Measuring current transformers of the W…-AB series are measuring current transformers 
which in combination with devices of the RCMA420 resp. RCMS460/423 490 series convert 
AC and DC currents into evaluable measurement signals. Connection to the respective devices 
is via a five-wire or six-wire cable. The CTs can be used in DC, AC, and 3(N) AC systems. If the 
measuring current transformers are to be connected to an RCMS460/490 system, one AN420 
or AN110 power supply unit is required for six measuring current transformers each.

The measuring current transformers of the W35ABP and W60ABP series feature an integra-
ted Mumetal shield.

The measuring current transformers of the W…-AB series comply with the requirements 
of IEC 60044-1.

•  Make sure that all live conductors are routed through the measuring current transformer 

•  Do not route shielded conductors through the measuring current transformer

•  Never route a PE conductor through the measuring current transformer!

•   W20AB…W60AB for AC/DC sensitive 

RCMA420 series residual current monitors

•   W20AB…W210AB for RCMS460 / 490 series 

residual current monitoring systems or for 
RCMA423 residual current monitors

•   W35ABP…W60ABP for RCMS460 / 490 and 

RCMA420 / 423 series residual current 
monitors. Suitable for systems where short-
term system-related load currents occur
