Control Ratings
Max HP Plugging and Jogging
Ratings shown are for applications requiring
repeated interruptions of stalled motor current
or repeated closing of high transient currents
encountered in rapid motor reversal, involving
more than five openings or closings per minute
and more than ten in a ten minute period, such
as plug stop, plug reverse or jogging duty.
Ratings apply to single speed and multi speed
controllers.
Continuous Amp Rating, Service Limit
The service limit current represents the
maximum RMS current, in amperes, which the
controller may be expected to carry for
protracted periods in normal service. At service
limit current ratings, temperature rises may
exceed those obtained by testing the controller
at its continuous current rating. The trip current
of overload relays or other motor protective
devices shall not exceed the service limit
current ratings of the controller.
be used for controlling tungsten and other
discharge type lighting loads. Class 40
contactors are specifically designed for such
loads and are applied at their full rating as
listed in the Class 40 section.
Resistance Heating Loads
Ratings apply to Class 40 contactors which
are employed to switch the load at the
utilization voltages of the resistance heating
or light producing element with a duty which
requires continuous operation of not more
than five openings per minute.
Capacitor Switching KVA Rating
When discharged, a capacitor has essen-
tially zero impedance. For repetitive switching by a contactor, sufficient impedance
should be connected in series to limit inrush
current to not more than 6 times the
contactor rated continuous current. In many
installations, the impedance of connecting
conductors may be sufficient for the
Ballast Type, Tungsten and Other Discharge purpose. When switching to connect

such that it is not necessary to derate Class 40 additional available short circuit current
contactors below their normal continuous
which should be considered when selecting
current rating. Class 40 contactors may also
impedance to limit the current.
The ratings shown for capacitor switching
assume the following maximum available
fault currents:
Size 2-3: 5,000 Amp
RMS Sym
Size 3 ½ -4: 10,000 Amp
RMS Sym
Size 5-6: 18,000 Amp
RMS Sym
If available fault current is greater than
these values, connect sufficient impedance in series as noted in the previous
paragraph.
The motor ratings in the table are NEMA
standard ratings and apply only when the
code letter of the motor is the same as or
occurs earlier in the alphabet than is
shown in the table below.
Motors having code letters occurring later
in the alphabet may require a large
controller.
