GE (Vernova) RMS7 RMS70002369 10055957G1

Overview

GE RMS70002369 (10055957G1) is the solid-state electronic trip unit for GE Spectra RMS RMS7 series molded case circuit breaker (MCCB). RMS70002369 is the base part number, 10055957G1 is the style/assembly drawing number used for spare ordering and traceability. GE RMS70002369 is an end-of-life digital RMS sensing release, widely supplied as exchange spare for ANSI low voltage distribution switchgear overhaul and breaker replacement.

Features

GE RMS70002369 supports adjustable long-time overload, short-time delay and instantaneous short-circuit protection; selected variants add ground fault protection. It uses RMS true current calculation for accurate protection under distorted waveform loads such as VFD and UPS feeders. GE RMS70002369 is self-powered from the breaker built-in current transformers, so protection functions remain available even with no external control power supply. It has local adjustment dials or DIP switches to set pickup thresholds and time bands for selective coordination between upstream and downstream protective devices. GE RMS70002369 includes built-in self-diagnosis for CT loop failure and internal electronic anomaly to reduce nuisance tripping and blind protection points. It can be paired with breaker auxiliary switches to send trip and alarm status to SCADA and sequence-of-event logging systems. This trip unit is not a complete breaker; it must be installed inside the matched RMS7 frame with corresponding CT sensors. It complies with ANSI / UL standards for North American power distribution systems.

Specs

GE RMS70002369 platform: Spectra RMS RMS7 MCCB. Sensing type: True RMS digital sensing. Power supply: CT self-powered. Adjustment method: local dial / DIP setting. Protection functions depend on the specific bin of this unit: LI / LSI / LSIG options. Style drawing number: 10055957G1. GE RMS70002369 is widely supplied as service replacement spare for industrial, water treatment and data center ANSI MCCB maintenance.

Principle

GE RMS70002369 continuously samples phase current signals from the breaker integrated CTs and computes true RMS current value. The internal logic compares measured current against preset overload and short-circuit thresholds. When the current exceeds the configured setting, the trip unit triggers the breaker mechanical release mechanism to separate the main contacts and isolate the fault circuit. The trip event of GE RMS70002369 is signaled through breaker auxiliary contacts. RMS measurement technology avoids under-measurement caused by harmonic distortion common on modern non-linear loads.

Applications

GE RMS70002369 is deployed for main incoming, bus tie, pump, fan and large feeder protection in ANSI-spec industrial plants, commercial buildings, water treatment facilities and data center low voltage distribution switchgear. It is selected for spare inventory and breaker retrofit projects where legacy Spectra RMS selective protection is required.
