Single-phase electricity meter FF LE-01 1‑phase 230V 5/45A with drum display

FF LE-01 is a single-phase electricity meter designed for 230V installations with a current range of 5/45A and a mechanical drum display. It measures active energy and provides cumulative kWh readings on a visible rotating drum counter. The meter is intended for domestic and small commercial circuits where a simple, robust mechanical indication of consumption is sufficient and electronic displays or remote reading are not required.

Advantages

The mechanical drum display offers clear, always-on indication of cumulative energy consumption without requiring power for an electronic screen. The meter supports standard single-phase 230V connections and a 5/45A current range suitable for most household and light commercial loads. Its simple design ensures ease of installation and long-term operation with minimal maintenance, making it suitable for retrofit projects and basic metering tasks.

Suitable for

• Residential apartments and houses
• Small shops, offices and light commercial premises
• Retrofit installations replacing older mechanical meters
• Basic energy monitoring where remote reading is not required

Key specifications

• Voltage: single-phase 230 V
• Current range: 5–45 A
• Measurement type: active energy (kWh)
• Display type: mechanical rotating drum counter for cumulative kWh
• Application: domestic and small commercial circuits

How to use

Install the meter in accordance with local electrical regulations and wiring practices, ensuring the supply is switched off before connection. Connect line and neutral conductors to the appropriate terminals and secure the meter mechanically in its enclosure or meter box. After powering the circuit, verify that the drum display rotates when load is applied, indicating energy consumption. Read cumulative energy directly from the drum counter; no configuration or electronic interface is required.

Usage recommendations

For safe and reliable operation, have installation and any maintenance carried out by a qualified electrician. Use the meter in environments within the manufacturer’s specified temperature and humidity ranges and protect it from direct moisture and mechanical damage. For installations requiring remote reading, tariff switching, or advanced consumption analytics, consider electronic meters with communication features instead of a mechanical drum display.
