Motor Wiring Connections—Typical
This section shows typical diagrams for basic overload
applications. Each C445 system consists of a base Module
C445B... and a Measurement Module C445MA...,
C445MB..., or C445MC...
Options such as the user interface C445U..., current
transformers, and potential transformers may be connected
to meet the operating requirements of the customer
application.
The C445 can be configured utilizing external current
transformers (CT's) and potential transformers (PT's).
