FAQs
Install the two-pole, two-wire DH221FDKW in a compatible panel with a NEMA12/3R-rated enclosure. Ensure sufficient clearance for the window and accessible blade, and wire the unit to provide fusible protection without neutral. The 9.89 in depth and 7.75 in width fit standard footprint panels, while the 240 V supply aligns with common industrial controls.
The device is rated for 30A and 240V operation, with a voltage maximum of 600V. It supports 1.5 HP (and up to 5 HP at 1PH 240V/250VDC). This makes it suitable for motor control and other heavy-load equipment in industrial settings.
Yes. The switch uses Class H fuse provision and is designed as fusible without neutral, simplifying wiring and improving fault isolation. This configuration helps maintain system safety while reducing stock complexity for replacement fuses.
Heavy commercial and industrial environments with demanding protection needs benefit most. Applications include motor control panels, equipment disconnects, conveyors, and processing lines where robust enclosure protection, visible blade access, and UL Listed safety are priority requirements.
The product carries UL Listed certification and Eaton’s HDSS designation, with a warranty policy of one year from installation or 18 months from shipment, whichever occurs first. This supports long-term reliability, service planning, and regulatory compliance in maintenance cycles.
