Descriptive Information
RBC Capacitors for Motor Run Applications
Metallized film capacitors are unsurpassed in terms of size, weight, performance, and reliability for AC
applications. RBC - Capcom brings over 60 years of capacitor manufacturing experience to the product
lines described in this publication. These capacitors represent the best in product design for long-term
reliability and safe operation. RBC’s materials, product, and process development work continue to
provide capacitor users with outstanding total value.
The Gem III Motor Run Capacitors are widely used with permanent split phase capacitor motors for the
more efficient use of electricity. These motors are used in heating and cooling equipment, appliances,
business machines, office equipment, and a wide variety of light industrial equipment.

Descriptive Information
GEM III Construction
RBC‘s
Gem III capacitors are manufactured with high
-
grade
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 high-speed, 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 connection to the
extremely thin edges of the metalized electrodes. This
process is critical to the quality and performance of the
capacitors.
The rolls are assembled in metal cases, RBC’s 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 terminal-to-terminal and
terminal-to-case.

*Underwriter's Laboratories
Pressure Sensitive Inter
rupter
All the capacitors listed in this publication contain
RBC's Pressure Sensitive Interrupter (PSI). This
device, developed by RBC, is designed to sense the
build-up of pressure within the capacitor if a fault
occurs and to interrupt the internal electrical
connections before the case can rupture.
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.
In the Catalog Number listings a four character U.L.
Code, Pxxx, is given. This number is part of the listing
for RBC 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
these capacitors.
Mounting Considerations
Vertical Clearance
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.
Cut
-
Out Clearance
In certain instances capacitors are mounted
with the top of the capacitor 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.

for a sinusoidal waveform.
Leakage Current: 30 µA maximum
Frequency: 50/60 Hz For higher frequencies use the General Purpose
AC Capacitor Series.
Operating Temperature: -40 ˚C to +70 ˚C
Storage Temperature: -40 ˚C to +90 ˚C
Operating Life: 60,000 hours with 94% survival
Dissipation Factor: 0.1% maximum
Case Material/Finish: Unpainted Aluminum case, tern plate steel cover.
Contact RBC if material/finish to meet UL outdoor
standards is required.
Terminations:
‘Combo’ terminal: 0.250” x 0.031” quick connect blades.
Dielectric Fluid: Dielektrol VI
Internal Protection: UL recognized Pressure Sensitive Interrupter. See
Ratings Table for RBC’s UL code Number listed under
RBC’s UL File E7793 (N). For UL submittals with these
capacitors use the RBC ’Pxxx’ number not the Catalog
Number. The corresponding generic UL designation that
includes the Available Faults Current (AFC) rating is given
below. All these capacitors are capable of interrupting
available fault currents of up to 10,000 amperes.

370 and 440 Volts AC
This capacitor series is designed specifically for the motor run
applications where the capacitors are used in conjunction with
permanent split capacitor type motors. They may be used on either
50 or 60-Hertz systems but should not be used at higher
frequencies or in applications where higher frequency harmonics
are present. For those types of applications the General Purpose
AC Capacitors shown on the following pages should be used. If
there is any question regarding the correct application of these
products, please contact your RBC sales representative.
