Description
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 technologySeveral mounting options availableVibration- and shock-resistantHigh mechanical retention forcesHigh current-carrying capacityContinuous overload of 120 % the nominal primary currentLow-voltage current transformer for operating voltages up to max. 1.2 kVFor 690 V power networksAccessories: 879-3040; Energy Meter; with Push-in CAGE CLAMP® and lever; transformer connection (2PUCT)
