Schneider Electric Micrologic E control unit

The Micrologic E control unit features the same protection functions and ‘ammeter’ current measurement capabilities as the Micrologic A control unit, but the new unit 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.

The unit is suitable for applications in office buildings, hospitals, data centres or any commercial or industrial facilities. It can be installed in new or existing circuit breakers. Energy data is viewable by facility managers or maintenance personnel through the integrated LCD, an optional front-panel display module or over a communications network using Schneider Electric or third-party software.

The models feature internal architecture that safely and reliably separates protection and measurement functions. Its LCD ‘auto-scroll’ function that enables personnel to safely view all the most important measurements without having to touch the circuit breaker. A new trip history supports fast troubleshooting by storing in onboard memory the trip type, date and timestamp for the last 10 trip events, while two programmable relay outputs can be controlled by trip events.

Also introduced is a BCM ULP communications module option for Compact and Masterpact circuit breakers that enables connection of an FDM121 display for local viewing of energy or other measurements on the door of an electrical cabinet. The BCM ULP module also provides a Modbus port for plug-and-play network connectivity with centralised energy management or automation software. This enables data from every Micrologic E control unit across a facility to be easily gathered, analysed and reported on to reveal opportunities, drive energy-efficient behaviour and to validate savings from equipment upgrades or process changes.
