It carries 1 watchdog and 5 outputs, plus 1/5 A CT inputs for phase and residual current and a 100 V/110 V VT voltage input. The relay includes an LCD 128 x 64 pixel display with single-line diagram, embedded HTTP server, and conformal coating for harsh environments. It is certified to IEC standards. ## Comparison with REL52011 Compared to the REL52011, the REL52015 draws double the power (48.0 W vs 24.0 W) and operates at a fixed 230 V supply versus the REL52011's 48 V. The REL52015 uses ring-lug CT terminals, while the REL52011 uses pin terminals for CT connections. The operating threshold is 110...230 V AC/DC on the REL52015 versus 24...230 V AC/DC on the REL52011.","metaTitle":"Schneider REL52015 PowerLogic P3 protection relay, 48.0 W, 230 V","metaDescription":"Schneider REL52015 PowerLogic P3 protection relay: 48.0 W, 230 V, IP54, 1 watchdog + 5 outputs, 1/5 A CT inputs, LCD display, IEC standards.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["General Purpose Relays"],"specifications":{"Depth":"205 mm","Width":"170 mm","Height":"169.5 mm","Standards":"IEC","Web server":"Embedded HTTP server","Display type":"LCD 128 x 64 pixels with single line diagram","Power Supply":"48...230 V AC/DC","Cybersecurity":"Password protection Port hardening","Number of key":"2 customizable","Software name":"EcoStruxure Power Device ESetup Easergy Pro","lifecycle_stage":"current","Local signalling":"4 LEDs 8 LEDs programmable","Logs And Records":"Event recording Disturbance recording Tripping context","Measuring Inputs":": 1/5 A CT phase current 3 : 1/5 A CT residual current 1 : 100 V/110 V VT voltage 1","Range of product":"PowerLogic P3","Control Functions":"Switchgear control and monitoring Programmable switchgear interlocking Local control on single-line diagram Local control with I/O keys Local/remote control 2 function keys Mobile application with Easergy SmartApp Web-server Programmable logic","Number of sensors":"0 temperature sensor(s) 0 arc sensor(s)","Product Reference":"P3U20-6AAA2ACAA","Relative humidity":"0...95 %, without condensation","Relay application":"Universal","Climatic Withstand":"Exposure to dry heat Bb tests conforming to EN/IEC 60068-2-2 Exposure to cold Ad tests conforming to EN/IEC 60068-2-1 Exposure to damp heat in service Db tests conforming to EN/IEC 60068-2-30 Exposure to damp heat in service Cab tests conforming to EN/IEC 60068-2-78","Mounting case size":"20TE","Communication Ports":"USB port 1 front RJ45 2 rear","Operating threshold":"110...230 V AC/DC","Arc flash protection":"No","Monitoring Functions":"Trip circuit supervision 74 Circuit breaker monitoring Relay self-monitoring","Protection Functions":"Phase overcurrent 50/51 Earth fault overcurrent 50N/51N Directional earth fault 67N Transient earth fault 67NI Capacitor bank unbalance 51C Broken conductor 46 I2/I1 Cold load pick-up Switch ON to fault (SOTF) Breaker failure 50BF Recloser 79 Phase undercurrent 37 Excessive starting time, locked rotor 48/51LR Motor restart inhibition 66 Capacitor overvoltage 59C Negative sequence overcurrent 46 Earth fault overvoltage 59N Rate of change of frequency 81R Lockout relay 86 H2 detection 68H2 H5 detection 68H5 Programmable stages 99 Programmable curve","Protective treatment":"Conformal coating","Measurement Functions":"Current 3-phase Current zero sequence Current positive sequence Current negative sequence Current ratio of negative and positive Voltage zero sequence Earth fault reactance Frequency Current phasor diagram view Current 2nd, 15th harmonics with THD Condition monitoring CB wear","Mechanical robustness":"Vibrations (level: class II) conforming to IEC 60255-21-1 Vibrations: Fc conforming to IEC 60068-2-6 Shocks (level: class II) conforming to IEC 60255-21-2 Shocks: Ea conforming to IEC 60068-2-27 Seismic tests method A (level: class II) conforming to IEC 60255-21-3 Bumps (level: class II) conforming to IEC 60255-21-2 Bumps: Ea conforming to IEC 60068-2-27","Communication Protocols":"IEC 61850 ed. 1 IEC 61850 ed. 2 IEC 60870-5-101 DNP3 TCP Modbus TCP EtherNet/IP","Connections -
