FAQs
When installing the DG221NGB, ensure a two-pole, three-wire configuration with fusible neutral as specified. Verify the NEMA 1 painted steel enclosure fits the panel opening and that the 240V supply and 30A load align with the Class H fuse requirements. Follow lockout/tagout procedures and consult the NEC barrier guidelines during mounting to maintain safe clearance and isolation.
Key specifications include a 30A amperage rating, 240V voltage rating, two-pole configuration, fusible with neutral, and Class H fuses. The unit uses a three-wire connection and is designed for general duty safety switching. It is UL Listed and suited for low-voltage control circuits in industrial environments, with a NEMA 1 painted steel enclosure.
Yes. The DG221NGB is designed with NEC 230.62 barrier compliance in mind, providing a safe and code-conforming isolation barrier within the enclosure. This helps installers meet regulatory expectations during commissioning and reduces the risk of non-compliance findings during inspections.
The DG221NGB carries Eaton’s standard warranty: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. This warranty covers manufacturing defects and sets a clear service expectation for OEMs and end users, supporting maintenance planning and lifecycle budgeting.
Maximum horsepower ratings apply only when dual-element fuses are used. The catalog notes indicate a grounded B phase rating for 3-phase configurations, and the unit is UL listed for safe operation. Engineers should verify hp and motor type per the dual-element fuse guidance to ensure reliable protection in 3-phase drives and motor circuits.
