Built to ABB’s quality standards, this relay delivers reliable performance across diverse applications requiring auxiliary switching logic, interlocking, and control signal distribution.
Key Features
- DC 110–125V nominal coil voltage with stable switching characteristics
- 2 make contacts and 4 break contacts for flexible circuit configuration
- Plug-in design for quick installation and replacement
- Robust construction suitable for panel mounting and harsh industrial environments
- Compliant with international relay standards for electrical safety and reliability
Technical Specifications
- Coil Voltage: DC 110–125V
- Contact Configuration: 2 make (NO) + 4 break (NC)
- Relay Type: Auxiliary relay (all-or-nothing)
- Mounting: Plug-in module (DIN-style rail or socket mount)
- Operating Temperature Range: –5 °C to +55 °C (typical for ABB RXMM series)
- Coil Resistance: Approx. 3000–3500 Ω (typical for 110V DC winding)
- Contact Material: Silver or silver alloy (standard for ABB relays)
Typical Applications
The RXMM 1 RK 214 005-AN is commonly deployed in:
- Control and interlocking circuits in switchgear and motor control centers
- Signal distribution in substation protection and automation systems
- Industrial logic switching where multiple break contacts are required
- Backup and redundancy circuits in critical power systems
- General-purpose relay logic panels and supervisory control modules
Compatibility & Replacements
The RK 214 005-AN fits the ABB RXMM 1 relay socket interface, standard across ABB’s auxiliary relay product line. Other variants in the RXMM 1 series (such as RK214001, RK214002, RK214003, RK214004) offer different voltage ratings (24V, 48V, 60V DC) and contact arrangements. When specifying replacement relays, verify coil voltage and contact count to ensure compatibility with your existing wiring and control logic. ABB relays within the same series are mechanically interchangeable but electrically distinct by model number.
