Eaton Expands Circuit Breaker Power Monitoring and Metering Capabilities, Improving Equipment Reliability, Efficiency



Pittsburgh ... Diversified industrial manufacturer Eaton Corporation is expanding its circuit protection product offering with the PM3 power monitoring and metering module, which monitors the power of branch and main circuit applications. The PM3 is a device that measures current and voltage, calculates power and energy usage, and provides breaker status. It is designed for Eaton Series G L-Frame and Series C K-Frame molded-case circuit breakers. Engineered for original equipment manufacturers (OEMs), the PM3 module is applied where monitoring is important.

"The PM3 module is designed to improve electrical system reliability and efficiency, by helping to reduce utility costs and increase equipment performance," said Shawn Diamond, product manager at Eaton. "It enables real-time monitoring, metering and communication of phase current and voltage, with real and reactive calculated power and energy - making it easier for customers to detect potential power concerns."

An Underwriters Laboratories (UL) listed, add-on communications device, the PM3 module can be mounted to the load side of three-pole Series G LG and Series C KD breaker frames and monitors electrical system parameters. Regardless of whether the trip unit is thermal-magnetic or electronic, the PM3 can be adapted to applications where monitoring is critical. It can also be installed in reverse-feed applications with reverse-fed breakers. Measurement accuracy is within two percent of the reading.

The PM3 power monitoring and metering module communicates through INCOMTM protocol, and is compatible with Eaton Power Xpert Gateway (PXG) for web page and Ethernet capability. Versatile, it communicates to the web or Modbus TCP/IPthrough any of the Eaton PXG gateways.

Available in two versions, the 480 volt (V) PM3 module operates in 208V to 480V applications, and includes an integral power supply. The 600V model operates 208V to 600Vapplications and requires 24V direct current auxiliary power.
