Sentron® SMP Switchboards

Construction Details

Simplified system design.

A typical SMP switchboard consist of
a floor mounted, wall supported ser­vice section, and a distribution section.
The wireway can also be added where
required by the local utility or if addition­al cable termination space is required.

Wireways are modular to allow
flexibility.

The wireway is available in 2 depths to
suit customer needs. Wireway has split
front doors as standard with optional
hinged doors. The lug pads are standard
NEMA hole pattern and accept up to 5
mechanical lugs or 6 compression lugs.

90oC rated wireway.

The termination temperature for main
incoming cables can be sized at 90oC
for bussed pull sections.

Service Entrance Sections house a
variety of equipment.

b

Service Entrance Sections.

Service sections can be fed directly from
overhead by cable.

Service entrance sections equipped
for bottom feed will accept cable from
underground directly into the service
section.

b

Utility Metering
In addition to the main device, the
service section contains utility metering
provisions. “Cold” metering provisions
(CT’s on the load side of the main
device) are furnished. The CT’s are
provided by the utility company. The
compartment will be built to utility
company standards, with hinged doors
and provisions for utility metering
equipment.

Distribution Sections have ample
wiring room and front accessibility.

Generous top or bottom gutters have
been created by locating the bus-link in
the top or bottom of the distribution
section, so there’s ample room to run
cables into the distribution section and
make connections.

Standard bolted covers allow complete
access to load conductors. Future
flexibility comes standard in the
Siemens SMP switchboard. The
distribution section can accommodate
any combination of panel mounted
devices, including MCCBs and fusible
disconnect switches.

Operating temperatures are in
accordance with CSA Standards

Bus bars are available in standard
tin-finished aluminum or optional
silver-finished copper. Standard bus is
sized on the basis of heat rise criteria,
in accordance with CSA C22.2 #31. All
bus bars are sized to limit heat rise to
65°C above an ambient temperature of
40°C.

Construction

Bus-Link Connections are accessible
from the front.

The Bus-Link can be bolted from the
front of the switchboard. Each bus-link
is attached by grade five bolts to assure
solid joints between sections, and to
maintain full bus ampacity through the
joint.

To make installation and servicing of the
bus-link easier, all phase and neutral
busses are stacked one above the other.

Cable Terminals

Screw mechanical connectors (lugs) are
provided as standard equipment.

b

User Metering
The service section provides space for
the Siemens Digital Meter with remote
display, and it’s associated components.

b

Main protective device
The MCCB is mounted individually
so that it can be located quickly in an
emergency. SMP switchboards will
accommodate different types of main
circuit breakers. Selection depends on
the characteristics of your individual
electrical system.

SMP Switchboard Introduction

Whether the design is for a 240V AC, 400 ampere
system; a 600V AC, 1200 A ampere system; or
something in between, Siemens Sentron Switchboards
should be considered. Every aspect of design has
been aimed at improving layout convenience, reducing
installation costs, and minimizing the impact and
cost of system changes. These switchboards provide
the space saving construction and service flexibility
necessary in systems for light industrial plants, retail
strip malls, and commercial buildings.

Service entrance sections of the SMP accepts a wide
range of Sentron Molded Case Circuit Breakers as
main disconnect devices.

The SMP switchboard is designed for special
configurations. It can be equipped with incoming and
outgoing cable/conduit connections, supplied with
metering and other special features.

The distribution sections of all Sentron Switchboards
are designed with improved wiring space and
greater accessibility. They’re also designed for easier
installation and maintenance. Conveniently located
bus-link without compromising useful wiring gutter
space, and standard bolted gutter covers offer
complete access to load conductors. Front accessibility
to bus and protective devices makes adding or
replacing circuit breakers or switches quick and easy.

Protective Devices - Molded Case Circuit Breakers

Standard

Breakers are designed for commercial, industrial, institutional and other
heavy duty applications. They are rated up to 600V AC and 250V DC. Their
interrupting ratings are higher than normal duty breakers.

High Interrupting
Breakers are designed for heavy duty applications where the interrupting
requirements exceed the ratings of heavy duty breakers. They are rated up to
600V AC.

Current Limiting
Molded case breakers incorporate the exclusive I-T-E blow-apart interruption
principle. They meet the CSA requirements for current-limiting breakers.
Current-limiting circuit breakers can limit the let-through I
the I2t of one-half cycle wave of the symmetrical prospective current without
any fusible elements when operating within their current-limiting range.
