PTC Thermistor 265V 80° 6R 4,1A
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
