200 A amperage rating with four-pole design enables high-load motor circuits to be protected with a compact form factor. The business impact is reduced fuse maintenance and safer switching sequences, minimizing downtime in machine lines and control panels. This is ideal for motor control centers and heavy machinery feeders in manufacturing plants. NEMA 12/NEMA 3R enclosure and painted galvanized steel enclosure provide weather and dust resistance, which translates into lower corrosion-related maintenance and longer service life. Field modification capability to meet NEMA 3R rainproof requirements adds installation flexibility in exposed locations. Fusible without neutral configuration and Class H fuse provisions simplify sourcing and field adaptation, reducing spare parts inventory while maintaining high fault isolation. 600 V ratings and #6-300 kcmil copper/aluminum conductor compatibility enable scalable solutions for diverse drive systems and power distribution schemes. UL Listed certification and four-wire, four-pole arrangement improve safety compliance and ease of integration with existing protective relays and control logic. A one-year warranty from installation (or eighteen months from shipment) provides financial protection against early failures and supports asset lifecycle planning. Installation considerations: 37.5 in depth, 11.5 in height, 19 in width, and a weight of 58 lb help with fit checks and mounting calculations in panel spaces, while the drain hole option supports field modifications in adverse climates.

FAQs
DH464FDK is designed for four-pole, four-wire configurations and fits standard industrial panel footprints that require a NEMA 12/3R enclosure. It supports field modifications to meet weatherproof requirements and aligns with common control relay schemes, easing retrofits and new installations alike while reducing wiring complexity.
The unit is rated for 200 A with a maximum of 600 V, featuring four-pole, four-wire configuration and fusible without neutral. It uses Class H fuses and is UL Listed, supporting copper and aluminum conductors from #6 to 300 kcmil. The enclosure is NEMA 12/NEMA 3R compatible, providing robust protection in diverse environments.
Yes. While standard installation is NEMA 12, the DH464FDK can be field modified to meet NEMA 3R rainproof requirements by opening a factory drain hole. This enables outdoor or damp-location service without compromising safety or performance, making it suitable for exposed plant areas.
The DH464FDK carries UL Listed certification, confirming adherence to stringent safety standards. Its NEMA 12/3R enclosure rating and four-pole, four-wire configuration support compliant protection for industrial panels, drive systems, and motor protection schemes within controlled industrial environments.
The 58 lb heavy-duty design reduces handling risk during maintenance, while the Class H fusible configuration minimizes downtime during fuse changes. The product warranty—one year from installation or eighteen months from shipment—offers asset protection and predictable lifecycle budgeting, contributing to lower total cost of ownership in chronic maintenance environments.
