For building intercom resettable fuse
In the main control room building intercom system, sub control room, to each household on a single machine, each level is to design a self-recovery fuse (pptc), PPTC mOhm resistance value level, does not affect the system normal operation
PPTC overcurrent protection devices commonly used in the security model:
 
1, the plug PTC: WH30-110, WH30-135, WH30-160, WH30-250, WH30-300;
      WH60-110, 1WH60-135, WH60-160, WH60-250.
      WH60-110 is mainly used more often, mostly supply voltage 12V, 5V, consider the special circumstances elect partial pressure.
 
2, SMD common: WH1812-010, WH1812-014, WH1812-110, WH1812-150, WH1812-160, WH1812-260.
        Supply voltage 12V majority.
