B-LINE KNA4C3DP21LV – Frequently Asked Questions

1) Is the Eaton B-Line Guardian DP21 KNA4C3DP21LV rated for washdown or outdoor enclosures?
The Guardian DP21 climate control unit, model KNA4C3DP21LV, carries a NEMA 4X degree of protection, which covers hose-directed water and corrosive environments such as washdown areas, food and beverage plants, and coastal outdoor sites. The housing is stainless steel with an ANSI 61 gray painted finish, so it holds that rating against corrosion rather than relying on paint alone. Match it to an enclosure with the same 4X rating; mounting a 4X unit on a lower-rated box does not raise the box.
2) How heavy is the Guardian DP21 enclosure climate unit, and can one person hang it?
It weighs 54 pounds. That is a two-person lift on a vertical panel, or a one-person job with a hoist or a temporary support bracket. The weight also matters for the enclosure itself: a 54 pound door-mounted load on a thin-gauge cabinet door can rack the door and break the gasket seal, which defeats the NEMA 4X rating. On lighter enclosures, mount it on the side panel or add door reinforcement.
3) Why choose a stainless steel climate control unit instead of a painted steel one?
Stainless steel is what makes a NEMA 4X claim hold up over time in chemical, saltwater, or daily washdown service. Painted carbon steel units carry lower ratings and will eventually rust through at cut edges and fastener penetrations. The Guardian DP21 unit uses a stainless steel body with an ANSI 61 gray painted finish over it, so you get corrosion resistance plus a color match to standard gray enclosures. In a dry indoor control room, that corrosion protection is cost you may not need.
4) What part number do I quote for the Eaton B-Line Guardian DP21 in NEMA 4X stainless?
Order it as KNA4C3DP21LV from Eaton's B-Line series. That single catalog number covers the Guardian DP21 climate control product in NEMA 4X, stainless steel, ANSI 61 gray painted. There are no separate finish or size options to specify under it.
5) Will the gray finish on this B-Line climate control unit match my existing electrical enclosures?
The finish is ANSI 61 gray painted, which is the standard gray used across most industrial control enclosures and switchgear, so it blends with a typical B-Line or comparable ANSI 61 cabinet lineup. Facilities standardizing a plant floor on one color can specify this unit without a repaint.
