Motor Protection System
Description
The PGR-6150 Motor Protection System provides 13 protective
functions by utilizing both current and temperature inputs. It is
a modular system consisting of the control unit and an operator
interface (PGR-6150-OPI). The OPI allows programming and
displays metered values. The PGR-6150 is used to provide
current- and temperature-based protection, metering and data
logging for three-phase motors used in industrial environments.
Current transformers are not required for currents up to 25 A.
