Their Unique design features offer installers the ability to access 221’s operating levers, even after installation. Carriers are open on one side, allowing conductors to be conveniently connected and removed before or after insertion. Benefits also include:
• Horizontal or vertical mounting on DIN-rail or screw onto flat surfaces
• Front-facing side remains open for all four mounting options
• Miniature mounting clamps ensure that connectors never slip out of the carrier
221-500 carriers offer effortless installation and are compliant with international VDE standards. Installation is always tool-free and a spot for self-adhesive marking provides a clear overview of wire assignment in the cabinet – even if the original installation has been modified or expanded.
