Chip Auto PPTC
Features：Provide dual protection for over-current & over-temperature generated after the motor stalling,Protection lifetime is more than 2000 times,Rapidly cool the motor after stalling protection,Protection time can be adjusted and set according to the customers’ requirements,Configuration and dimension can be customized according to the allowed motor inner space,No electromagnetic noise,Outstanding anti-vibration ability,Operation temperature: -40℃～85℃/125℃production.
IH=Hold current: maximum current at which the device will not trip at 25℃ still air.
IT=Trip current: minimum current at which the device will always trip at 25℃ still air.
Vmax=Maximum voltage device can withstand without damage at rated current.
Imax=Maximum fault current device can withstand without damage at rated voltage.
Max Time-to-trip=Maximum time to trip(s) at assigned current.
Pd max=Maximum power dissipation: maximum power dissipated by the device when in state air environment.
Rmin=Minimum device resistance at 25℃ prior to tripping.
Rmax=Maximum device resistance at 25℃ prior to tripping.
R1max=Maximum device resistance at 25℃, of device one hour after being tripped the first time.
