Manual Motor Protectors (MMPs) features a
pushbutton or rotary ON/OFF manual
disconnect, Class 10 adjustable bimetallic
overload relay and fixed magnetic short
circuit trip capability in one compact unit.
The Frame B size (45 mm) for motors has
FLA ratings up to 32A. The XTPB and XTPR
MMPs are UL Listed under UL 508 as
Manual Motor Protectors. They provide an
economical solution for applications
requiring simple manual starting and
stopping of motors. When used as an MMP,
they are typically installed in an enclosure.
Many enclosures are offered as accessories
for the MMPs. Separate short-circuit
protective devices, such as circuit breakers
or fuses, are wired ahead of the MMPs. The
short-circuit protective device should be
sized per the NEC code and should not
exceed 400% of the maximum FLA dial
setting of the MMP. A Group Motor
Installation can be defined as more than one
motor circuit protected by a single set of
fuses or circuit breaker on a motor branch
circuit. This eliminates the need for
individual fuses or circuit breakers for each
motor circuit. Substantial component cost
savings, panel space savings and reduced
wiring installation time can be achieved in
Group Motor Installations. The MMPs are
tested and listed for group installation. If
remote operation is required, a magnetic
contactor can be wired in series with the
MMP. Manual Motor Protectors are selected
based on the overload current range
required for a given motor. This current
range is determined from the motor Full
Load Ampere rating and Motor Service
Factor usually found on the motor
nameplate. For motors with service factors
less than 1.15, multiply the motor FLA by
0.90 to select appropriate MMP. Example:
For motor having FLA of 6.4 A and service
factor of 1.0 (6.4 A x 0.90 = 5.76 A), select
Model Number: XTPB6P3BC1
