The MSF 220 V is particularly suitable for the temperature monitoring at dry transformers. 3 PTC-circuits with different nominal response temperatures (NRT) can be connected to this unit, one for controlling a fan (forced cooling) and two for alarms. Each PTC-circuit is monitored for break and short circuit. This reduces the probability of false alarms.
Part number:
