted pair via RS-485.Supported protocols include SPA-bus,IEC 60870-5-103,or Modbus(RTU and ASCII modes).A DNP 3.0 backplane communication module is also available for communication with the system.It uses an RS-485 port and the DNP 3.0 protocol.Human-Machine Interface:Equipped with an LCD with text display and operational buttons,it features eight customizable LEDs.It displays relay operation information in either IEC or ANSI format,supports multiple languages,and offers user-selectable password protection for the HMI.It can display primary and demand values.
Physical Characteristics:Width 177mm,Height 177mm(4U),Depth 149.3mm.Relay weight approximately 3.5kg,plug-in weight approximately 1.8kg.
