*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.
*3. Between current-carrying and non-current-carrying metal parts
Caution: In the interenst of product improvement, specifications are subject to change without notice.
