Data sheet | Item number: 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 www.wago.com/855-9450/2000-1751 

## Item description 

## Short description: 

These Rogowski coils are closed-air coils featuring a non-magnetic split core that can be connected to WAGO products (857-552; 750-495/000002; 2857-570/024-000). 

Easy mounting 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) Protection type: IP57 

Measurement coil diameter: 70, 125 or 175 mm 

Length of signal lines: 1.5 m or 4.5 m 

Surrounding air temperature: −40 … +80°C 

Sealable bayonet connector 

Anchor points for cable ties 

## Note: 

The specifications for the primary rated current refer to a combination with the WAGO Modules (857-552 and 750-495/000-002). 

Rogowski technology allows the coils to measure a wide primary current range of up to 10,000 A without loss of accuracy, because there are no saturation effects.

The requirements for standards EN 61869-1, EN 61869-2, EN 61869-6 and EN 61869-10 are only partially met, as there are fundamental differences with current transformers for a Rogowski coil.
