Capacitors for General Purpose Applications
Metallized film capacitors are unsurpassed in terms of size, weight, performance, and reliability
for AC applications. RegalBeloit brings over 60 year of capacitor manufacturing experience to
the product lines described in this publication. These capacitors represent the best in product
design for longterm reliability and safe operation. RegalBeloits materials, product, and
process development work continue to provide capacitor users with outstanding total value.
The specific products in this bulletin are aimed at market / application segments for General
Purpose, Power Supply, and Electronic Power Conversion.
The GEM III General Purpose Capacitors are used for filtering on a wide variety of light
industrial equipment. The conversion of electrical power and uninterruptible power supplies and
drive control systems requires filter capacitors. An application note is included to help
customers in the correct choice and use of these capacitors.

Descriptive Information
GEM III Construction
RegalBeloits GEM III capacitors are manufactured with
highgrade metallized polypropylene film. This film is in
the range of 5 to 10 microns thick, depending on the
application, voltage, and conditions. The metallized
electrode is several hundred angstroms thick.
The film is wound into capacitor rolls on highspeed, high
precision machines. The winding is extremely tight so that
there is not enough space between the layers for corona
(localized partial electrical discharges) to occur. The rolls
are sprayed on both ends with metal to make the
connection to the extremely thin edges of the metallized
electrodes. This process is critical to the quality and
performance of the capacitors.
The rolls are assembled in metal cases, RegalBeloits
proprietary Dielektrol VI liquid is introduced under
vacuum, and the capacitors are sealed. They are then
subjected to 100% electrical testing for capacitance,
dissipation factor, and high potential electrical withstand,
both terminaltoterminal and terminaltocase.

Product Safety
The PSI carries U.L.* recognition for applications where the specified fault currents are not
exceeded. The fault current is the maximum current that is available from the circuit to flow
through the capacitor if the capacitor were to become a short circuit with zero impedance. It is
the responsibility of the capacitor user to determine what the available fault current is
for a particular application.
All the capacitors listed in this publication contain RegalBeloits Pressure Sensitive Interrupter
(PSI). This device, developed by GE, is designed to sense the buildup of pressure within the
capacitor if a fault occurs and to interrupt the internal electrical connections before the case can
rupture.
In the Catalog Number listings a four character U.L. Code, Pxxx, is given. This number is part
of the listing for RegalBeloit in U.L. File No. E7793. When applying to U.L. for approvals or
recognition of equipment using these capacitors refer to the Pxxx number and not the Catalog
Number of the capacitor in question.
Proper operation of the PSI requires that the cover be able to expand without restriction. The
following mounting considerations should be noted in mounting the these capacitors.

Product Safety
There must be sufficient clearance between
the tops of the terminals (and/or the
assembled wire connectors) and a plane
perpendicular to the capacitor terminals. This
clearance must be at least 0.5 inches plus
the electrical spacing requirements of the
end application.
In certain instances, capacitors are mounted
with the top of the capacitors case resting
against the chassis and the terminals
protruding through the chassis. Care must
be taken to see that the cutout in the
chassis is large enough. The following
dimensions are recommended.

Gen Purpose AC Capacitors GEM III
This series of GEM III is designed specifically for applications such as AC filters where harmonic
frequencies greater than 60Hz are common. Application Data is provided starting on page 9 that gives
the Equivalent Series Resistance (ESR) for these units. This allows the user to calculate the losses for
each design / application and to ensure that they are kept within the permissible limits. Any questions
regarding the suitability of a capacitor for a particular application may be referred to RegalBeloit
Engineers by contacting your RegalBeloit sales representative.
