Product Description
PR 240 electronic motor protection relay is an excellent choice for telemetry applications to monitor, meter and control Motor. Its small size, low cost and remote HMI options make the relay a perfect option for power distribution systems to be used in end-of-line monitoring and power metering.
PR240 motor temperature protection relay offers low-voltage motor protection in almost all applications, including pumping, air-based, chiller, and bulk-material applications. The motor thermal relay can be configured as full range of medium-voltage, three-phase induction and synchronous motors protect relay.
