Application and description of thermal pellet

General information
The resistor relay type MSF 220 K is particulartly qualified to survey dry transformers. It’s a low-cost construction without the loss of survey safety and reliabiltiy. The rely for the tripping (alarm 2) won’t show any error message during the power activation. An in series set time relay, which operates delayed is not necessary. Due to this, it is possible to install these devices even if the control voltagte is generated by the observed transformer. With the integrated “test”-button, devices and downstreamed systems can be observed easily. Additional terminals allow a comfortable pulling of the control voltage to the relay K1 and/or K2.
