What is the Wago 855-405/250-209?
Short description:
WAGO's plug-in current transformers for billing measurement (855 Series) 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 purposes in Germany (MessEG).
Features:
Screwless CAGE CLAMP ® connection technology
Several mounting options available
Vibration- and shock-resistant
High mechanical retention forces
High current-carrying capacity
Continuous overload of 120 % the nominal primary current
Low-voltage current transformer for operating voltages up to max. 1.2 kV
For 690 V power networks
Accessories: 879-3040; Energy Meter; with Push-in CAGE CLAMP ® and lever; transformer connection (2PUCT)
