FAQs
DH223NGK is designed for indoor panels with a NEMA 1 enclosure and a two-pole, three-wire layout including a neutral. It fits standard mounting footprints and supports standard time-delay fuses. When planning installation, verify 240 V supply, ensure proper clearance for safe operation, and confirm compliance with NEC 230.62 barrier requirements to maintain safeguarding clearances.
HP ratings vary by configuration: 7.5 hp, 15 hp, and 30 hp options are available across 1- and 3-phase setups with standard fuse or time-delay fuses at 250 Vdc. This means you select the appropriate HP rating based on motor torque and startup behavior, while maintaining 240 V operation and 100 A protection.
Yes. The unit utilizes a NEMA 1 painted steel enclosure suitable for indoors, and it carries UL Listed certification for electrical safety. NEC 230.62 compliant barriers further ensure safe separation of live parts, supporting compliance in regulated facilities and audits.
The fusible with neutral design enables straightforward fuse replacement without disturbing control wiring. The Class H fuse provision supports reliable fault isolation, reducing nuisance trips. The UL listing and NEC barrier compliance simplify inspections, while the compact footprint eases preventative maintenance within crowded panels.
Plan for standard time-delay or fast-acting fuses compatible with Class H provisions and 250 Vdc operation. Ensure availability of a spare neutral fuse, verify the 240 V supply, and confirm that the panel supports 3-wire, two-pole configurations. The unit’s NEMA 1 enclosure and painted steel construction support straightforward mounting and long service life in indoor environments.
