Power Measurement with the 3-Phase Power Measurement Module (2857-570/024-001)

Current/Voltage Signal Conditioners and Power Measurement Modules

Besides current and voltage signal conditioners which record DC and AC currents and voltages, this impressive range also includes a power measurement module that can measure current and voltage in parallel, convert them to power and output them as an analog standard signal.

Your Benefits:

  • Measure DC or AC voltages up to 300 V in a width of just 6 mm
  • Common the supply voltage via jumpers that can be used across the entire range
  • Versatile configuration

An All-in-One Solution from a Single Source

WAGO Current Transformers and Energy Meters (MID)

Plug-in current transformers for billing measurement join WAGO’s range of current and energy measurement solutions. These transformers comply with the conformity assessment procedure (module D) and are perfect for combination with the new WAGO Energy Meters (MID) to form a complete solution. A quick-mount kit allows easy, cost-effective installation. A large number of mounting options give users tremendous flexibility. The new plug-in current transformers are used in applications where the current of large consumers cannot be measured directly. A real-world example is measuring manufacturing machines’ energy consumption in order-related production or when individually billing the energy consumption of each tenant in distributed properties.

Plug-In Current Transformers with CAGE CLAMP® Connection Technology

The Benefits for You:

  • Screwless CAGE CLAMP® Connection Technology
  • Quick-mount kit for easy and cost-effective installation
  • Tremendous versatility thanks to several mounting options
  • Easy transformer short-circuiting via redundant secondary terminals S1 and S2
  • UL listed

Plug-In Current Transformers with picoMAX® Connection Technology

The Benefits for You:

  • Easy secondary cable installation via pluggable picoMAX® Connection Technology
  • Space-saving assembly directly above the circuit breaker, thanks to side latches for optimum serial mounting
  • UL listed

Split-Core Current Transformers

The Benefits for You:

  • Compact and separable split-core current transformers – ideal for retrofitting existing systems
  • No current path interruption
  • Easy and cost-effective installation via cable ties
  • Transformer leg (855-5xxx) can be completely removed if space is tight

Rogowski Coils

WAGO’s 855 Series Rogowski Coils feature a closed-air coil with a non-magnetic split core and reliably convert AC currents.

The Benefits for You:

  • Reduced footprint – ideal for measuring high currents via split core
  • Easy to use via bayonet lock and anchor points for cable ties
  • Higher security via sealable bayonet lock
  • Direct connection of Rogowski coils to the 3-Phase Power Measurement Module (750-495/000-002)
  • Ready for worldwide use in many industries, thanks to UL listing

Current and Voltage Tap

A combination of current transformer and voltage tap, the current and voltage tap can be quickly and easily mounted in the jumper slot of the 95 mm2 (4/0 AWG) high-current through terminal block (285-195).

The Benefits for You:

  • Power data can be directly tapped on the power supply
  • Integrated 25 A/1 A current transformer
  • Complies with accuracy class 0.5 per EN 61869-2 for exact measurement results
  • Fused voltage path protects downstream measurement devices

Voltage Taps for Insulated Conductors

WAGO’s 855 Series Voltage Taps easily and safely tap the measurement voltage in existing systems. Conductor contact is made via IDC connection for fast voltage tap-off.

The Benefits for You:

  • Safely tap the measurement voltage in no time
  • Tool-free insulation displacement connection guarantees secure installation.
  • 2 A fuse possible, 5 x 25 mm
  • For insulated conductors up to 16 mm2 (6 AWG)
