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

New Product

Easy Installation and Configuration

New Compact Energy Meters with Large Displays

Comprehensive energy measurement is necessary for optimizing energy consumption. WAGO’s portfolio now has new energy meters that simplify this task while offering several key advantages. They use Push-in CAGE CLAMP® with levers, allowing them to connect very quickly and easily. The devices have a width of just 72 mm for direct measurement; versions for current transformers are even slimmer at only 35 mm. These widths save a tremendous amount of control cabinet space.

In addition to the values for active and reactive energy, the energy meters also record the mains frequency, as well as current, voltage and power for all phases. The user can see all these energy characteristics at a glance on a large illuminated display. The new energy meters are true communication professionals. All devices have both an M-Bus and a Modbus® interface for users to select from. In addition, two S0 interfaces are available for both energy directions, with the pulse rate adjustable.

Configuration and operation of the new meters are refreshingly straightforward: A large display facilitates operation using the integrated touch-sensitive controls. A configuration app can also be used that communicates with the device via Bluetooth®. With these new energy measurement devices, a wide variety of building and industrial applications can be implemented thanks to the MID declaration of conformity. Applications with consumption billing are also possible.

The Benefits for You:

  • Push-in CAGE CLAMP® and lever save time at every stage
  • Slimline design conserves valuable cabinet space
  • Professional communication thanks to the M-Bus and Modbus® interface and two S0 pulse outputs
  • Full transparency with an illuminated full-format display
  • Intuitive configuration through touch-sensitive controls and configuration app via Bluetooth®
