PITTSBURGH … Diversified industrial manufacturer Eaton is expanding its circuit protection product offering with the PM3 power monitoring and metering module <http://www.eaton.com/Eaton/ProductsServices/Electrical/ProductsandServices/CircuitProtection/MoldedCaseCircuitBreakers/PM3Communications/index.htm> , which monitors the power of branch and main circuit applications. Designed for Eaton® Series G® and Series C® molded case circuit breakers, the PM3 with Modbus® RTU measures current and voltage, calculates power and energy usage, and provides breaker status. It is designed for Eaton® Series G® and Series C® molded-case circuit breakers. The PM3 module is applied where monitoring and metering are important and is engineered for original equipment manufacturers (OEMs).
“The PM3 module is designed to improve electrical system reliability and efficiency, by helping to reduce utility costs and increase equipment performance,” said Felipe Lerebours, 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, JG and LG breaker frames, as well as Series C, FD and 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. Power and energy measurement accuracy is within one percent of the reading.
The PM3 power monitoring and metering module communicates through Modbus RTU and INCOMTMprotocols, and is compatible with Eaton’s Power Xpert® gateway for web page and Ethernet capability.
The PM3 Modbusmodule operates 208 volts (V) to 600V applications and requires 24V direct current auxiliary power. With the 310+ electronic trip units, the PM3 power monitoring and metering module also provides high load and ground fault alarming, zone selective interlocking, as well as Eaton’s Arcflash Reduction Maintenance SystemTM, which is designed to enhance personnel safety.
