MMP = Manual Motor Protector.

The C320LSA2 Line Side Adapter is factory assembled on the N309/359.
Reference: Technical Paper AP03402001E.
Note: Line Side Adapters are not required for non-U.S. applications. Most countries outside
of the U.S. classify the MMP as a thermal magnetic circuit breaker.

Protection in Different
Controller Types
A UL 508 Type E Self-protected Manual
Combination Starter/Motor Controller
consists of a single device having inte-
gral short circuit protection, a main set
of contacts, motor overload protec-
tion, and may also include a UL listed
Line Side Adapter (See Table 33-87).
This type of controller is a legitimate
short circuit protective device and dis-
connect means for the downstream
motor. It does require an upstream
feeder short circuit protective device,
but does not require a dedicated
branch circuit protection or a discon-
nect means if used with a Line Side
Adapter. A UL 508 Type E rating means
that the unit clears a fault and does not
experience any welding of the power
poles. A UL 508 Type E self-protected
manual motor controller will remain
fully functional should a short circuit
within its ratings occur. E.g. A307,
A308 and A309.
An IT. UL 508 Type F Self-protected
Combination Motor Controller consists
of a UL Listed Type E Self-protected
Manual Combination Starter/Motor
Controller, a UL Listed Contactor, and
a UL Listed Line Side Adapter (See
Table 33-87 ). While the Type E self-
protected manual motor controller
of this combination motor controller
device is a legitimate short circuit
protective device and disconnect
means for the down-stream motor, the
contactor is not “self-protected.” E.g. IT.
N307 – N309, N357 – N359.
In addition, as a complete assembly
or modular components, the device
should have Type 2 Coordination certi-
fication. Type 2 Coordination means
the Starter or the Controller must
exhibit little or no damage following a
major short circuit fault and should be
able to be returned to proper service
without replacing any parts. E.g. IT.
MMCs, CMCs and MMPs.
