WF1800CH-2 Messstromwandler Flexibel

The flexible measuring current transformers of the WF... series are highly sensitive measuring current transformers that convert AC currents into an evaluable measuring signal in conjunction with residual current monitors of the RCMS460/490 series.

They consist of a flexible W...F measuring current transformer and an RCC420 signal converter.

The connection to the respective residual current monitoring devices is made via a two-core cable.

Features and functions:

- Flexible measuring current transformer with various lengths

- Space-saving and quick installation

- Simple retrofitting in existing systems

- No need to switch off the system for installation

- Connection monitoring measuring current transformer WF..

- For residual current monitoring systems of the RCMS460/490 series

- For residual current monitoring devices from the RCM420 series

- Analog output (U, I) for external measuring devices

- RCC420 with spring terminals (two terminals per connection)

Technical features:

- Measuring loop 1800mm, incl. RCC420-2

- Measuring loop diameter: 572mm

- Supply voltage Us DC 70...300V / AC 42...460 Hz, 70...300 V

- Measuring range: 100mA...20A

- Rated frequency: 42...2000Hz

- Rated burden: 68 Ohm

- incl. 1 pc. Mounting clip for housing XM420

Applications:

- Differential, fault and rated current monitoring of loads and systems that 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 PA conductors for absence of current.
