Square D 9991DPG1 – Frequently Asked Questions

1) Will the Square D 9991DPG enclosure fit my 8910DP definite purpose contactor?
The 9991DPG enclosure is built specifically for Square D 8910DP and 8910DPA definite purpose contactors rated 20A through 40A, in 2 pole and 3 pole configurations. It comes in two sizes, 9991DPG1 (Size 1) and 9991DPG2 (Size 2), so match the size to the frame of the contactor you are mounting. It houses the contactor only, it does not include one.
2) Can I mount a 9991DPG contactor enclosure outdoors or in a washdown area?
No. It is a NEMA Type 1 enclosure, which is general purpose indoor protection against incidental contact and falling dirt only. It offers no rating against rain, sprayed water, or washdown, so a rooftop condenser, an exterior wall, or a wet process area needs a NEMA 3R, 4, or 4X housing instead. Indoor mechanical rooms, control rooms, and panel walls are where this one belongs.
3) Does the Square D 9991DPG come with the contactor, or do I order that separately?
The enclosure ships as a housing. The 8910DP or 8910DPA contactor is a separate order, and so is any pilot device, wiring, or conduit fitting the installation needs. Plan on specifying the contactor first, by pole count and amp rating within the 20A to 40A range, then match the enclosure size.
4) What is the difference between the Size 1 and Size 2 Square D 9991DPG enclosures?
Both are sheet steel NEMA 1 housings for 8910DP/DPA contactors; the difference is the interior space. Order 9991DPG1 for the smaller contactor frame and 9991DPG2 where the larger 2 or 3 pole unit, or added wiring room, requires it. Identify the contactor you are enclosing first, then pick the matching size, since the enclosure is sold by size and not by contactor amp rating.
5) Is the Square D 9991DPG enclosure CSA certified for a commercial control panel job?
CSA certified, and that is the listing it carries. For an inspector on an indoor commercial or industrial installation, the relevant pair of facts is the CSA certification plus the NEMA Type 1 general purpose rating. If your spec calls for a specific UL enclosure type or a rating above Type 1, this is not the housing for that opening.
6) I am replacing a rooftop unit contactor. Do I need a 9991DPG enclosure too?
Only if the contactor is mounted somewhere it needs its own indoor housing. Contactors installed inside an existing HVAC unit cabinet or an existing panel already have enclosure protection and do not need this. The 9991DPG is for 8910DP/DPA contactors mounted standalone in an indoor location, and since it is NEMA Type 1 it cannot be used on the roof or on an exterior wall.
7) What material and finish is the 8910DP series contactor enclosure, and will it hold up in a mechanical room?
Sheet steel with a painted gray finish. That gives an impact resistant housing for the contactor and a clean look in a control panel lineup, and it is appropriate for dry indoor mechanical and electrical rooms. Steel is not the right choice for corrosive or wet locations, where a non metallic or stainless enclosure is used instead.
