FAQs
DH368NGK is designed for three-pole, four-wire configurations with a neutral and a 600 V rating. It uses Class L fusing in a NEMA 1 painted steel enclosure, making wiring straightforward for indoor power distribution panels. When planning installation, ensure compatible lugs and conductor sizing (up to the specified NEC/UL guidelines) and provide adequate clearance for a 72 in length device to optimize maintenance access.
The device supports 1200 A, 600 V operations with fusible protection, configured as three-pole with four wires and a neutral. The fuse class is Class L, and the enclosure is designed for indoor use (NEMA 1). These specifications enable reliable fault isolation for large feeders while meeting common industrial standards and safety requirements.
Yes. With its 1200 A rating, 600 V capability, fusible with neutral configuration, and robust NEMA 1 enclosure, the DH368NGK is well-suited for large motor feeders and high-current distribution within manufacturing, processing, and heavy industrial settings. The UL Listed certification further supports safe operation and integration with existing switchgear and control panels.
The DH368NGK carries UL Listed certification and a NEMA 1 indoor enclosure rating, aligning with common regulatory and safety expectations for industrial protection devices. A one-year warranty from installation or 18 months from shipment provides lifecycle protection. These attributes simplify audits, improve procurement confidence, and support predictable maintenance planning.
The heavy-duty construction, UL Listed safety certification, and robust enclosure design contribute to reduced downtime and longer service intervals. Large, stable dimensions with a solid steel enclosure minimize field adjustments and wear. Combined with the warranty terms, this translates into lower total cost of ownership and clearer budgeting for upgrades or replacements in critical power distribution.
