Contador de energía trifásico digital WAGO 879-3020 4PS 65 A conforme MID

The WAGO 879-3020 4PS is a high-precision digital three-phase energy meter designed for direct connection in DIN rail installations. With a maximum current of 65 A and MID compliance (Module B + D), it ensures accurate billing-grade measurement of active energy (kWh) in commercial and industrial applications. The clear LCD display with backlight provides easy reading of consumption data, while the S0 pulse output enables remote monitoring and integration with energy management systems.

Advantages

MID-certified for legal metrology (Module B + D) ensures compliance with European standards for billing purposes. Direct connection up to 65 A eliminates the need for external current transformers, simplifying installation. The compact 2 TE (35 mm) design saves space on the DIN rail. Low internal power consumption (<1 W per phase) contributes to energy efficiency. Wide operating temperature range (-25 to +55 °C) makes it suitable for various environments.

Suitable for

• Sub-metering in commercial buildings
• Industrial energy monitoring
• Renewable energy systems (e.g., solar PV)
• Billing applications requiring MID compliance

Recommendations

For optimal performance, install the meter in a clean, dry environment within the specified temperature range. Use appropriate circuit protection (e.g., fuse or circuit breaker) upstream. The S0 pulse output can be connected to an energy management system or data logger for remote monitoring. Ensure compliance with local regulations for MID meters.
