The Orno WE-520 measures three-phase active energy on 3×230V/400V~ networks at 50/60Hz. It has a base current of 5A, a maximum current of 80A, and a minimum starting current of 0.25A. The 800 imp/kWh pulse output allows integration with building management systems and remote monitoring equipment.

Compliance with the MID directive (2014/32/EU) certifies the meter for use in legally relevant metering applications. The Class B measurement accuracy and IP51 degree of protection suit standard indoor distribution panels. The unit occupies 4.5 DIN modules.
