ABB CL2-520R Relay

ABB CL2-520R is a 22 mm compact LED pilot light designed for panel-mount signaling in industrial control systems. This red indicator lamp operates at 220 V DC and uses an integrated LED for reliable visibility in factory environments. The unit carries ABB order code 1SFA619403R5201 and belongs to the CL2 family of compact signaling devices, fitting standard 22 mm panel cutouts on control panels where space is at a premium. The CL2-520R is commonly used to visually signal the energized state of machines, relays, or control circuits, providing a quick, at-a-glance status cue for operators. As part of ABB’s CombiLine Compact lineup, it complements other CL2 signaling devices to help create clear, intuitive control panels without sacrificing reliability.
