Product Overview

Our Energy Measurement Products

Energy Meters (MID)

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.

Your Benefits:

  • Compliance with the MID Directive 2014/32/EU allows consumption billing applications
  • M-Bus and Modbus RTU interface and two S0 pulse outputs
  • Push-in CAGE CLAMP® and lever save time at every stage
  • Real space savings with 2 DU: 35 mm (2PUCT) and 4 DU: 72 mm (4 PU and 4 PS)
  • Full transparency with an illuminated full-format display
  • Intuitive configuration with touch-sensitive controls and configuration app via Bluetooth®

3-Phase Power Measurement Modules

The power measurement modules in a DIN-rail mounting enclosure offer the ideal solution for measuring currents and voltages in a three-phase supply network remotely from the control level.

Your Benefits:

  • Various device variants for optional connection of current transformers or Rogowski coils
  • Slot for microSD cards for storing measurement data
  • Compact DIN-rail-mount enclosure
  • Communication via Modbus RTU and pulse output

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

Plug-In Current Transformers for Billing Measurement

Plug-In Current Transformers for Billing Measurement

Plug-in current transformers for billing measurements are inductive, single-conductor current transformers. Due to the measurement principle used, these current transformers are exclusively designed for AC network applications.

These plug-in current transformers comply with the conformity assessment procedure (module D) and can be used for billing.

Your Benefits:

  • Readily combinable with the energy meter with transformer connections
  • Screwless CAGE CLAMP® connection technology
  • Approved for billing purposes

Plug-In Current Transformers with CAGE CLAMP® Connection Technology

WAGO’s plug-in current transformers are suitable for round conductors and current bars. They are available for primary currents from 50 to 2500 A.

Your Benefits:

  • 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

WAGO’s plug-in current transformers are available in two sizes with up to 64 A of primary rated current and the proven picoMAX® connection technology.

Your Benefits:

  • Easy secondary cable installation via pluggable picoMAX® connection technology
  • Space-saving use directly above the circuit breaker
  • UL listed
  • Convert 35 A or 64 A to 1 A
  • Flexible mounting options via separately available mounting carrier

Split-Core Current Transformers

WAGO’s split-core current transformers are ideal for retrofitting existing systems and have the great advantage of being mountable without interrupting the measurement line.

Your Benefits:

  • A split measurement core allows installation without interrupting the primary conductor
  • Pre-assembled secondary cable
  • Easy and cost-effective installation via cable ties

Rogowski Coils

The Rogowski coils are closed air coils with a separable coil body and a non-magnetic core, which reliably convert alternating currents.

Your Benefits:

  • 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
  • Ready for worldwide use in many industries, thanks to UL listing
  • No limitation of the primary current, since saturation effects do not occur

Current and Voltage Tap

The current and voltage tap is a combination of current transformer and voltage tap. It can be easily and quickly mounted in the jumper slot of the high-current rail-mount terminal blocks.

Your Benefits:

  • Power data can be directly tapped into the power supply
  • Complies with accuracy class 0.5 for exact measurement results
  • Fused voltage path protects downstream measurement devices
  • Integrated short circuit option

Voltage Taps for Insulated Conductors and Current Bars

Voltage taps easily and safely tap the measurement voltage in existing systems. Conductor contact is made via IDC connection for reliable voltage tap-off.

Your Benefits:

  • Integrated fuse to protect downstream measurement devices
  • Suitable for insulated conductors up to a cross-section of 16 mm²
  • Quick and easy mounting on current bars via clamp mount or M6/M8 mount
