FAQs
For installation, plan a three-pole, four-wire configuration with Class H fuses and a fusible-with-neutral setup. Use wire sizes from #6 AWG up to 250 kcmil Cu/Al, and mount in a NEMA 1 painted steel enclosure. Ensure NEC 230.62 barrier compliance is maintained to protect personnel and equipment during maintenance and energization.
The 200 A rating provides robust protection for heavy motor loads, while 240 V supports common industrial motor circuits. This configuration enables higher fault tolerance and coordinated protection with compatible starters, reducing nuisance trips and optimizing energy use across conveyors, pumps, and processing equipment.
Yes. The unit features NEC 230.62 (C) compliant barrier and UL Listed certification, which simplifies compliance during audits and customer inspections. This combination helps ensure safe operation, proper protection clearances, and consistent adherence to national safety standards in industrial installations.
The HDSS designation reflects rugged construction and dependable protection, including an enhanced visible blade for safer isolation and a NEMA 1 enclosure designed for indoor environments. Compatibility with #6-250 kcmil conductors and three-pole four-wire wiring supports straightforward maintenance, rapid fault isolation, and safer servicing workflows.
Investing in the DH324NGKV yields lower maintenance costs due to durable construction, fewer nuisance trips, and easier fuse replacement with standard Class H fuses. The UL Listed and NEC barrier-compliant design also reduces compliance risk, often shortening approval cycles and minimizing downtime during upgrades or line resets.
