NZR EcoCount SL 3-vaihe-energiamittari, 5(1)A CT, Modbus RTU, MID, DIN-kisko 33420505

The NZR EcoCount SL 33420505 is a MID-compliant 3-phase energy meter designed for indirect connection via current transformers with a 5(1)A secondary. Unlike basic pulse-only meters, it integrates Modbus RTU over RS485, enabling direct integration into building management and industrial automation systems. Its 4-module DIN rail housing and backlit LCD make it suitable for sub-metering in commercial and industrial distribution boards.

Highlights

• MID certified (EN 50470-1/3) for billing-grade active energy measurement, Class B accuracy.
• Modbus RTU (RS485) interface for remote reading and configuration.
• Supports multi-tariff operation (up to 2 tariffs) and two configurable S0 pulse outputs.
• Measures active and reactive energy, voltage, current, power, frequency, and power factor.
• Compact 4-module (72 mm) DIN rail mounting, IP20 protection.

In daily use

Install the meter on a standard DIN rail and connect the CT secondary wires to the 5(1)A inputs. The backlit LCD provides clear local readings, while the Modbus interface allows integration with energy management software. Configure the S0 outputs for pulse counting or tariff switching. The meter operates over a wide temperature range from -25°C to +55°C, suitable for most indoor electrical cabinets.
