Three-phase 4-wire digital electricity meter 20(80)A for DIN rail, kWh consumption measurement

This three-phase energy meter is a precise and reliable measuring device designed for fixed indoor installation. It directly and accurately measures the active energy consumed on three-phase AC networks with a nominal frequency of 50 Hz. The product you will receive is an energy meter. It offers the advantages of easy reading, high reliability, compact size, light weight, attractive design, and advanced technology. Installation is simplified thanks to a standard 35 mm DIN rail. It fully complies with the technical requirements of accuracy class 1 of the national standard GB/T17215.321-2008 and the international standard IEC62053. Its performance is excellent: it offers good immunity to electromagnetic interference, low self-consumption, high precision, high overload capacity, high stability, anti-theft features, and a long service life.

**Operating Environment:**

Ideal for indoor installation in environments where the ambient temperature is between -25°C and +55°C, with a relative humidity not exceeding 95%. The device must be protected from corrosive gases, excessive dust, mold, salt spray, condensation, and insects.

**Installation and Use (for information purposes only):**

Installation must be carried out by a qualified electrician. The meter is mounted on a 35mm DIN rail in a dry, well-ventilated indoor location. It is essential to follow the provided wiring diagram and use suitable multi-strand copper cables. Once correctly connected to the mains, a power indicator light will illuminate. LED indicators (A, B, C) signal the normal presence of each voltage phase. The meter also has a "PULSE" indicator light for detecting power pulses and a "Rev." indicator to signal a reversal of the power direction. In areas prone to thunderstorms, lightning protection measures are recommended. The load capacity must remain within the specified range (0.05 Ib ~ Imax in direct access). When used with current transformers, the reading must be multiplied by the turns ratio. **Package Contents:** You will receive **1 Energy Meter**.
