FAQs
DH223FDKW is a two-pole, fusible safety switch rated for 100 A and 240 V in indoor NEMA 1 enclosures. It supports 1- and 3-phase motor loads and uses Class H fuses without a neutral. For retrofit projects, verify panel space, wiring method, and available fuse blocks to ensure a straightforward drop-in replacement with proper torque settings on terminal connections.
Key specs include a 100 A amperage rating, 240 V nominal voltage with a 600 V maximum, and HP ratings up to 7.5–30 hp depending on configuration and phase. It is designed for heavy-duty motor protection, with two-pole operation and a fusible design to interrupt fault current quickly, supporting reliable shutdown in fault conditions.
The DH223FDKW uses a NEMA 1 enclosed painted steel enclosure intended for indoor dry locations. While it provides robust protection from dust and incidental contact, it is not rated for outdoor or wet environments. Use in dry industrial spaces and control rooms where enclosure integrity can be maintained.
The unit is UL Listed, with a NEMA 1 enclosure and Class H fuse provision. Warranty terms follow Eaton’s policy: one year from installation or eighteen months from shipment, whichever comes first. This combination supports regulatory compliance and predictable long-term maintenance planning.
The window and visible blade allow quick, non-contact status checks of the switch's operating blade without full disassembly. This reduces maintenance time, enhances safety during routine inspections, and helps confirm proper isolation before servicing industrial equipment, improving overall maintenance efficiency.
