BSPD SPDs for switchgear and power distribution panels
1.0 Introduction
1.1 Manual organization
This installation manual describes the safe installation, testing and
operation of the Bussmann
™
series BSPD Surge Protective Devices
(SPDs).
This manual is organized into the following sections:
1.0 Introduction
2.0 Installation
3.0 Operating features
4.0 Troubleshooting
5.0 Specifications
6.0 Catalog number system
7.0 Warranty
1.2 Product overview
The BSPD protects critical electrical and electronic equipment from
damage by surges. This is done by shunting surges (and other
transient disturbances) to ground and away from the equipment on
the circuit that’s being protected. It does this in nanoseconds by
providing a low impedance surge path-to-ground while allowing a
continued, uninterrupted flow of power to the circuit’s loads.
The BSPD is designed for wall mounting (or other vertical surface)
as close as possible to the electrical cabinet or panelboard. The
BSPD is available in voltage ratings from 208-600Vac, with surge
current capacity ratings of 120kA, 200kA, 300kA and 400kA in either
NEMA 1 or NEMA 4 enclosures.
The BSPD is available in three configurations; 1)Basic, 2)Standard,
and 3) Standard with Surge Counter as described in Section 3,
Operating Features
. Each configuration is available for Delta and Wye
electrical systems.
All BSPD models have been tested by Underwriters Laboratory (UL)
and are listed to UL 1449, 3
rd
Edition.
The
Basic
configuration BSPD units are Type 1 SPDs that can be
installed on either the lineside or loadside of the service entrance
panel overcurrent protective device. The
Standard
and
Standard with
Surge Counter
configurations are Type 2 SPDs that can
only
be
installed on the loadside of the service entrance panel overcurrent
protective device.
All BSPD units enable compliance with 2014 NEC
®
700.8 that
requires a listed SPD to be installed in or on all emergency system
switchboards and panelboards.
1.3 Safety precautions
A licensed/qualified electrician must complete all instructions in
this manual in accordance with the National Electric Code (NEC
®
),
state, and local codes and agency requirements, or other applicable
country codes. All applicable local electrical codes supersede these
instructions.
1.4 Catalog numbering system
Each BSPD has a name plate that identifies the parameters used
for manufacture. These parameters are expressed in letters and
numbers to reflect the series, kA rating, voltage/system type code
(e.g., Wye or Delta), configuration and NEMA enclosure rating, as
shown in Table 1. To see the complete catalog numbering / product
build-a-code system, see Section 6.0,
Catalog Number System
.
Table 1. catalog numbering system
For example, a 208 volt Wye (4-wire plus Ground) for use in a
NEMA 1 application requires an SPD build-a-code catalog number
BSPD200208Y3K, where:
BSPD
= SPD model
200
= the kA rating (200kA)
208Y
= the voltage/system type (208Vac, Wye)
3
= the configuration (Standard with surge counter)
K
= the enclosure rating (NEMA 1)
These numbers appear as part of the product labels attached to the
side of the SPD. See Figure 1.
