Dear _oleksandr_, I assume, that it is used for a Micromaster (MM braking resistor). The PTC is located that the resistor and its housing may not be the origin of a fire. In section 3.15.3 of the MM4 manual is described which duty cycle the resistor is designed for: The resistor you described is able to handle 2.2kW continuous or 44kW for 12s and a 228s subsequently break. |
With best regards, |
