FAQs
The DH361FDKJ is a three-pole, fusible-without-neutral switch designed to fit typical three-wire panels. It supports #14-2 AWG copper or aluminum conductors and is sized for a 20 in depth enclosure footprint with a NEMA 12/3R rating. Mounting should follow OEM guidelines, ensuring proper clearances and barrier separation per NEC requirements. Use the provided Class J fuses and verify compatibility with your panel layout and wiring harnesses for straightforward, code-compliant installation.
Key specs include a 30 A amperage rating, 600 V voltage rating, and a three-pole, three-wire configuration. The device is designed for three-phase motor circuits, delivering safe isolation and fuse-protected power paths. With a HP rating range of 7.5 to 20 hp (1/3 HP at 480 V) and NEMA 12/3R enclosure, it is well-suited to medium-size industrial loads while maintaining reliable protection during overloads and fault events.
Yes. The DH361FDKJ is purpose-built for AC three-phase motor circuits at 480–600 V, supporting up to 30 A and 7.5–20 hp depending on configuration. Its fusible design and NEMA 12/3R enclosure make it particularly suitable for conveyors, pumps, and similar equipment in demanding factory environments. For DC applications, this device is not specified and should not be used.
This switch is UL Listed and NEC 230.62 barrier compliant, with a NEMA 12/3R enclosure suitable for protected indoor use. These certifications help ensure safe operation, regulatory alignment, and correct barrier protection in industrial panels. Always verify site-specific codes and add-ons (like local inspection requirements) when planning installation in your facility.
Warranty is defined as Eaton Selling Policy 25-000, offering one year from installation or 18 months from shipment, whichever occurs first. Regular maintenance primarily involves fuse replacement and enclosure inspections, which minimizes downtime during fault isolation. By reducing unplanned outages and simplifying fuse-based protection, this switch supports lower maintenance costs and improved equipment uptime over its service life.
