Overview

The ABB RXME1 Auxiliary Relay is a trusted component in control and protection circuits across industrial and utility sectors. Engineered for DC operation at 110–125V, it features two make contacts that provide reliable switching for signaling, tripping, and interlocking functions. Moreover, its compact design and robust electromechanical construction make it ideal for harsh environments and long-term operation.

Manufactured in Sweden, the RXME1 is part of ABB’s modular relay family and is widely used in substation automation, motor control centers, and switchgear panels. In addition, its low power consumption and high mechanical endurance ensure minimal maintenance and extended service life. Engineers rely on RXME1 for its consistent performance and seamless integration into both legacy and modern systems.

Technical Data

Typical Applications

• Substation Control Panels: RXME1 is used for signaling and interlocking in high-voltage substations.

• Industrial Automation Systems: Supports control logic in motor control centers and PLC cabinets.

• Switchgear Protection: Ensures safe tripping and status indication in GIS and AIS systems.

• Railway Signaling Systems: Provides reliable switching in transport infrastructure control circuits.

• Legacy System Maintenance: Ideal for replacing older auxiliary relays in ABB protection schemes.

For example, RXME1 has been deployed in 110 kV substations across Europe and Asia to support breaker control and fault signaling. Additionally, its compact footprint allows for easy integration into dense control panels without compromising performance.
