Type of protection
RT II
Maximal contact load at AC 1 with 230V:
2 contacts with 6A each
Gold contacts with 4-6μm layer thickness
When switching high voltages and currents the layer of
gold is already destroyed after a few switching ope-
rations. Once the gold layer is damaged due to the
switching of high loads, this contact must not be used
anymore for signal and control current circuits.
Then safe contact making is only possible at high loads
with the formation of sparks.
