W60AB measuring current transformer
Measuring current transformers of the
W…AB series
W…AB series
Product description
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.

of IEC 60044-1.
Installation instructions
• 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!
Device features
