Description
The Emerson Network Power M307 Central Office Protector Panel is designed for use in
remote electronic cabinets such as Emerson’s MESA cabinets and for use in central office
applications which incorporate COSMIC mainframes. Its compact design measures 5.75
in. wide x 7.81 in. long x 1.12 in. deep and accepts industry standard 5-pin modules in a
10x10 pattern.
Made of high impact polycarbonate, the M307 block can be factory stubbed with
24-gauge or 22-gauge cable and connectorized with 710 or MS2 industry standard connectors for quick terminations to input and output cables. The M307 can also be supplied
with an integrated printed circuit board with connectorized back-plane to provide a
modular assembly.
The front-facing protector field allows testing through the protector modules with conventional test equipment. The rotating and snap-in design allows for quick and fool-proof
installation. The rear hood provides for secured cable strain relief and terminal protection.
Pair identification is provided on the front surface of the block. The ground bar provides
attachment for double ground lugs and there is a rear panel bracket for cable strain relief.
Application
The M307 protects personnel and equipment
from abnormal voltages and currents on
incoming cable pairs. It mounts on channels
equipped with plastic receptacles for
installation efficiency. The M307 is designed
for easy installation with bottom pivot and top
snap-in feature.
•Easy snap-on mount for assembly
