MENNEKES 18662 Modbus TCP Energy Meter for Load Management, 3-Phase 80A, MID Class B, DIN Rail

Direct measurement up to 80 A on a 3-phase 4-wire network, with Modbus TCP over Ethernet and MID Class B accuracy — the MENNEKES 18662 brings precise energy data straight into your load management system.

Overview

The MENNEKES 18662 is a DIN rail-mounted energy meter engineered for load management and sub-metering in industrial and commercial installations. It measures active and reactive energy, power, voltage, current, frequency, and power factor on three-phase systems up to 3x230/400 V AC. Data is transmitted via Modbus TCP over a standard RJ45 Ethernet port, enabling seamless integration with PLCs, building management systems, and energy monitoring platforms.

What stands out

• Direct 80 A measurement — no external current transformers required, simplifying installation and reducing cost.
• MID compliant (EN 50470-1/3) with Class B accuracy for active energy, ensuring billing-grade precision.
• Modbus TCP interface for real-time data access, multi-tariff support, and remote configuration.
• Backlit LCD display for on-site reading of all key electrical parameters.
• Compact 4-module (4TE) DIN rail housing with IP51 front protection, suitable for distribution boards.
• Configurable S0 pulse output for integration with legacy systems or additional monitoring.
