!Note
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
2. Circuit is protected until current is turned off.
3. Restores the original low resistance value
4. Non-contact design leads to long life and no noise.
