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 CAGE CLAMP® Connection Technology
- 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
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
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 Transformer 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
