Item no. 855-9450/2000-1751

Rogowski coil; Primary rated current 4000 A; Output signal 22.5 mV per kA; Cable length 4.5 m; Feedthrough for measurement conductor 175 mm

Description

Short description:

WAGO's Rogowski coils are closed-air coils featuring a non-magnetic split core that can be connected to WAGO products (857-552; 750-495/000-002; 2857-570/024-000).

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

Features:
  • Rated insulation voltage: 1000 V Cat. III/600 V Cat. IV
  • Accuracy class 0.5 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 °C
  • Sealable bayonet connector
  • Fixing lugs for cable ties

Note:

Die Angabe des primären Bemessungsstroms bezieht sich auf die Kombination mit den WAGO-Modulen (857-552 und 750-495/000-002).

Die Rogowski-Spulen können über einen weiten Primärstrombereich ohne Genauigkeitseinbußen Ströme bis zu 10.000 A erfassen, da es bei dieser Technologie keine Sättigungseffekte gibt.

Die Anforderungen für die Normen EN 61869-1, EN 61869-2, EN 61869-6 und EN 61869-10 werden nur teilweise erfüllt, da es bei einer Rogowski-Spule grundlegende Unterschiede zu Stromwandlern gibt.
