No flames, no explosion. After fusing, the resistance value Is 100K. * The interruption mechanism for resistance values <10R and resistance values >max. r ange is not clearly defined, also for other voltage. Need to be tested in the final application

File Nr. 3200.18-450.121.14 | Revision: 202104 Beside fusible, this resistor also acts as in-rush current limiting for normal operation. NOTE: The voltage shown in the below table, is the net voltage across the resistor. The generator open voltage will be higher due to the generator’s internal impedance (12[Ω]).
