System Overview

The Power Xpert™ C445 is an advanced, global motor
management relay with full line, load and motor system
monitoring and protection. It is designed to protect single
or three phase AC electric induction motors ranging from
0.3 to 800 A. In the event of an overload trip, C445
disconnects power flow to the monitored motor. C445
additionally provides advanced monitoring and control
algorithms for efficiency, torque, speed, energy deviation,
and voltage loss restart.
C445 offers a modular pass-through design, separating
monitoring, protection and control functionality into individual
modules. This allows the user to select the appropriate
options for each module and combine them to meet the
exact needs of their application. The C445 also offers
multiple pre-programmed operation modes to support fast,
easy and error-free installation for the majority of
applications.
