## 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. 

**==> picture [150 x 138] intentionally omitted <==**

**----- Start of picture text -----**<br>

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. 

## Inertial Delay 

Inertial 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 inertial delay do not respond to high inrush currents caused by transformer or lamp loads, but perform the specified interruption on the subsequent overcurrents. Inertial delay is available on AC circuits, and is not available with the series trip curve S (instantaneous).

## Relay Trip (Voltage Trip) 

at 25°C 

## 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.

- The padlock is not supplied with the padlock attachment and must be supplied by the user. 

- The total weight of the padlock can be a maximum of 45g. Make sure the padlock weight does not exceed 45g, otherwise the NC1V circuit protector may be damaged. 

- Applicable Padlock Size 

Note: NC1V circuit protectors with auxiliary/alarm contacts cannot be used with mounting brackets. 

## Installing the NC9Z-PW1 Marking Plate 

Available for 2-pole circuit protectors only. 

For use on 1-pole circuit protectors, break the marking plate into two halves.

## Installing the NC9Z-LK1 Padlock Attachment 

- ➀  Pull down the retractable actuator, and install the padlock attachment on the circuit protector. 

- 1-pole: Insert the pin into the holes under the retractable actuator. 

- 2- or 3-pole:  Insert the pin into the holes in the center of the circuit protector. 

## Safety Precautions 

- When using the padlock, do not use the NC1V circuit protector where it is subject to vibration or shock, otherwise failure or damage may result. 

- Do not apply a force of more than 50N on the retractable actuator, otherwise the actuator will be damaged. 

- When using three or more 1-pole NC1V circuit protectors adjacently, facilitate installing the padlock attachment by providing a clearance of 6mm minimum between the protectors, or by using the tweezers or flat screwdriver.
