Feature → Business Impact → Application: Enhanced visible blade improves status visibility during maintenance, reducing misoperation and speeding fault diagnosis, which translates to shorter repair times and lower downtime. This directly supports high-production environments where quick isolation is critical; use in motor control centers and outdoor equipment with confidence. Feature → 400 A amperage rating enables direct handling of large motor loads, delivering safer isolation and minimizing the need for additional interlocking or reconfigurations; critical for conveyors and pumps where reliability matters. Feature → NEMA 4 enclosure and painted steel construction provide moisture, dust, and washdown resistance, extending service life in harsh plants or outdoor facilities with lower maintenance costs over time. Feature → Cartridge fuse provision and fusible-without-neutral configuration simplify replacement and ensure consistent overcurrent protection, reducing inventory complexity and enabling faster maintenance swings. Feature → 240 V primary, with HP ratings up to 50/125/50 hp (3PH @ std fuse/time delay/250 Vdc), supports a wide range of medium- to high-power equipment, ensuring compatibility with existing motor names and control schemas. Feature → Two-pole, two-wire design reduces wiring complexity during installation and service, enabling quicker field wiring and safer operation in tight electrical rooms. Feature → Enhanced compatibility with multiple conductor sizes ((2) #1/0 – (2) 300 kcmil or (1) #1/0 – (1) 750 kcmil Cu/Al) supports diverse plant layouts and up-size strategies, improving long-term scalability. Feature → UL Listed certification and HDSS catalog notes reassure compliance teams and procurement, helping you meet internal standards and external audits with minimal risk. Application → Use in protection panels, motor feeders, and protection switches where rugged, reliable isolation is required; especially effective where outdoor exposure or washdown is a factor.

FAQs
The DH225FPKV is a two-pole, two-wire safety switch rated for 400 A with a 240 V nominal voltage. It uses cartridge fuses and a fusible-without-neutral configuration, suitable for 3-phase motor loads up to 50/125/50 hp (as specified). Ensure adequate space for the 57 in length, 27 in width, and 11 in height enclosure, and plan for a NEMA 4 environment. Use appropriate conductor sizes such as 2/0 to 300 kcmil copper or equivalent aluminum sizes as listed in the conductor sizing guidelines. This minimizes wiring errors and simplifies future upgrades.
The DH225FPKV provides a 400 A amperage rating with a 240 V voltage rating. Its HP protection range is specified as 50, 125, and 50 hp for 3-phase operation when using standard time-delay fuses and a 250 Vdc circuit as applicable. This enables protection for a broad class of industrial motors and aligns with common plant motor control configurations, reducing the need for multiple switch models.
Yes. The unit uses a NEMA 4 enclosure with painted steel construction, providing robust protection against moisture, dust, and water ingress. UL Listed certification further reinforces compliance with safety standards. This makes it appropriate for outdoor installations, washdown areas, and other demanding plant environments where reliable isolation is critical.
The DH225FPKV carries UL Listed certification and comes in a NEMA 4 enclosure, designed for rugged industrial service. The enhanced visible blade feature facilitates quick visual confirmation of switch status, improving safety during maintenance. Together, these features support regulatory compliance and safer operation in maintenance-intensive environments.
Cartridge fuse protection and a fusible-without-neutral design simplify fuse replacement and reduce spare parts complexity. The two-pole, two-wire configuration minimizes wiring time during installation and servicing. The combination of durable enclosure, simple maintenance, and clear status indication translates to shorter downtime, faster repairs, and lower total cost of ownership in mid- to large-scale industrial facilities.
