Auxiliary contacts (i)OF for Acti9 iC60 / Multi9 C60 has operating voltage up to 130VDC (or less for some references).
Disconnecting of DC currents is technically much more difficult than AC currents (which crosses zero level in each period).
An electrical arc is generated during disconnection (opening).
Ability of contacts to break this arc depends on DC voltage, current, distance of contacts in open position and material of contacts.
The current through aux. contacts for iC60/C60 are not tested and certified for disconnection of DC voltage over 130VDC.
So therefore we cannot recommend such usage.
