GE RMS7 RMS70005769 Product Description

Overview

GE RMS7 RMS70005769 is presented as a legacy protective relay module associated with the CEE / GE RMS-7000 or RMS7 relay family. Public surplus and relay references identify the CEE RMS-7000 as a discontinued digital multicurve phase and earth overcurrent relay, with public ratings of 5 A, 600 V, 50 W and 50/60 Hz. The supplied part number RMS70005769 was not confirmed in a direct official GE or CEE datasheet; the description below conservively identifies the unit as an overcurrent or earth-fault protection relay spare and marks exact terminal, trip characteristic, auxiliary supply and contact data for verification.

Features

The RMS-7000 family is described as a digital multicurve relay for phase and earth overcurrent protection. Digital multicurve overcurrent relays typically provide selectable time-current characteristics, current input for phase and earth-fault monitoring, trip or alarm output contacts, and settings for pickup current, time delay or characteristic curve. Public CEE relay documents in the RMS family describe microprocessor-based overcurrent protection used to protect three-phase electrical networks against short-circuit and earth-fault conditions and designed to replace electromechanical overcurrent relays in existing switchgear.

Because the exact reference RMS70005769 was not confirmed in an official catalog, the following details remain unconfirmed for this specific unit: auxiliary supply voltage, rated current input, CT ratio, number of phase and earth-fault elements, selectable curves, trip contact rating and contact arrangement, binary inputs, communication or test facilities, front-panel indicators, terminal layout, enclosure or case style, operating temperature, and mounting method. Public RMS-7000 surplus data should be treated as family-level reference only, not as a verified rating for the supplied part number.

Principle

A phase and earth overcurrent relay monitors current supplied from current transformers in a three-phase feeder, motor, transformer, bus or line protection circuit. When phase current or residual earth current exceeds the configured pickup level, the relay applies the selected time-current characteristic and initiates a trip or alarm signal through its output contacts after the configured delay. The trip contact can operate a circuit breaker trip coil, shunt trip, alarm relay or protection indication circuit to isolate the faulted feeder.

For replacement of an existing RMS7 or RMS-7000 family relay, the original current transformer ratio, relay pickup setting, time-current curve, time delay, auxiliary supply, trip contact wiring, trip coil rating, earth-fault scheme and terminal arrangement must be identified before installation. Protection relays are safety-related switchgear devices; commissioning, testing and wiring should be performed by a qualified protection engineer using the original relay drawings, protection settings, test procedure and applicable safety isolation rules.

Applications

GE RMS7 RMS70005769 would be retained as a legacy overcurrent or earth-fault protection relay spare for existing low-voltage or medium-voltage switchgear, motor control centers, feeder panels, industrial distribution boards, motors, transformers, generators, process plants, utilities, marine or commercial power systems where the original RMS7 or CEE RMS-7000 relay is installed. It supports repair or refurbishment of legacy protection schemes rather than new design. In existing installations, the relay should be treated as a replacement spare only when the function, current input, auxiliary supply, setting group, contacts and terminal wiring match the original protection scheme.
