Type F fractional motor power starters provide overload protection as well as manual
"On-Off" control for small motors in a variety of industrial and commercial installations.
Typical applications include fans, conveyors, pumps and small machine tools.
They are available in single- or 2-pole versions. Both single- and 2-pole versions are
suitable for use with single-phase a motors rated up to 1 hp. 2-pole starters may
also be used with c motors rated up to 0.75 hp.
Note: Manual starters include motor overload protection. After tripping, the overload
relay must be reset before the motor can restart.
b Basic starters.
b Starters with handle guard/lock-off.
b One starter in duplex enclosure.
b Two starters in one enclosure.
b Starters and "AUTO-OFF-HAND" selector switch.
Type K motor-starting switches provide manual "On-Off" control of single- or 3-phase
a motors, where overload protection is not required or is provided separately. These
devices are suitable for use with 3-phase a motors rated up to 20 hp. Compact
construction and a 600 V rating make these switches suitable for a wide range of
industrial and commercial uses. Typical applications include small machine tools,
pumps, fans, conveyors and many other types of electrical machinery. They may
also be used on non-motor loads such as resistance heaters.
Note: Manual switches do not include motor overload or low-voltage protection.
Should the power fail, the contacts will remain closed, and upon re-energization, the
motor will restart immediately.
b With toggle operator.
b With removable key.
Types T and M integral motor power manual starters provide convenient "On-Off"
operation of small single-phase, 3-phase or c motors. Typical applications include
small machine tools, pumps, fans and conveyors. They feature toggle or push button
operators and reliable overload protection. Pilot lights and auxiliary contacts are
available.
b Toggle (T) or push button (M) operators.
b Reliable overload protection.
b Pilot light and auxiliary contact available.
Reversing drum switches are designed to start and reverse motors by connecting
them directly across-the-line. The devices may be used with squirrel-cage motors;
single-phase a motors designed for reversing service; and series, shunt and
compound c motors. The applications should be such that across-the-line starting
of the motors is not objectionable, unless other means is provided for limiting starting
current and torque. Class 2601 drum switches are field convertible from maintained
to pulsed operation.
The reversing drum switches are suited to manual reversing control applications,
such as machine tools, woodworking machines and similar types of equipment.
Examples include lathes, milling machines, planers, grinders, shapers and boring mills.
Other possible applications include door operators, small hoists and conveyor belts.
Note: Reversing drum switches do not include motor overload or low-voltage
protection. Should the power fail, the contacts will remain closed, and upon re-
energization, the motor will restart immediately; however, if the drum switch is
assembled for pulsed operation, the handle will stay in the selected position, and the
handle position will determine the motor state.
