Features, Benefits and Functions
Clip-Tight
™
Socket
Clip-Tight Socket
Eaton’s series of 1MP, 1MM,
3MM metering devices
incorporate the only socket
base in the industry without
fasteners. This component
uses jaws on both sides of a
thermoplastic polyester glass
fiber reinforced (PBT) base,
eliminating the need
for self-tapping screw
connections to vertical
busbars.
One-Piece Vertical Busbar
One-Piece Vertical Busbar
Eaton’s series of 1MP, 1MM,
3MM meter stacks embody
a one-piece busbar
construction to each socket,
as well as a one-piece cross
bus to each tenant main.
Because the Eaton design
uses the Clip-Tight meter
socket and does not have
busbar joints, the chance of
hot spots occurring is virtually
eliminated.
Field Phase Balancing
Field Phase Balancing
Due to popular incoming
three-phase voltage systems
and single-phase outgoing
loads, installers have the
option to field phase balance
on the individual stack (A-B,
B-C, A-C). This feature
eliminates the chance of
installing an incorrectly
phased device due to its
versatility.
Horn and Manual Bypass
Horn and Manual Bypass
With an increasing demand for
uninterrupted power, Eaton’s
series of 1MP, 1MM and
3MM meter sockets offer
horn (ringless style) and
manual (ring style) field-
installable bypass accessories.
These accessories provide
uninterrupted tenant service
if a meter is pulled for
inspection or replacement.
Lever Bypass
Lever Bypass
Due to commercial
requirements, Eaton offers
a lever bypass (as standard)
on all 35MM and 37MM
devices. Each socket base
consists of a lever bypass,
which also releases the jaws
(when lever is engaged in
bypass position), enabling
utility company mechanics to
easily remove and/or insert
utility meter.
Test Bypass Disconnects
Test Bypass Disconnects
Eaton also provides
commercial meter stacks
with EUSERC required test-
bypass disconnects (35SS
and 37SS). This bypass is
used in the same applications
as the lever bypass and it is
required by EUSERC utilities.
Main Tenant Breaker Cover
Main Tenant Breaker Cover
Each tenant circuit breaker
is protected by a lockable
raintight cover that secures
the breaker against
unauthorized operation. The
tenant breaker cover is a high
impact plastic to resist wear,
rusting and corrosion.
Mounting Features
Mounting Features
A standard mounting rail and
factory-installed swing away
feet speed up and simplify
installation.
