Product FAQs
4 answersHow should I use the 400A rating when selecting the Schneider Electric NJHN36000S40AB?
The 400A rating is the switch's current rating. Use it to guide selection against the circuit load, and coordinate the installation with conductor sizing and circuit overcurrent protection.
Can I use this switch on an AC circuit below 600VAC?
Yes. The 600VAC rating sets the upper AC voltage limit for selection, so the circuit's operating voltage must be at or below 600VAC.
How should I handle a neutral conductor when installing this switch?
Use the switch's three poles for the phase conductors and route any required neutral separately. This keeps the neutral separate from the phase-switching connections.
What does the pole count mean when planning the switched conductors?
The three poles represent three switched conductor paths, one for each phase of a 3-phase circuit. Account for all three phase conductors in the switching layout.
