Plug-in current transformers

6 March 2013 Passive Components

WAGO’s 855 Series plug-in current transformers are equipped with screwless connection technology and are available for various primary currents up to 1000 A. They are UL recognised components suitable for 230 V, 400 V and 690 V low-voltage applications, up to a maximum operating voltage of 1,2 kV.

The 855 Series transforms rated primary currents into electrically isolated secondary currents up to 1 A with a measuring accuracy of 1%. They can be used in operating temperatures ranging from

-5°C to +50°C and may be permanently loaded with up to 120% of the nominal current.

Cage clamp connection technology provides screwless termination of conductors ranging from 0,08 to 4 mm² (AWG #28–#12). Conductors can be terminated from both the front side and the rear side of the transformers. The plastic housing is extremely robust and can be mounted in four different ways: on round cables, on copper current bars, on mounting plates and, depending on the version, on carrier rails.
