PTC resistance heater 3941 series

compact

PTC resistors combine two technologies: electric heating and temperature limitation. These resistors have a high conductivity at low temperatures, but at a particular value known as the ‘Curie bend’, their resistance increases considerably. This technology allows automatic temperature limitation independently of the supply voltage. Resistor bare, for fitting in a ‘sandwich’ of two metal plates. Supply voltage 120 up to 240V. Connection by leads, reinforced along the first 30mm
