Typical Connection
ADW2xx is a rail-mounted multi-loop power instrument: one unit measures up to four three-phase circuits at the same time through external open-type current transformers, so a whole distribution box can be metered by a single device.

Built-in functions
- Several outgoing circuits metered by one instrument against one voltage reference
- Open-type CTs clamp over the cable, so the busbar or cable does not have to be removed
- Energy, power, demand and harmonic data per loop for sub-building sub-metering
- Dry-contact inputs for breaker status, relay outputs for alarm or load control
Before you request a quote
- Number of current loops to meter
- Cable diameter or busbar cross-section through the CT window
- Maximum current per loop
Send the number of circuits, the cable or busbar size and the maximum current per loop; we confirm the instrument type and the matching CT perforation size within one working day.
