Product Description

• The WAGO 280-687 is a three-conductor protective earth terminal block designed to provide secure grounding connections in industrial electrical control panels, machinery, and electrical distribution equipment.
• Each terminal block features three CAGE CLAMP spring-pressure connection points, allowing multiple protective earth conductors to be connected to a common grounding potential.
• WAGO's CAGE CLAMP connection technology provides secure conductor retention without conventional screw-tightened wire connections, helping maintain reliable electrical contact in demanding industrial environments.
• Designed for standard 35 x 7.5 mm and 35 x 15 mm DIN rails, this terminal block features a compact 5 mm width, allowing organized grounding arrangements alongside compatible DIN rail terminal blocks.
• The green/yellow housing provides standardized visual identification for protective earth connections. The insulating body is manufactured from polyamide (PA66) with a UL 94 V-0 flammability rating.
• The terminal block supports conductor sizes from 0.08 mm² to 2.5 mm² (28–12 AWG) and features front-entry wiring with an 8–9 mm conductor stripping length.
• Suitable for industrial automation, electrical control cabinets, machinery wiring, protective earth terminal assemblies, and compatible marine electrical installations.
