1. Application of the Cooper Bussmann BSP UL Series
The modular Cooper Bussmann BSP UL Series of Surge Protective Devices
(SPDs) sets new standards of safety and user-friendliness. They are intended
for protecting against overvoltage surges generated by remote lightening
strikes or localized switching surges in up to 600V class applications.
Typical installation locations include the main service entrance, distribution
panels, sub-distribution panels, branch circuit panels or directly associated
with a panel for specific electrical equipment such as PLC, drives or other
sensitive equipment.
Integrated mechanical coding between the modules and base ensures
against installing an incorrect replacement module. Modules can be easily
replaced without tools by simply depressing the release buttons. The
protection modules are firmly fixed to the base part of the device. Neither
vibration nor the electromagnetic forces of discharge can loosen the
protection modules.
The dual Thermo Dynamic Control monitoring in each module is based on
the intensity of the discharge current and the surface temperature of the
heavy-duty varistor. The visual indicators show the state of each module at a
glance. Green if the module is good and Red if the module has reached the
end of its operating life and needs replacement. Remote signaling of module
status is possible with an optional three-pole terminal (not field configurable;
must be ordered with SPD). A floating changeover contact can be used as a
make or break contact according to the monitoring circuit design.

2. Safety Instructions
The Cooper Bussmann BSP UL Series is to be installed only by qualified
personnel in compliance with all local and National Electrical Code
requirements. Consideration must be made for proper system protection
coordination with other SPDs. Contact our Application Engineers for
additional information or assistance.
Always de-energize the system and follow prescribed safety procedures
while installing and connecting the SPD. SPD ratings must be compliant with
the application and must not be installed in a more severe environment that
subjects the SPD to higher voltages, currents or energy levels than allowed
for in its technical specifications. The SPD is designed for indoor
applications. If installed in a harsh environment, the SPD must be placed in a
suitably rated NEMA enclosure. Opening or tampering with the protection
modules may damage the effective operation of the SPD and will void the
warranty.
3. General Installation Instructions
Consult Articles 250 and 285 of the NEC®and IEEE Green Book, Standard
142. Also consider the requirements of the Canadian Electrical Code,
if applicable.
UL Installations: The Cooper Bussmann BSP UL low voltage blue series is
designed to be installed without additional fuses per UL 1449 3rd Edition. It is
suitable for use on a circuit with maximum SCCR and Nominal Voltage
according to Technical Data. This device features an internal protection sys-
tem that will disconnect the surge protective module at the end of its useful
life, but will maintain power-to-load, now unprotected from an overvoltage
condition. If this situation is undesirable for the application, the plug-in mod-
ule must be replaced.
System Voltage: Make sure that the SPD is correctly rated for the applica-
tion. The maximum continuous operating voltage (MCOV) must not be
exceeded.
Mounting: The SPD should be installed as close as possible to the device it
is protecting. Good installation practice is to keep conductor length as short
and straight as possible. The SPDs mount on a 35mm DIN-rail that should
be securely mounted to the back of the panel’s interior using ¼ inch bolts
every 8 inches (200mm). The SPDs can be mounted onto the DIN rail by
sliding in from either open end, or directly on by compressing the spring-
loaded clamping device. The SPD’s location shall permit sufficient clearance
for conductor power and signaling connections.
Conductor Connections: Phase connections to the SPD and Ground side
connections from the SPD to the ground bus must use the wire size
indicated in the technical specifications. Insulation should be stripped back
½ inch as shown. All conductor terminal screws shall be tightened to
45 Lb-In (5 N•m). If the SPDs are installed with conductor lengths from the
main bonding jumper (usually service entrance) longer than six feet (two
meters), then an additional SPD must be installed between neutral and
ground.
Grounding: For proper operation, the SPD must be connected to a low
impedance ground. Good installation practice is to make sure the SPD
grounding conductors are as short and straight as possible using the
specified wire size. Use a local equipotential bonding bar if possible. Contact
our Application Engineers for additional information or assistance.
Remote Contact Signaling: If using the optional remote contact signaling,
torque terminals to 1.7 Lb-In (0.2 N•m). Contacts are rated at 250Vac/0.5A
or 250Vdc/0.1A, 125Vdc/0.2A, 75Vdc/0.5A.
Problem Diagnostics: If there should be any problem please contact your
local Cooper Bussmann representative.
NOTES ON FUSING
• No additional fusing is needed for UL installations that DO NOT
require an SCCR rating.
• If an SCCR rating is needed on a UL installation, do not use this
low-voltage blue label UL-SPD. Use an appropriate unit from the
high SCCR black label UL-SPD product range. For details on
available high SCCR units, visit www.cooperbussmann.com/Surge.
• If uncertain about the correct unit to install for your application,
contact Cooper Bussmann Application Engineering Team M-F, 8:00
a.m.-5:00 p.m. central time at 636-527-1270, e-mail
fusetech@cooperindustries.com, or fax 636-527-1607.
