Three-phase electric energy meter MCX4-31XCT series

single-phaseDIN railwith current transformer

Overview
MCX4-31XCT is a MID-certified energy meter with M‑Bus-compatible communication and Modbus RS485 interface, designed for connection via current transformers (CT). Suitable for measurement on single-phase (up to 3), three-phase or four-phase networks, with pulse output and centralized telemetering capability.

Features

• Electrical:
  • Energy meter for up to 3 single-phase networks, three-phase or four-phase systems
  • Connection via current transformers (CT) / 1A or /5A
• Communication:
  • Modbus RS485
  • Pulse output
  • Clear interface and intuitive menu
• Physical:
  • DIN-rail mounting
  • Housing width 4 modules (72 mm)
  • Front panel protection rating IP54

Benefits and applications
The MCX4-31XCT combines M‑Bus-compatible communication and CT connection to provide a MID-certified metering solution for commercial, industrial and multi-site installations that require consumption allocation and centralized remote reading. It is suitable for integration into energy management and multi-energy systems, load analysis and electrical performance optimization.
