FAQs
For installation, mount the DH324NGK in a suitable indoor enclosure with a NEMA 1 rating to protect against dust and incidental moisture. Ensure mounting clearances for service access, accommodate a 30 inch length and 18 inch width footprint, and plan wiring routes for three-pole four-wire configurations. Use the neutral-fused design to simplify wiring and fuse placement, and verify UL Listed compliance with local electrical codes.
The DH324NGK supports a three-pole, four-wire setup with fusible protection and neutral. Wire size ranges from #6 AWG to 250 kcmil Cu/Al, enabling flexible connections for motors and feeders. Use Class H fuses per the application and ensure the fuse configuration matches the load requirements. The neutral conductor is integrated, simplifying multi-wire branch circuits in control panels.
Yes, the DH324NGK is rated for 240V and supports multiple HP ratings: up to 15 HP, 25/15 HP, and 60/40 HP for different voltage and drive conditions (1P/3PH as Std/TD/250 Vdc). This makes it suitable for a range of industrial motors and conveyors. Verify the exact HP rating against your motor nameplate and system voltage for correct protection sizing.
The DH324NGK carries UL Listed certification and NEC barrier compliance, with a NEMA 1 enclosure rating for indoor protection.
