Description

The R66P25 series of indoor blocks offers protection for 25-pair in a compact, versatile,
and cost-effective unit. These blocks have the same mounting dimensions as a 66M150
block, and can be mounted on a wall, backboard, or 89-type bracket (Emerson R891
Series and R89B).

Standard network cable termination options are either quick-clips or a cable stub.
Customer premise equipment termination options are quick-clips or 50-position RJ21 con­nectors.

• Universal hold-down keeps

connectorized RJ21s mated

• Compact design is high density

and has the same mounting
dimensions as the standard
66M150

• Mounts on standard 89-type

brackets for dynamic allocation of
wires on wall- or frame-mounted
applications

• UL Listed to meet or exceed

documented performance levels

Unstripped solid 20 to 26-gauge (.4 to .8 mm) conductors can be easily terminated using
an industry standard 714-type punch-down tool (Emerson R714B). Each block is supplied
with an integral fanning strip molded on one side of the base, marked every five rows to
simplify pair identification.

Units may be ordered with or without factory-installed 5-pin protector modules. To order
the R66P25 with factory-installed protection, add selected Emerson protector module
catalog numbers (R3B1EJZ, 3GUVS, etc.) to the catalog number. The R66P25 series will
accept carbon, gas, or solid-state 5-pin protector modules. One module provides pro­tection for one pair, and each unit can accommodate 25 modules. Each R66P25 is also
supplied with a ground connector for a 6AWG solid copper wire.

Application

The R66P25 series of protected blocks for
indoor use provide protection, protection/
demarcation, and sneak current fuse pro­tection. Intended for utilization in small
businesses, multiple dwelling units (MDUs),
and medium-density commercial or industrial
buildings, the R66P25 series is used by regu­lated telcos, interconnects, and contractors.
