Energy Metering Guide for 600 A (and Below) Low Voltage
(600 V and Under) Applications
Introduction
Rising energy costs and increased environmental awareness have spurred
investors, developers, builders, operators and occupants to make their
buildings more energy efficient. But to truly optimize building energy
consumption, you need detailed and accurate data about how your energy
is being used. You can't manage what you can't measure.
Schneider Electric is dedicated to continually improving our solutions for
energy metering, monitoring, and management. This document provides
selection guidance when applying low voltage metering options in 600 A
(and below) applications.
Functionality Comparison
Each metering option available from Schneider Electric has its advantages.
With the introduction of metering circuit breakers in the 600 A and below,
600 V and under range, there are specific advantages whether you choose
the circuit breaker offer or a power meter offer.

In addition to feature advantages, there are also application fit differences
when choosing integrated metering within PowerPact circuit breakers and
PowerLogic power meters. PowerPact circuit breakers with Micrologic trip
units are better suited for new construction projects unless the following
requirements are in place:
•
•
•
Sub billing (utility grade)
Advanced power and energy quality
Onboard logging
PowerLogic power meters are better suited for retrofit projects.
