The 100 A amperage rating gives a robust disconnect for medium to large motor loads, enabling rapid fault isolation and safer startup sequences. This translates to fewer unplanned shutdowns and lower maintenance costs in busy production lines. It is well-suited for motor control centers and industrial feeders where predictable performance matters. The NEMA 1 painted steel enclosure provides indoor protection against dust and incidental intrusion, supporting reliable service in controlled plant environments. NEC 230.62 compliant barriers further enhance maintenance safety and regulatory alignment for indoor switchgear installations. The fuse configuration offers Class H protection with a neutral, delivering selective protection and quicker fuse replacements, reducing downtime during maintenance windows. With a three-pole, four-wire design, it fits standard industrial layouts and simplifies wiring schemes for technicians. The 600 V rating and up to 75 hp performance (1/3PH @480, 600 V) cover a broad range of drive and motor applications, while UL Listed certification reinforces quality expectations. Overall, the DH363NGK provides a balanced combination of protection, ease of installation, and long-term reliability for modern industrial control systems.

FAQs
Yes. The DH363NGK supports 480V three-phase operation as part of its 600V class rating, with a horsepower range up to 75 hp (1/3 PH at 480V). When deploying in 480V systems, ensure proper conductor sizing and fuse selection per Class H specifications to maintain safe, code-compliant isolation in motor control centers.
Key specs include a 100 A amperage rating, 600 V maximum voltage, three-pole configuration, four conductors, and a fusible with neutral arrangement using Class H fuses. The enclosure is NEMA 1, the unit is UL Listed, and its HP rating reaches up to 75 hp for certain 480/600 V configurations. It is designed for 600 V systems and Cu/Al conductors from #14 through #1/0.
The DH363NGK uses a NEMA 1 painted steel enclosure, which is intended for indoor use in non-hazardous environments. It is not rated for hazardous or demanding outdoor locations. For harsher environments, consider enclosures with higher protection ratings and consult local codes for appropriate equipment selection.
Yes. The DH363NGK is designed with NEC 230.62 barrier compliance in mind, providing a safe isolation path that facilitates compliant servicing and reduced risk during maintenance. This barrier compatibility helps align installation practices with critical electrical safety standards in industrial facilities.
The product is covered under Eaton's standard warranty policy, which generally provides one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, follow standard inspection intervals for disconnect switches, verify fuse integrity, and ensure the 600 V circuits are de-energized before servicing. Regular checks reduce unplanned downtime and extend service life.
