Current Transformers and Voltage Taps

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

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

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

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

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)

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

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

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

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 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
