Eaton DH323NGK-CSA Heavy duty fusible safety switch - UL Listed CSA Certified

With a 100 A amperage rating, 240 V operation, and a three-pole, four-wire configuration, the DH323NGK-CSA provides robust protection for medium-sized motors. This combination reduces nuisance faults and inrush-related stress, translating into higher line availability and lower maintenance costs. The painted steel, NEMA 1 enclosure resists indoor dust and minor impacts, enabling reliable service in typical factory environments and simplifying mounting alongside existing gear. The Class H fuse provision and fusible-with-neutral configuration offer selective protection and clean fault interruption, minimizing arc energy and facilitating coordination with upstream protection schemes. Field wiring remains straightforward: Cu or Al conductors from #14 to #1/0 AWG fit comfortably, reducing inventory complexity. Compatibility with standard 3-phase feeders supports faster panel upgrades and easier retrofits. The HP rating—7.5, 15/15, and 30/20 hp (1,3PH @Std/TD/250 Vdc)—covers a broad spectrum of motor loads, enhancing flexibility across lines. UL Listing and CSA Certification, along with NEC barrier compliance, align with rigorous safety and QA requirements, while the rugged, indoor-oriented design minimizes downtime and service calls. These design choices collectively reduce total cost of ownership by improving reliability, simplifying procurement, and speeding installation in real-world industrial environments.
