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

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

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

Products

Modern equipment design requires a wide variety of components that can meet diverse challenges: Examples include user- and maintenance-friendliness, low investment costs, safety and availability, and simplicity in design and usage.

Signal Conditioners and Isolation Amplifiers

Isolating, amplifying, filtering and converting: WAGO's JUMPFLEX® Signal Conditioners and Isolation Amplifiers handle a large number of functions in various application areas and provide secure and error-free signal transmission – thanks to a comprehensive range of approvals for worldwide applications.

Power Supply Modules

WAGO’s efficient power supplies always deliver a constant supply voltage – whether for simple applications or for automation with greater power requirements. WAGO offers uninterruptible power supplies (UPS), buffer modules, redundancy modules and a wide range of electronic circuit breakers (ECBs) as a complete system for seamless upgrades.

Relay and Optocoupler Modules

Whether relay sockets or pluggable relay and optocoupler modules – WAGO's array of relay and optocouplers offer a solution for any requirement. Use them in any sector of industry including process technology and power engineering, railway applications and machine engineering, as well as general control cabinet construction.

Interface Modules

WAGO's interface modules offer you safe and maintenance-free connections for flexible signal wiring applications. They connect electronics to electrical systems at the control level and handle signal transmission and distribution on the control and field levels (system, machine).

System Wiring

WAGO's system wiring solutions allow you to wire individual components of your automation application systematically, quickly and easily. As system and control cabinet solutions become more and more complex, this saves time and money on planning, installation and commissioning.

Overvoltage Protection and Specialty Electronics

WAGO's overvoltage protection and specialty electronic products have many uses. Interface modules with specialty functions provide safe, error-free signal processing and adaptation. Our overvoltage protection solutions provide reliable fuse protection against high voltages for electrical equipment and systems.
