FAQ for G3NB-240B-1 DC5-24V
What heat sink do I need for 40A?
Substantial heat sink required. Power dissipation: 1.6V × 40A = 64W. Consider forced air cooling for high ambient temperatures. Calculate heat sink thermal resistance for your application.
Can I parallel SSRs for higher current?
Not recommended. SSRs don't share current evenly due to voltage drop variations. Use single higher-rated SSR or mechanical contactor for higher currents.
What wire size for 40A?
Use minimum 8 AWG (10mm²) copper wire for 40A. For runs over 3 meters or high ambient, use 6 AWG (16mm²). Follow local electrical codes.
Can this switch three-phase loads?
No, this is single-phase SSR. For three-phase loads, use three single-phase SSRs (one per phase) or dedicated three-phase SSR (G3PE-5 series).
