400V Three-Phase Digital Energy Meter with Class 1 Accuracy – Precise Measurement, Quick Installation
Your electricity bill doesn’t lie — but your meter might. If you are monitoring consumption for a warehouse, commercial premises, or a multi-unit building, you need a three-phase digital meter you can rely on. This unit is designed to prevent pulse loss, withstand extreme temperatures, and install effortlessly into your existing distribution board.
Note: Operating voltage is AC 230V/400V (standard three-phase system), fully compatible with 380V/400V electrical grids across Europe.
Why choose this model? (Key Benefits):
- Class 1 Accuracy — Maximum error of ±1%, suitable for billing purposes and energy audits, not just internal monitoring.
- 6+1 Digit LCD Display — View your kWh consumption at a glance without having to squint or guess the final digit.
- DIN Rail Mounting — Fits into any standard distribution board in minutes, requiring no complex modifications.
- 100A per phase — Capable of handling industrial installations, large commercial spaces, and residential blocks without limitations.
- Low Self-Consumption ≤2W / 10VA — Operates continuously without adding a noticeable load to your installation, even after years of use.
- Operating Temperature -20°C to +50°C — Performs reliably in outdoor enclosures or unheated spaces during winter months.
- Pulse Output 400 imp/kWh — Connects directly to SCADA systems, telemetry, or automation platforms without the need for additional converters.
Performance and Specifications
The advanced digital measurement technology eliminates the mechanical drift typical of traditional meters, ensuring values remain precise regardless of how many years it has been in service. The dual-frequency 50/60Hz and AC 230V/400V compatibility make it suitable for both local grids and installations using equipment imported from outside Europe. Its compact design of 3.97 × 2.99 × 2.55 inches ensures it takes up minimal space on the DIN rail, leaving room for other essential components in your panel.

Frequently Asked Questions
Is this compatible with standard three-phase electrical grids?
Yes. It operates at 230V/400V and 50Hz, matching the standard parameters for national grids. No adapters or transformers are required.
Does it mount directly onto a DIN rail?
Yes, it clips directly onto the standard DIN rail found in any electrical distribution board. The process takes only a few minutes and requires no special tools.
What does Class 1 accuracy mean in practice?
It means the maximum measurement error is ±1% under nominal conditions. This level of precision is sufficient for internal billing, energy audits, and official reporting.
Can I connect this meter to an automated monitoring system?
Yes. The 400 imp/kWh pulse output is compatible with SCADA systems, telemetry, and any automation platform that accepts a standard pulse input.
Is 100A sufficient for a small industrial warehouse?
It depends on your installed power. At 400V three-phase, 100A per phase provides an apparent power of approximately 69 kVA — sufficient for the majority of medium-sized commercial and industrial spaces.
