PTC-relay for the monitoring of
dry transformers.
Alarm 1 with relay in closed-
circuit current mode for pre-
liminary warning, releases at
over-temperature at PTC-set 1
and serves at the same time as
functional monitoring.
Alarm 2 in operating current
mode. Thus no wiping signal
occurs when switching on the
supply voltage on.
Additional terminals enable
comfortable wiring from supply
voltage to relays K1 and/or K2.
