It uses cartridge fuses and is configured fusible without neutral, designed for two-wire circuits in motor and control applications, ensuring proper overload protection and clear fault isolation.
Yes, the DH225FDKV is UL Listed and complies with NEC requirements, including NEC 230.62 barrier guidelines. The enclosure’s NEMA 12/3R rating further supports compliance for a wide range of indoor and outdoor industrial installations, providing safe operation and traceable certification for installers and end users.
By delivering robust protection with a cartridge fuse design and a durable galvanized enclosure, the DH225FDKV reduces unplanned outages and maintenance frequency. Its UL and NEC compliance minimizes regulatory risk, while its straightforward wiring and reliable motor protection lower installation and downtime costs across mid-size industrial assets.
Plan for a two-wire, two-pole hookup with cartridge fuses and a 240V supply. Ensure the enclosure is mounted in a compliant space (indoor or outdoor) and that the surrounding panel allows for 65.5 in depth, 10.5 in height, and 25.5 in width. Verify motor load matches the HP rating and use appropriate fuse types and time-delay characteristics.
