Current Transformers and Voltage Taps

Anywhere high currents are measured and processed, WAGO's current transformers are your first choice. Voltage taps also easily and safely tap the measurement voltage in existing systems.

Your benefits:

  • Safe, secure wiring with CAGE CLAMP® Connection Technology
  • Full range of products for new systems, as well as for retrofitting existing installations
  • Coordinated components for your energy data management

Product Overview

Rogowski Coils

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

Advantages:

  • 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

Plug-In Current Transformers with picoMAX® Connection Technology

Advantages:
  • 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

Advantages:
  • Compact 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

Plug-In Current Transformers with CAGE CLAMP® Connection Technology

Advantages:
  • 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

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 (IDC) guarantees secure installation
  • 2 A 5 x 25 mm fuse possible
  • For insulated conductors up to 16 mm2 (6 AWG)

Voltage Taps for Busbars

The Benefits for You:

  • Fast, easy installation on a live busbar with clamp mount or M6/M8 mounting
  • Various marking options for clear identification
  • Universal conductor termination via Push-in CAGE CLAMP® connection technology
  • Fused voltage path protects downstream measurement devices

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 250 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
