Heaters for Contender EDS, EDS and
N1 Series Manual Motor Starters
Allen-Bradley and Cutler Hammer (Westinghouse) heaters
and starters are not interchangeable with each other.
greater than the full load current of
the motor. This applies to standard
40°C temperature rise motors. For
50°C rise motors, a heater not greater
than 115% full load current should be
selected.
However, due to the difference
between full load motor currents of
various motor manufacturers of the
same size motors, the above information is approximate.
The “Full Load Motor Current” listed in the tables below are ratings
which determine the proper heat element that should be used with the
Contender EDS/N1 Series starters listed respectively on pages O-64, O-65,
O-66 and O-68. Refer to motor nameplate for its full load motor current. It
is our recommendation that for normal
conditions the heater element selected
should have a capacity of 20 to 25%
If selection of heater element is
uncertain as might be in the case
of a motor subject to frequent starting and intermittent load, it is advisable
to contact the starter manufacturer
or his local representative giving full
particulars, such as motor horsepower,
voltage, phase cycles, name or manufacturer or pertinent data that may aid
in the selection of the proper heater
element.
