Eaton DH325NGKV Heavy duty fusible safety switch - UL Listed

With a 400 A amperage rating and 240 V operation, the DH325NGKV provides robust feeder protection for high-load circuits. This capability helps prevent nuisance trips and arc-flash risks while preserving motor startup performance. For panel builders, it translates into a compact protection device footprint without compromising safety in main distribution applications. Three-pole, four-wire configuration with neutral simplifies wiring and phase balance across the installation. The neutral integration reduces wiring errors in control panels and supports clean fault isolation during maintenance, which shortens downtime and accelerates commissioning for complex machines in manufacturing environments. This configuration accommodates diverse control strategies and simplifies future upgrades. NEMA 1 enclosure with painted steel construction delivers indoor protection and durable service life in busy plant floors. This enclosure choice eases installation and future maintenance, since the exterior resists routine wear while keeping internal components shielded from dust and incidental impacts. The robust finish supports longer intervals between repainting and reduces cosmetic repairs in harsh factory environments. UL Listed and NEC 230.62 barrier compliance provide essential regulatory assurance for industrial facilities and system integrators. The combination of certification, effective safety barriers, and a rugged HDSS platform reduces compliance risk and helps pass audits during panel upgrades or new line builds. These features translate into lower total cost of ownership through fewer delays and streamlined field installations. HDSS features, including enhanced visible blade and a fuse provision for Class H devices, support quick visual checks and reliable protection against short circuits. The neutral and fusible configuration enable straightforward maintenance and seamless compatibility with standard control panels, enabling faster service turns and lower lifecycle costs. In practice, technicians report faster fault verification and safer, cleaner disconnects during routine maintenance.
