Schneider Electric South Africa has announced the release of the Micrologic E control unit as an option for the company’s Masterpact and Compact NS ranges of circuit breakers.
While featuring the same protection functions and ‘ammeter’ current measurement capabilities as the best-selling Micrologic A control unit, the new Micrologic E adds energy measurement for a low incremental cost. This capability enables energy metering at key points throughout an electrical distribution system, supporting efforts to reduce energy consumption, energy-related costs and greenhouse gas emissions.
Ideally suited to applications in office buildings, hospitals, data centres, or any commercial or industrial facilities, the Micrologic E can be installed in new or existing circuit breakers. Energy data is viewable by facility managers or maintenance personnel through the integrated LCD display, an optional front-panel display module, or over a communications network using Schneider Electric or third-party software.
“Energy metering is a key first step toward energy efficiency and we believe intelligent, energy measurement capable breakers will soon become the industry standard,” says Nelen Govender, low voltage power manager at Schneider Electric South Africa. “We were the first company to introduce affordable energy measurement in a circuit breaker with the Compact NSX range. The Micrologic E control unit extends this same capability across the Compact NS and Masterpact ranges, giving customers a smart, cost-effective alternative to installing a separate power meter. This puts energy metering in more places where it is needed, helping customers isolate where and when the most energy is being consumed or wasted.”
The Micrologic E is the newest addition to the established Micrologic series of circuit breaker control units, bridging the gap in functionality between two lower and two higher models, and offering energy (at 2% accuracy), current, voltage and active power measurements. All Micrologic models feature an internal architecture that reliably separates protection and measurement functions.
The unit also introduces a unique LCD ‘auto-scroll’ function that enables personnel to view all the most important measurements without having to touch the circuit breaker. A new trip history supports fast troubleshooting by storing in on-board memory the trip type, date and timestamp for the last 10 trip events, two programmable relay outputs can be controlled by trip events.
