WF Series

Flexible WF… series measuring current transformers are highly sensitive measuring current transformers, which measure AC currents in conjunction with a RCMS460/490 series ground-fault monitoring system and convert them into an evaluable measuring signal. They consist of one flexible WF… measuring current transformer and one RCC420 signal converter. Connection to the respective ground-fault monitor is via a two-wire cable.

Features

  • Flexible measuring current transformer in different lengths
  • Space-saving design, quick installation
  • Easy retrofitting into existing installations
  • Can be installed without the need to disconnect the conductors
  • Connection monitoring WF… measuring current transformers
  • For RCMS460/490 series residual current monitoring systems
  • For RCM420 series residual current monitors
  • Analogue output (U, I) for external measuring devices
  • RCC420 with push-wire terminals (two terminals per connection)

Applications

  • Residual, fault and nominal current monitoring of loads and systems which cannot be switched off
  • EMC monitoring of TN-S systems for “stray currents” and additional N-PE connections in the central earthing point (CEP)
  • Monitoring of PE and equipotential bonding conductors to ensure they are free of current
