ABB ReliaGear Pro-Stock 42-Circuit Panelboard, Copper Bus, 240V 3-Phase

The ABB ReliaGear Pro-Stock Panelboard is a 42-circuit, 240V 3-Phase distribution panel built on a symmetrical, reversible-interior design that supports either top or bottom feed without pre-specifying orientation. Copper bus construction delivers dependable current-carrying capacity for commercial and industrial distribution, and the panel is available with main breaker or main lugs so the same enclosure can serve service-entrance or feeder distribution applications. As part of the ReliaGear Pro-Stock modular kit program, this configuration is drawn from an inventory of over 1,500 available panel designs, giving distributors and contractors fast access to the exact panel configuration a job requires.

Key Features

  • Reversible Interior: Symmetrical design supports top or bottom feed without pre-specifying orientation, simplifying stocking and installation.
  • Circuit Capacity: 42 circuits (feeders) for flexible branch circuit distribution in commercial and industrial panels.
  • Voltage Rating: 240V, 3-Phase electrical service suitable for standard commercial distribution systems.
  • Durable Construction: Copper bus construction for reliable current-carrying capacity and long-term performance.
  • Main Configuration: Available with main breaker or main lugs per ReliaGear Pro-Stock modular kit options, covering both service-entrance and sub-feed applications.
  • Main Bus Ratings: Main bus ratings of 250A and 400A main breaker; 225A, 400A and 600A main lug configurations are available across the ReliaGear Pro-Stock line for this panel family.
  • Mounting: Designed for standard panelboard mounting per ReliaGear Pro-Stock enclosure specifications.
  • Stocked Availability: One of over 1,500 modular panel designs available from inventory for immediate availability, reducing project lead times.

ABB AQU3302RCXAXT1B4 – Frequently Asked Questions

1) Can the ABB ReliaGear Pro-Stock panelboard be fed from the top or does the feed have to come in at the bottom?
Either. The ReliaGear Pro-Stock interior is symmetrical and reversible, so the same panel takes a top feed or a bottom feed without you specifying orientation when you order. That matters on a retrofit where the existing conduit comes in from the slab, and it means one panel on the shelf covers both conditions.
2) Is the ABB ReliaGear Pro-Stock 42-circuit panel a main breaker or main lug panel?
Both configurations exist in the ReliaGear Pro-Stock kit program for this panel family, and the same enclosure serves either one. Main breaker is what you want at the service entrance where overcurrent protection has to sit in the panel; main lugs is the feeder or sub-panel arrangement where the upstream device already provides that protection. Decide which role the panel plays in the distribution before you pick.
3) What main bus amperages does the ABB ReliaGear Pro-Stock 240V panelboard come in?
Across this panel family the main bus ratings run 250A and 400A on main breaker builds, and 225A, 400A and 600A on main lug builds. The ordering options break out as 225A, and a 400A/600A group covering AQU3424RCXAXT1B4 at 400A and AQU3426RCXAXT1B4 at 600A. Size the bus to the calculated load and the upstream feeder, not to the circuit count.
4) Will a 240V 3-phase panelboard work on my 208Y/120V service?
Read the nameplate rating before you commit. The ReliaGear Pro-Stock configuration here is rated 240V, 3-phase. That is the voltage class the panel is built for, and a 240V 3-phase panel is normally applied on a 240V delta or comparable commercial 3-phase system. If your service is a different voltage class, order the panel built for that system rather than derating this one.
5) Is the bus copper or aluminum on the ABB ReliaGear Pro-Stock panelboard?
Copper. That is worth knowing on a spec job, because a lot of drawings call out copper bus explicitly and an aluminum-bus panel gets rejected on submittal. Copper also affects your termination practice at the lugs, so match your conductor terminations to what the lug is listed for.
6) How many branch circuits can I land in the ABB ReliaGear Pro-Stock panel?
42 circuits. That is the practical ceiling for branch distribution in the panel, so count your single-pole, two-pole and three-pole loads in pole positions before ordering. Three-phase loads eat three positions each, which fills a 42-circuit interior faster than a panel schedule with mostly lighting and receptacle circuits.
7) What is the difference between the AQU3302 and the AQU3422 ReliaGear panel?
Both are 225A builds in the ReliaGear Pro-Stock family, ordered as AQU3302RCXAXT1B4 and AQU3422RCXAXT1B4. They are separate stocked kit configurations at the same amperage, so when a drawing or an existing panel schedule names one of them, order that exact model number rather than treating the two as interchangeable.
8) Can I use this ABB panelboard to replace an existing panel in a renovation?
It is built for that. Typical applications include modular panel replacement and upgrades along with new construction and renovation. The reversible interior helps on a swap-out, since you do not have to match the original feed direction. What you do have to match is the voltage class, the phase configuration and the main bus rating against the existing feeder and overcurrent device.
9) Is ReliaGear Pro-Stock a stocked panel or a built-to-order panelboard?
Pro-Stock is the stocked modular kit program, drawn from an inventory of over 1,500 panel designs rather than engineered from scratch per job. For a contractor chasing a schedule or a distributor filling a counter order, that is the difference between a catalog configuration and an assemble-to-order panel that has to go through the factory queue.
