The EPCOS B59155-M140-A70 is a PTC thermistor specifically designed for the thermal protection of windings in electric motors. It features a thermistor pellet with insulating encapsulation and silver-plated, PTFE-insulated AWG 26 litz wires.
Key electrical characteristics include a maximum operating voltage of 30V at 0-40°C and a maximum measuring voltage of 7.5V. The rated resistance is 100W at 2.5V, with an insulation test voltage of 2.5 kV ac. The response time is less than 5 seconds. The operating temperature range is -25°C to +180°C when V=0, and 0°C to 40°C when V=Vmax.
This series conforms to DIN 44 081 for nominal threshold temperatures between 90°C and 160°C. The B59155-M140-A70 variant has a nominal trip temperature of 140°C. It can be used in conjunction with Siemens tripping units. The litz wires are color-coded for trip temperature identification, with white/blue indicating 140°C for this model.
