Technical products for MV/LV electrical infrastructure.
Protection RelaySepam G Series
When MV generator protection is needed — including loss of excitation, reverse power, ROCOF disconnection and differential protection — the Sepam G Series is what we specify. Model G40 covers the core generator protection suite while G82 adds ROCOF disconnection and G87/G88 provide machine differential protection for larger generating units.
Protection RelayPowerLogic P3U
When a single relay must handle feeder, motor or transformer protection in the same hardware platform — the P3U is what we specify. It combines all P3 functions in one universal device, reducing spare parts and simplifying projects where multiple protection applications are needed across one installation.
Protection RelayPowerLogic P5x30
When a demanding MV application requires withdrawable design, built-in arc flash protection, dual redundant Ethernet and 10-minute recovery after relay replacement — the P5x30 is what we specify. It covers feeder, motor and transformer differential protection with LPCT/LPVT inputs, ZigBee wireless condition monitoring and up to 40 digital inputs in a single modular platform.
Protection RelayPowerLogic P7
When a substation or large industrial facility requires the highest level of protection, control and automation — including virtualization readiness, nine communication protocols and predictive asset monitoring — the P7 is what we specify. It is Schneider Electric's flagship protection platform, designed for the most complex feeder, motor, transformer and generator applications.
Protection RelaySepam M Series
When MV motor protection is needed — including thermal overload, locked rotor, starts per hour, negative sequence and RTD temperature monitoring — the Sepam M Series is what we specify. Model M20 covers essential motor protection for straightforward applications while M41 and M87 add directional functions and differential protection for larger or more critical motors.
Protection RelayPowerLogic P3M
When MV motor protection is needed with thermal overload, rotor jam, unbalance and underspeed detection — the P3M is what we specify. It protects against all standard motor fault conditions and integrates with IEC 61850 for SCADA reporting of motor status, start counts and running hours.
Protection RelayRET615
When MV power transformer protection is needed — including biased differential, restricted earth fault, overfluxing and Buchholz/thermostat monitoring — the RET615 is what we specify. It is designed for two-winding power transformers, unit and step-up transformers and generator-transformer blocks, with IEC 61850 Ethernet communication and PCM600 tool support.
Protection RelayREX615
When a single relay must cover both feeder and motor protection in the same hardware — reducing spare parts and simplifying engineering for mixed MV installations — the REX615 is what we specify. It combines feeder and motor protection functions in one IEC 61850-enabled relay, configured via PCM600 for either application without hardware changes.
Protection RelayREF615 / REF601
When MV feeder protection is needed across utility substations and industrial power systems — from cost-optimised entry-level to advanced IEC 61850 Ethernet-enabled configurations — the ABB REF series is what we specify. REF601 covers essential overcurrent protection for straightforward applications, while REF615 adds directional earth fault, arc flash detection, IEC 61850 communication and full PCM600 engineering tool integration.
Protection RelayPowerLogic P5x20
When a demanding MV application requires LPCT/LPVT sensor support, IEC 61850 Ethernet communication and a compact non-withdrawable form factor — the P5x20 is what we specify. It covers universal feeder and voltage protection with the same modular communication architecture as the P5x30 but without arc flash detection.
Protection RelayRelion 630 Series
When a substation or large industrial facility requires advanced protection, control and automation with high I/O counts, multiple bay applications and full IEC 61850 substation automation — the Relion 630 series is what we specify. It covers feeder (REF630), transformer (RET630), motor (REM630) and busbar (REB630) applications in a scalable withdrawable platform with redundant Ethernet.
Protection RelayREM615 / REM601
When MV motor protection is needed — including thermal overload, locked rotor, starts per hour, unbalance and RTD temperature monitoring — the ABB REM series is what we specify. REM601 covers essential motor protection at low cost, while REM615 adds directional earth fault, IEC 61850 Ethernet communication and machine differential protection for larger or more critical motors.
Protection RelayPowerLogic P1F
When MV feeder overcurrent protection is needed at low cost — especially for retrofit of electromechanical relays in utility and industrial substations — the P1F is what we specify. It covers ANSI 50/51/50N/51N functions, communicates via RS485 with IEC 60870-5-103 or Modbus, and fits in a compact flush-mount case with IP54 protection.
Protection RelayRED615
When fast and selective protection of MV cable or overhead line sections is required — especially where distance protection is not applicable or where high-speed tripping is critical — the RED615 is what we specify. It provides current differential protection for two-terminal lines with Ethernet-based peer-to-peer communication using IEC 61850 GOOSE messaging.
Protection RelayPowerLogic P1V
When MV voltage and frequency protection is needed alongside basic overcurrent — the P1V is what we specify. It covers under/overvoltage, under/overfrequency and neutral displacement functions, communicates via RS485, and shares the same compact flush-mount form factor as the P1F.
Protection RelayPowerLogic P3F
When MV feeder protection requires advanced functions — including directional earth fault, arc flash detection, LPCT/LPVT sensor inputs and IEC 61850 Ethernet communication — the P3F is what we specify. It covers all standard feeder ANSI functions and supports built-in virtual injection testing to reduce commissioning time.
Protection RelaySepam S Series
When MV feeder and substation protection is needed across a wide range of network types — from simple radial overcurrent to directional earth fault and full voltage/frequency monitoring — the Sepam S Series is what we specify. Models S20 through S84 cover basic overcurrent (S20), directional protection (S40/S41/S42) and advanced substation functions (S80/S81/S82/S84), all in the same proven Sepam platform.
Protection RelaySepam B Series
When voltage and frequency protection is needed for MV busbars — or when capacitor bank unbalance protection is required — the Sepam B Series is what we specify. Models B21 and B22 provide bus voltage and frequency monitoring for incomer and bus coupler applications, B80 covers dual busbar systems and B83 protects capacitor banks against unbalance and overload.
Protection RelaySepam T Series
When transformer protection is needed — from simple overcurrent on small distribution transformers to biased differential protection on large power transformers — the Sepam T Series is what we specify. Models T20 through T87 cover basic transformer overcurrent (T20), directional functions (T40/T42) and full differential protection with restricted earth fault (T87).
