The Schneider Electric METSEEM3570X is a PowerLogic EM3570 series electronic multi-function panel meter, built for sub-billing, multi-tariff, and partial metering applications. It clips onto a DIN rail inside a stationary indoor panel and accepts low-voltage current transformer inputs at 0.333 V or 1 V, measuring current from 1 A up to 32767 A through external CTs. The Class 0.5 accuracy on active energy (per IEC 61557-12 and ANSI C12.20) means it delivers billing-grade readings — good enough for tenant sub-metering or energy allocation where you need better than a panel indicator but aren't paying for a revenue-certified meter.
The supply input handles 90...347 V phase-to-neutral or 156...600 V phase-to-phase, so it can run directly off a 120/208 V or 277/480 V panel without a step-down transformer. Network frequency is 50/60 Hz ± 10 % — covers both legacy 60 Hz plants and 50 Hz sites. The 32 GB internal memory logs energy consumption, demand intervals (sliding, fixed, or rolling block), and time-stamped data logs; that's enough storage for months of interval data at typical recording rates. A single relay output is available for alarm or pulse output. The backlit LCD display shows 5 digits at 126 x 94 pixels resolution, readable in a dim MCC room.
Mounting and installation
Clip-on DIN-rail mount per the standard 35 mm rail. Dimensions are 3.5 in wide by 3.6 in tall by 2.8 in deep (90 x 91.4 x 70.6 mm) — it takes up about three standard single-pole breaker spaces. Terminal torque specs: voltage and input circuits at 4.4 lbf·in (0.5 N·m), current and supply circuits at 7.08 lbf·in (0.8 N·m). Pollution degree 2 — suitable for a clean, dry control room or switchgear lineup, but not for wet or conductive-dust environments. Operating altitude up to 3000 m, so it's fine for most plants outside high-mountain sites.
