Screwless spring-clamp ground blocks, designed to simplify installation and save time and labor, are available for stranded and solid wires from 22 – 8 AWG. Individual spring contact clamps are depressed to insert a wire by using a screwdriver. Once released, the spring clamp maintains a consistent, high pressure contact against the wire. Integral, heavy duty mounting springs firmly lock the blocks to the mounting track, and provide a vibration-proof grounding connection. Grounded spring clamp blocks are available with a 5mm to 8mm pitch. Voltage ratings are up to 800 V and current ratings are up to 41A. Please check the customer drawings or website for CSA, VDE, and UL approval.
