POSISTORr for Circuit Protection
Overcurrent Protection 125/140V Series
R90E.pdf
Sep.24,2012
"POSISTOR" is a circuit protector whose resistance
value in normal operation is very low and in abnormal
situations like overcurrent or overheating, will be
increased to restrain overcurrent. "POSISTOR" can be
used for overcurrent protection against current fuse
or temperature fuse, due to its ability to return to
its initial condition when overcurrent is removed.
c Features
1. Best suited to meet the requirements for power
supplies and motor protection. Error-free operations
are assured by rush current.
2. Circuit is protected until current is turned off.
3. Restores the original low resistance value
automatically once the overload is removed.
4. Non-contact design leads to long life and no noise.
Durable and strong against mechanical vibration
and shock because it is a solid element.
c Applications
Circuit Protection :
1. Transformers
2. Transistors
3. Fluorescent Lamps
