NC1V Circuit Protectors
Time Delay Curve and Ambient
Temperature
NC1V circuit protectors employ an electromagnetic tripping
system, where the rated current (trip current) is not affected
by ambient temperatures. But the time delay may vary with
the oil viscosity in the oil dash pot. Lower oil viscosity at
higher temperatures results in a shorter delay, whereas at
lower temperatures the delay will be longer.
Temperature Correction Curve
The time delay curves on the preceding page are measured
at 40°C. With reference to the following curves, time delays
can be corrected according to ambient temperature.
The time delay is based on an ambient temperature of
40°C. Time delays at other temperatures are corrected
according to the temperature correction curve. The time
delay of the instantaneous time delay curve (S) is not
affected by the ambient temperature.
W h e n o p e r a t i n g t e m p e r a t u r e
exceeds 40°C, derate the rated
current by multiplying the derating
factor shown on the right.

Inertia Delay
Inertia delay is designed not to trip on a non-repeating
single pulse of 20 times the rated current (peak value) for a
duration of 8 ms. In addition, circuit protectors equipped
with inertia delay do not respond to high inrush currents
caused by transformer or lamp loads, but perform the
specified interruption on the subsequent overcurrents.
Inertia delay is available on AC circuits, and is not available
with the series trip curve S (instantaneous).
Voltage Drop Due to Coil Resistance or Impedance
The internal resistance or impedance of a circuit protector
tends to be larger for a smaller rated current. Therefore,
when circuit protectors of a small rated current are used,
voltage drop should be taken into consideration. Internal
resistance also varies with time delay curves, which should
also be considered during installation.
