Industrial Energy Metering Solution – Schneider Electric CM4250 (CVM42) | PowerLogic Series
Where This Product Is Used
The Schneider Electric CM4250 (also known as CVM42 in certain regional catalogs) is a Square D PowerLogic series power and energy monitor engineered for demanding industrial and commercial electrical environments. Typical deployment scenarios include:
- Manufacturing Plants – Real-time monitoring of main feeders, sub-panels, and motor control centers (MCCs) to detect power quality issues and reduce unplanned downtime.
- Data Centers & Critical Facilities – Continuous measurement of active/reactive power, power factor, and harmonic distortion on UPS feeds and PDU inputs.
- Commercial Buildings & Campus Facilities – Tenant sub-metering, energy cost allocation, and LEED/ISO 50001 compliance reporting.
- Water & Wastewater Treatment – Monitoring pump station feeders and variable-frequency drive (VFD) loads for energy optimization.
- Oil & Gas / Petrochemical – Feeder-level energy accounting in hazardous-area switchgear lineups (when installed in appropriate enclosures).
- Utilities & Substations – Revenue-grade or near-revenue-grade metering at distribution switchboards.

Why Engineers Specify This Model
- Revenue-Grade Accuracy – Class 0.5S energy measurement satisfies utility billing and ISO 50001 sub-metering requirements without a separate revenue meter.
- Comprehensive Power Quality Data – THD measurement on all voltage and current channels enables proactive identification of harmonic sources before they damage equipment.
- Open Protocol Communication – Native Modbus RTU over RS-485 integrates directly into SCADA, BMS, and EMS platforms (Ignition, Wonderware, EcoStruxure) without proprietary gateways.
- Scalable I/O – Configurable relay outputs support demand-response signaling, alarm annunciation, and kWh pulse output for third-party energy management systems.
- Proven Field Reliability – The PowerLogic CM/CVM platform has millions of installed units globally across industrial, utility, and commercial segments.
- Compact Form Factor – Panel-mount design fits standard switchboard and MCC door cutouts, minimizing retrofit complexity.
Complete System Bill of Materials
For a fully functional metering installation, engineers typically specify the following alongside the CM4250:
- Current Transformers (CTs) – 5 A secondary, accuracy class 0.5 or better (e.g., Schneider Electric ACTI9 or equivalent)
- Potential Transformers (PTs) – Required for systems above 690 V L-L
- RS-485 shielded twisted-pair cable (Belden 9841 or equivalent)
- Modbus RTU to Ethernet gateway (e.g., Schneider Electric EGX100 / EGX300) – if Ethernet SCADA integration is required
- 24 VDC auxiliary power supply – if panel bus power is unavailable
- DIN rail mounting hardware or panel cutout template (supplied with unit)
- EcoStruxure Power Monitoring Expert (PME) software license – for centralized energy dashboards and reporting
Compliance & Industry Standards
- IEC 62053-22 – Class 0.5S active energy metering
- IEC 61557-12 – Performance requirements for measuring instruments
- IEC 61010-1 – Safety requirements for electrical equipment

Application-Specific FAQ
Q: Can the CM4250 replace a revenue meter for utility billing purposes?
A: The CM4250 achieves Class 0.5S accuracy per IEC 62053-22, which meets the threshold for revenue-grade sub-metering in most jurisdictions. Confirm with your local utility authority before use as a primary billing meter.
Q: Is the CM4250 compatible with EcoStruxure Power Monitoring Expert (PME)?
A: Yes. The CM4250 communicates via Modbus RTU and is a supported device in Schneider Electric’s PME and ION Enterprise platforms. Native device templates are available.
Q: What is the difference between CM4250 and CVM42?
A: CM4250 is the North American catalog designation; CVM42 is the IEC/international catalog designation for the same hardware platform. Specifications and firmware are equivalent.
Q: Can I integrate this meter into a Siemens or ABB SCADA system?
A: Yes. Modbus RTU is an open standard. The CM4250 register map is publicly documented and compatible with any Modbus master, including Siemens WinCC, ABB System 800xA, and Ignition by Inductive Automation.
Q: What CT ratio should I use?
A: The CM4250 accepts 1 A or 5 A CT secondaries. Select a CT primary rating that matches your feeder’s full-load current. For best accuracy, operate the CT at 50–120% of its rated primary current.
Q: Do you provide installation support?
A: We provide documentation packages including wiring diagrams, Modbus register maps, and configuration guides. For on-site commissioning support, contact us to discuss options.
