Product Description

The PM3 is the perfect solution for main, branch circuit and standalone monitoring/metering applications. With information at your fingertips, you can meter, monitor and communicate phase current and voltage with calculated power and energy.

The PM3 is versatile, as it connects to the load side of a molded-case circuit breaker (MCCB) and communicates easily to a local network or the Internet through Eaton Power Xpert® Gateways (PXGs). Cost of ownership is reduced through ease of installation. The PM3 is your ideal MCCB metering solution.

Application Description

• Communications via Modbus® and Eaton’s INCOM™ protocol; compatible with Eaton’s PXG for Web page and Ethernet capabilities
• Works in 240 Vac PM3, 480 Vac and 600 Vac applications
• 480 Vac PM3 has internal power supply to power electronics
• 600 Vac PM3 requires 24 Vdc auxiliary power
• Seamlessly integrates with thermal-magnetic or electronic trip units
