ACSP2004-IG-GTF
20A Single-circuit Surge Suppressor with Ground Transient Filter
Description
Surge Suppressor / Ground Transient Filter Assembly
Model ACSP2004-IG-GTF is a compact, all-in-one device that
features Lowell’s UL Listed 20A surge suppressor Model
ACSP2004IG with a built-in ground transient filter (GTF). The
ETL listed assembly uses Lowell’s exclusive GTF filtering tech-
nology to eliminate potentially damaging electromagnetic tran-
sients / noise on the ground wire. The surge suppressor with
GTF is ideal for protecting sensitive equipment such as that
used in telecommunications, security, fire, audio/visual, broad-
cast, sound recording and reinforcement, DSP, data storage, test
& monitoring, process control, as well as business/retail PC’s
and point of sale terminals.
The surge suppressor/ground filter assembly is designed for rear
rack or wall installation. The compact 7”W x 8”H x 3”D device
features one GTF filter and two 20A isolated ground duplex out-
lets on rotating 900plates. Innovative plates (US Patent#
D535178S) allow for versatile front or side access to outlets
which can be a real benefit in crowded rack environments. Two
blank 900 plates are also provided for clean hardwire applica-
tions. Units include knockouts on all sides and LED status indi-
cators on the front.

ACSP2004-IG-GTF Surge Suppressor with Ground Transient Filter (GTF)
GTF is a RECOGNIZED COMPONENT
Electromagnetic Interference filters
(ANSI/UL 1283 - 4th Edition, 6/1998; rev 2/2004),
and (CSA C22.2 No. 8 - M1986).
Surge Suppressor
The 20A surge suppressor in assembly Model ACSP2004-IG-
GTF is UL Listed (1449-2) and endurance tested to meet
government GSA Grade A- Mode 1- Class 1requirements for
surge suppressors. It meets ANSI C62.41 and protect Line to
Neutral without ground wire contamination. It is ideal for pro-
tecting sensitive equipment from transient voltages, spikes
and surges. Far exceeding UL requirements, these suppres-
sors defeat surges up to 72,000 amps using Lowell’s Triple
Clamping RedundancyTM (TCR) technology and have a
response time of less than 5 nanoseconds. Additionally, the
surge suppressor ensures reliable performance of connected
analog or digital equipment through Transient Noise
Reduction (filtering) of 25dB@100kHz, 50dB@1MHz.
Ground Transient Filter (GTF)
Lowell’s 20A Ground Transient Filter (GTF) in assembly Model
ACSP2004-IG-GTF is a patented and ETL recognized technol-
ogy. The GTF installs in series with the ground line of electrical
circuits to attenuate high frequency transients without impeding
60Hz fault current (see Dia. 2 on page 2). It introduces less
than 0.1 ohm at 60Hz to the ground circuit thereby assuring
proper operation of any and all overcurrent protection devices
(circuit breakers, fuses, etc.).
At higher frequencies however, where the most damaging tran-
sients exist; the GTF provides significant attenuation. At 1MHz,
for example, the GTF attenuates ground noise by 25dB which
can be the difference between a sensitive system functioning
continuously or having an interruption or ‘reset/reboot’ occur-
rence. As illustrated in Dia. 2, Lowell’s ACSP2004-IG-GTF
Surge Suppressor with Ground Transient Filter (GTF) provides
a cost effective and easy-to-install 20A CleanPowerSolution for
sensitive equipment of all types.
Patented cover plate features
outlets that rotate 900for front
or side access.

GTF attenuates and filters ground transients BEFORE they reach sensitive equipment
GTF technology attenuates high frequency transients without impeding 60Hz fault current.
*Neutral is a dedicated “current carrying, grounded conductor”. It is bonded directly to the center tap of the power company transformer which is bonded to the
grounded side of the supply line.
** Ground does not carry current except during a ‘fault’ condition. Ground connections inside a building may be made through metal conduit, junction boxes, building
structural steel, water pipes, etc. They are NOT always a direct connection to the service entrance, therefore the impedance of the ground can be much higher
than the neutral. Transients CAN be induced on ground circuits and CAN find their way into sensitive equipment.
