TR42CMB | Orion Italia TR42CMB | Rơ le giám sát TR42CMB | Đại lý Orion Italia Vietnam

The TR42 is a temperature monitoring, control and sensor relay (transformer protection 49 relay) for 3 phases cast resin / dry type transformers of any voltage (kV) and power level (kva), Its main functions are to execute actions in real time according to the temperature sensors of the transformer windings and the customized programming, such as on / off the cooling fan, alarm or trip. Communication port RS485 included.

Our transformer protection relay (49 relay) as a temperature monitoring of dry type or cast resin transformer, with 4 PT100 sensor and fan control help on hot days or overcurrent scenarios to achieve more kva, avoiding over temperature. 3 phase, electrical transformers on > 10 kV applications, indoor or outdoor. A great alternative to ptc sensor solutions.  100% compatible with TR-42S1 & TR-42C1
