2204R, 2206R and 2216R Push-in PCB Power Terminal Blocks
Description
Push-in power connections for PCBs
The 2204R, 2206R and 2216R terminals combine front wire entry with spring connections and top operating levers. Their 5mm, 7.5mm and 10mm pitches support different current ratings, conductor sizes and solder-pin arrangements. Each model has one connection level and 2–24 positions.
