BSPD SPDs for overvoltage protection on
switchgear and power distribution panels
Factory sealed to improve electrical safety
All BSPD Series units are factory-sealed to eliminate arc flash
and shock hazards, as the user/installer has no chance of coming
into contact with energized parts. The units also contain no user-
serviceable parts or wire lugs that require periodic retightening to
eliminate the need for periodic maintenance.
Introduction
The BSPD Series of surge protective devices are tested by
Underwriters Laboratory and Listed to UL 1449, 4th Edition to help
ensure equipment is protected with highly reliable surge protection
technology. Delta and Wye system units are available in three
configurations to increase application flexibility. The BSPD Series
is for installation external to an electrical enclosure or panelboard.
Application of BSPD Series units throughout a facility will help
ensure that equipment is protected.
Bussmann SurgePOD technology eliminates the need for
additional fusing
BSPD uses Bussmann SurgePOD modules that each contain
an internal element that safely disconnects upon reaching an
overvoltage breakdown condition.
Applications
BSPD Series units are available for common Delta and Wye system
voltages in a variety of surge current capacity ratings from 120kA
to 400kA. Available in three configurations, the BSPD Series’
features and options make it easy to specify units for many electrical
applications including service entrances, distribution switchboards,
panelboards and point-of-use. All possible combinations of product
attributes are available for ordering in the catalog number system
(see page 7).
Prewired
All BSPD units are factory wired for ease of installation. Simply
install any necessary conduit runs, mount the unit and make all
wire connections. No need for internal wiring or access to the unit’s
inside.
Compact size takes less space
Available in enclosures that are up to 50% smaller than other
products with comparable ratings the BSPD Series come in NEMA 1
and 4X enclosures that differ in size according to their surge current
capacity (I
max
).

Features
•
BSPD uses Bussmann series SurgePOD™ thermally protected
Metal Oxide Varistor (MOV) technology to safely shunt
overvoltages to ground while its thermal disconnect capability
eliminates the need for additional fusing
200kA SCCR meets the highest NEC
®
requirements
Models available to meet the overvoltage protection needs of
Wye and Delta electrical systems from 208 to 600 volts, 3-phase
BSPD has the highest nominal discharge current (I
n
) of 20kA
per UL 1449 4
th
Edition. This rating indicates the SPD’s ability to
handle a number of large-magnitude surges over a short period of
time and remain operational.
120kA to 400kA surge current capacity (I
max
) ratings meet
the needs of larger switchgear and power distribution panel
applications
Optional Form C contact relay, EMI/RFI filtering and surge counter
available to meet additional system requirements.

The 120-200kA surge current capacity units are housed in a 74
square-inch enclosure that is only 3-1/2 inches deep.
The 300-400kA surge current capacity units are housed in a 74
square-inch enclosure that is only 6 inches deep.
The 120-200kA surge current capacity units are housed in a 108
square-inch enclosure that is only 5-3/8 inches deep.
The 300-400kA surge current capacity units are housed in a 108
square-inch enclosure that is only 7-11/16 inches deep.

BSPD SPDs for overvoltage protection on
switchgear and power distribution panels
Enhanced protection status indicators
Unlike many SPDs that only have single-color indicators, all BSPD
units include green and red Light Emitting Diodes (LEDs) that
indicate the true protection status for each phase.
If power is removed from any one phase, the unit’s LEDs continue
to indicate the protection status on that phase — regardless if power
is applied to the phase. This feature ensures proper indication.
Although many SPDs on the market have N-G surge protection,
they do not always have a means of monitoring and indicating the
protection status of that mode. All BSPD units for Wye systems also
contain green and red LED surge protection status indicators for the
Neutral-to-Ground (N-G) connection. Like the phase protection status
LEDs, the N-G protection status LEDs show the true protection
status in the N-G mode.
By specifying the BSPD Series, users are supplied with accurate
information concerning the surge protection status of their electrical
systems.
