PTC-relay for the monitoring of dry transformers. Alarm 1 with relay in closedcircuit current mode for preliminary 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.

Changes from T221715 / T221716 to T221717 / T221718 (cURus, monitoring of sensors for short circuit an interrupt activatable, improved test function)
