Features 213 mm (8.4 in.) connector height with front-facing jumper and test elds 4 inch intervertical spacing when installed on 8 inch verticals - provides ample space for placing cross-connect (jumper) wires Slide access protector module eld with self-latching design Front and rear snap-through fanning strips Listed MPC Mainframe Connector (QCM486) 100-Pair Connector The mainframe connector is a miniature, main distributing frame (MDF), high-density connector for use on the vertical side of main distributing frames or on protector frames. The MPC Mainframe Connector terminates 100 outside plant pairs and provides voltage or voltage and current protection for the cen- tral of ce personnel, wiring and equipment. It consists of a heavy gauge metal frame with an integral mounting bracket, ame-retardant plastic bases for the protector module, cross-connect (jumper) and test elds. The cross-connect and test elds are easily accessed from the front of the block to minimize installation and maintenance time. The MPC Mainframe Connector may be ordered with either insulation displacement connectors (IDCs) or wire-wrap terminations on the cross-connect (jumper) side. It is also available with 22 or 24 AWG (0.64 or 0.50 mm) stub cable in various lengths or stubless if desired. The protector modules are installed on the side of the MPC Mainframe Connector. Bourns QMP-series solid-state and gas tube pro- tector modules are available for the MPC Mainframe Connector. The protector modules may be ordered separately or pre-installed in the connectors detent position ready for cutover with full protection assured. A full range of installation and test accessories are available to support the MPC Mainframe Connector.
