Single motor applications
Single motor applications employing a manual
motor protector (MMP) result in a simple,
compact and economical alternative to
conventional magnetic motor controllers for
manual operation of a single motor. Upstream
short circuit and overcurrent protection in the
form of fuses or a circuit breaker is required
but the MMP can replace the overload relay,
contactor and associated electrical components
and wiring for controlling the contactor.
Group motor applications
Group motor installations offer several
advantages when controlling two or more
motors or other loads over conventional single
motor starters. Several MMPs can be grouped
together and fed from a single set of fuses or a
circuit breaker. These devices can be installed
together on a single DIN rail and fed power
through three phase insulated busbars and
a power feed terminal. Protecting this group
of MMPs is a single circuit breaker or fusible
switch, sized speci cally for the load. Excellent
coordination and short circuit protection can be
achieved, as high as 50kAIC, when using the
MS325 product in this manner. Close coupling
adapters are offered to connect contactors
to the load side of each MMP for automatic
operation of each motor. If a single motor
experiences an overload, the associated MMP
trips and allows the other motors to continue
running. Numerous accessories are available
for signaling in the event of a trip, to indicate
status, to provide shunt trip and for undervoltage
release. The main bene ts of group installation
are quick, fool proof assembly, minimal wiring
and a reduction of the necessary enclosure size.
The only constraint is that the upstream circuit
protective device must be sized speci cally
for the load – a highly desirable feature in
order to provide the closest coordination
and the greatest level of circuit protection.
Article 430.53(C) of the
NEC
®
speci es the
requirements for group motor installations; all
ABB MMPs meet these requirements.
