Incorporated Fixed Resistor
Power Rating, Watts
A fixed resistor can be incorporated at the end
of CW or CCW rotation to a minimum of 15ꢀ of
the total resistance value. The rotation is
shortened by an amount proportional to the ratio
of the fixed resistor to the total resistance value.

Insulated Construction (Standard)
Standard: /8”-32 NEF-2A thread, .375” (9.53mm)
The contactor is insulated from the base and
connected to the center terminal on the insulated
construction. This construction can be supplied
with the center terminal and one end terminal at
either end of the resistance element or with the
center terminal and terminals at both ends of the
resistance element.
or .250” (6.35mm) long. M9 x 0.75
available.
Special: As required in increments of 1/16” (1.58mm)
Locating Lugs
Standard Position: Left side (with terminals down)
supplied, unless otherwise
specified.
Grounded Construction (Optional)
Other Positions:
Available with right side only, both
left and right, or without lugs.
The grounded construction is supplied without a
center terminal and the contactor is connected to
the case. This construction can be furnished with
one end terminal at either end of the resistance
element or with terminals at both ends of the
element.
