General
Standard reactive compensation capacitors are
available from Aerovox in the following product
categories:
AMP0 – Vacuum-impregnated metallized
polypropylene, compact size.
MMP0 – Vacuum-impregnated metallized
polypropylene, rugged welded case.
Available standard ratings at 60 Hertz for each
respective category are shown in Table 1. Please
consult the factory for other voltages and KVAR
ratings.

Harmonic Distortion
Harmonic distortion is the resulting non-sinusoidal
current waveform generated by a non-linear load. The
most common non-linear load is a pulse rectifier, which
is used in most switch mode power supplies, variable
speed drives and uninterruptible power supplies. The
distorted current waveform generates a distorted
source voltage due to the system (electrical power
system) impedance. A distorted waveform can be
analyzed by decomposing it into a fundamental
component (line frequency) and higher frequency
components of varying amplitude.
The effects of harmonic distortion on metallized film
capacitors are (1) higher operating temperature
2
because of higher I R losses, and (2) higher voltage
stress on the dielectric. Both of these factors will
shorten the life of a capacitor dramatically.
All Aerovox Power Factor Correction capacitors are
designed to handle harmonic currents, however,
Aerovox also offers capacitors that are custom
designed for systems with high harmonic distortion. By
using our high-harmonic capacitors in your harmonic-
rich application, you will have a more robust

Construction
All Aerovox Power Factor Capacitors are impregnated
with a dielectric fluid to give added insulation, excellent
corona protection and a moisture barrier. The dielectric
fluid is considered a green (benign), environmentally
friendly material. All capacitors are 100% leak tested.

Cover Terminals
All low voltage cells are available either in three or five
terminal configurations, specified by KVAR rating (see
individual specifications). The medium voltage cells are
not available with 5 terminals. The internal schematics
for these terminal configurations are shown in Figure 1
and Figure 2. The standard five terminal designs can
be connected with external components, as shown in
Figure 3, to obtain a loss-of-kVAr feature. In this
configuration, a neon indicator lamp will illuminate
during a loss-of-fuse or a loss-of-capacitance
condition.

Warranty Information
Aerovox warrants the product for 18 months from the
time of shipment or 12 months from the time the unit(s)
are put in service, whichever comes first.
Safety Features
Discharge resistors
are placed internally on MMP0 and
externally on AMP0 capacitor cells. The resistors are a
safety feature that drains the voltage on the terminals
once the unit is taken offline to less than 50 volts in
one minute or less for cells rated up to 600 VAC or in 5
minutes or less for cells rated over 600 VAC. The
resistors are sized for long life continuous operation at
maximum-rated temperature.
Aerovox low-voltage capacitor cells have UL and C-UL
recognized
pressure-sensitive circuit interrupters.
The
circuit interrupters purpose is to safely remove the
capacitor from service at end-of-life or under heavy
fault conditions and still maintain case integrity.
Aerovox low-voltage capacitor cells are listed for use
with or without fuses at 10,000 amps available fault
current (AFC rating).
Self-healing technology:
in case of an overload, the
self-healing properties of the low-loss metallized
polypropylene will prevent permanent dielectric
breakdown.

Three-Terminal Capacitors

Five-Terminal Capacitors
Mounting Orientation
All Aerovox power factor correction capacitor cells can
be mounted in a vertical position with the terminals
facing up or horizontally. The units should not be
mounted upside down. For proper operation of the
pressure interrupter, capacitors mounted in banks
must have enough space between them to allow for
heat ventilation and swelling. For minimum distance
between units, see the table 3. In cases where
brackets or mounting straps are used, there should
only be enough pressure on the unit to hold it in place.
See Table 3 for proper top and side clearances.
