## **Finger-safe, spring-up terminals reduce wiring time.** 

Ring terminal tabs can be installed easily, and screws are held secure. 

## **Retractable Actuator** 

The actuator retracts when the circuit protector turns on. Inadvertent operation, due to touching the actuator, is prevented. Status of the circuit protector can easily be confirmed by viewing the position of the actuator.

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. 

**==> picture [132 x 122] 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. 

## **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.
