Features • Ceramic PTC Thermistors provide overcurrent protection for single-phase motors, transformers etc. as well as electronic circuits (subscriber line interface cards) • The ceramic PTC resistor contrary to PTC's are polymer-based and after repeated cooling returns to its initial resistance value • By responding to inadmissibly high currents and protecting pre-selected temperature limits which have been exceeded; the thermal dissipation from the complete power circuit is limited, as the increased resistance of the current is reduced to a harmless residual value • The PTC resistor must not be exchanged after the maximum temperature has been exceeded, as after a short cooling period, the protective function immediately takes over • Overcurrent and short-current protection • Leaded discs coated • Pitch 5,08mm
