WRN-22-0,03, Residual current relay

Code: P14211.

  • Usefull diam.(mm): 22
  • IΔn (A): 0,03 A
  • Delay: 0,02 s
  • Mounting: DIN rail

INFORMATION

Description

  • The WRN-22 relay is an residual current relay with a built-in residual current transformer, with a diameter Ø 22 mm
  • DIN 46277 Symmetrical profile coupling (EN 50022)
  • The leakage is detected by means of sampling the residual current intensity and calculating its true root mean square (TRMS)
  • Detection of the presence of voltage with LEDs
  • TEST button.

Applications

The WRN-22 residual current protection is a very interesting solution for small-scale installations with reduced space.
