Electricity energy meter with built-in internal WI-FI antenna 3F+N FOX ENERGY 3WI-MEF3-OPTI-400 WI-MEF-3-OPTI-400

Intelligent energy consumption monitoring in your home or business

This three-phase FOX ENERGY 3WI-MEF3-OPTI-400 electricity meter is an advanced tool for monitoring energy consumption, designed for both professionals and end-users. Thanks to the built-in Wi-Fi antenna, the device provides remote access to measurement data, allowing for current control over energy consumption and cost optimization. The meter is ideal for home installations, especially in combination with photovoltaic systems or heat pumps, but will also work well in commercial facilities.

Precision and reliability of measurement

The device is characterized by high measurement accuracy – 1% for the meter and 0.5% for the measuring transducers. Transducers with a primary current of 40 A allow monitoring of loads with different power levels. Mounting on a 35 mm rail (2 modules) ensures easy integration with existing electrical infrastructure. This makes installation quick and does not require complicated work. Wires with a diameter of up to 10 mm can be connected without problems, and screw terminals provide a secure connection for wires with a cross-section of up to 2.5 mm² (stranded) or 4.0 mm² (solid).

Functions and possibilities

The meter not only records electricity consumption but also monitors key network parameters – voltage, current and power. The meter constant of 1000 imp/kWh ensures accurate readings. Thanks to Wi-Fi transmission, data is available in real time via a mobile application or web browser. The device operates in a temperature range of -20°C to +50°C and has an IP20 protection class, which guarantees its reliability in various environmental conditions. The device's own power consumption is minimal – below 2W – which means no impact on overall energy consumption. The device complies with European standards confirmed by the CE marking.
