*1. The NL3 has a capacitor and resistor for the protection of the built-in SCR. Therefore, the NL3 has leakage current.
*2. The NL3 requires a current of 30 mA for circuit protection.
        If the load current is less than 30 mA, connect the bleeder resistance R in parallel with the load as shown below so
        that the total current of the load circuit will be 30 to 300 mA.
        Obtain R from the following formula.

Make sure that the permissible power of the resistor is sufficient.
