Item no. 855-301/050-103

Plug-in current transformer; Primary rated current: 50 A; Secondary rated current: 1 A; Rated power: 1.25 VA; Accuracy class: 3

Description

Short description:

The 855 Series Plug-In Current Transformers are inductive, single-conductor current transformers. Due to the measurement principle used, these current transformers are exclusively designed for AC network applications.

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
  • Can be used in 690 V power networks
  • UL recognized components
