Remarks Item description:
Short description:

WAGO's Rogowski coils are closed-air coils featuring a non-magnetic split core that can be connected to a Rogowski Signal Conditioner (857-552).

Easy installation of the Rogowski coils allows existing systems to be retrofitted without time-consuming installation or process interruption.

Rogowski technology allows the coils to measure a wide primary current range without loss of accuracy because there are no saturation effects.

Features:
  • Rated insulation voltage: 1000 V Cat. III/600 V Cat. IV
  • Accuracy class 1 per EN 61869-2
  • IP67 degree of protection
  • Measurement coil diameter: 70, 125 or 175 mm
  • Length of signal lines: 1.5 m or 4.5 m
  • Ambient operating temperature: -40 +80
  • Sealable bayonet connector
  • Fixing lugs for cable ties



Insulation voltage: 1000 Veff AC (Cat. III); 600 Veff AC (Cat. IV)

Output signal voltage: (bei 50 Hz)
