Overview

The ABB RSMVE1 Remanence Relay, officially designated as RXMVE1 (Product ID: RK257005-AN), is engineered for use in demanding industrial and utility applications. This relay is designed to retain its switching state even after control power is removed, making it ideal for systems requiring memory-based signal retention. Moreover, its robust design and precise switching logic support automation, protection, and interlocking functions in high-voltage switchgear systems.

Manufactured in Sweden, the RSMVE1 features ABB’s proven electromechanical relay technology. It is widely used in legacy substation control panels, motor control centers, and automation cabinets. In addition, its compact form factor and long mechanical life make it suitable for retrofit projects and long-term infrastructure support.

Technical Data

Typical Applications

• Substation Control Panels: Used to retain breaker or disconnector status during control power loss.

• Industrial Automation Systems: Supports signal memory and interlocking in motor control centers and PLC cabinets.

• High-Voltage Switchgear: Ensures safe switching and signal retention in GIS and AIS systems.

• Legacy System Maintenance: Ideal for replacing older memory relays in ABB protection and control schemes.

• Railway and Transport Infrastructure: Used in signaling and control systems requiring persistent relay states.

For example, utilities and industrial operators have deployed RSMVE1 in 110 kV and 220 kV substations to maintain control logic during power interruptions. Additionally, its electromechanical design ensures high immunity to electromagnetic interference, making it suitable for environments with heavy electrical noise.
