POSISTOR r for Circuit Protection
Overcurrent Protection 16V Series
D max.
This low-voltage, low-resistance type "POSISTOR" is
a circuit protector whose resistance value in normal
operation is very low and in abnormal situations like
motor lock or short circuit, will be increased to
restrain overcurrent. This "POSISTOR" is most
suitable for low-voltage circuits.

1. Best suited to meet the requirements for power
supplies and motor protection. Error-free operation
is 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.
