Overview
The ABB RXSF 1 RK 271 019-AN is a general-purpose signal relay designed for DC control applications in power distribution and industrial automation. This reliable auxiliary relay delivers precise contact switching with integrated visual indication, making it ideal for protection circuits, intertrip logic, and remote monitoring in substation and control cabinet environments.
Key Features
- Automatic reset function—contacts reset to de-energized position when coil voltage is removed
- 2 make and 4 break contact configuration for flexible switching logic
- Red indicating flag shows relay state without external monitoring equipment
- High AC surge immunity permits use as intertrip and remote indicating relay
- Twin contact design for redundancy and signal integrity in critical circuits
- Compact form factor for dense control cabinet mounting
Technical Specifications
- Coil Voltage: DC 110–125 V
- Operating Range: 80–110% of rated voltage
- Contact Configuration: 2 make, 4 break
