POSISTOR r for Circuit Protection
Overcurrent Protection 24/30/32V Series
The safety resistor "POSISTOR" is most suited to meet
the requirements of the safety standard short-circuit tests
such as IEC, VDE, BS, UL, CSA, etc., worldwide.
c Features
1. Best suited to meet the requirements of the short-
circuit test. Quick response compared with current
fuse and resistor and error-free operation are
assured.
2. Small size save board space. Capable of being

mounted anywhere because replacement is not
required.
3. Actuates by excessive current during the short-
circuit test to restrain abnormal heat generation
in other circuit components and printed boards.
This state will be maintained until the abnormal
state is removed or power is turned off to reset
the "POSISTOR" to the original state. Surface
temperature of "POSISTOR" is kept low, below a
certain value, during the actuation.
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.
