The WAGO 280-837 3-Conductor Terminal Block is a DIN-rail-mounted ground terminal designed for safe and organized wiring in industrial control systems. It features WAGO’s CAGE CLAMP® spring connection technology, which allows fast, tool-free wiring of solid and ferruled conductors. This terminal block supports wire sizes from 12 to 28 AWG (0.08 to 2.5 mm²), making it suitable for a wide range of applications.
The unit is built for DIN-35 rail mounting (35 x 15 and 35 x 7.5 mm) and includes a center marking slot for easy identification. Its green-yellow housing clearly indicates ground connection, helping maintain safety and compliance in electrical panels. The compact 5 mm width saves space while still offering reliable performance.
Made from flame-retardant polyamide (PA66), the terminal block is RoHS3 compliant and meets industrial standards for durability and insulation. It’s ideal for grounding tasks in automation systems, switchgear, and distribution panels where secure and efficient wiring is essential.
