Product Description Ordering Key
DTA 01 C 230
DTA01, DTA02, PTA01 and PTA02 are precise thermis- tor monitoring relays.
They can be used to monitor the temperature of the coils of a motor with built-in PTC’s. The alarm status of the relay can be reset by
either an external contact or an internal button (DTA02, PTA02).
The test button allows the simulation of the fault condi- tion (DTA02, PTA02).
The red LED indicates the alarm status.
