These exclusive, easy-to-use cables with plug retention save space and ensure the secure connection of IT equipment to rack-mounted PDUs. The cables can be used with any standard IEC socket or power inlet; the locking mechanism only engages when used with APC Rack PDUs from the AP8000 series or IT equipment with corresponding integrated inlets. The plug retention protects against accidental disconnection of cables and thus against an interruption of the power supply.
