What is the Wago 879-3020?
Short description:
Crucial for trimming costs, comprehensive energy measurement is necessary to optimize energy consumption. WAGO’s portfolio has energy meters that simplify this task while offering several key advantages. They use push-in connection technology with a lever, making them connect quickly and easily. The devices have a width of just 72 mm for direct measurement. These slim profiles save a tremendous amount of control cabinet space. In addition to the values for active and reactive energy, the energy meters also record the mains frequency, as well as current, voltage and power for all phases. And the user can conveniently scan all of these energy characteristics at a glance on a large, illuminated display.
Features:
Push-in CAGE CLAMP ® and lever save time at every stage
Real space savings: 72 mm wide (4PS)
Measurement of supply and purchase
Energy measurement in four tariffs
The communications pro: M-Bus/Modbus ® interface and two S0 pulse outputs
Full transparency at a glance: display energy quality characteristics on an illuminated full-format display
Intuitive configuration: touch-sensitive controls and configuration app via Bluetooth ®
