Construction & Configuration
These ABB ReliaGear Pro-Stock enclosures provide the box portion of a compatible unassembled lighting panelboard system. The enclosure is selected according to the height requirement of the panelboard interior.
Each model in this product group is 20 inches wide and supplied with blank endwalls.
The NEMA 3R configuration is intended to provide an enclosure option for compatible installations requiring protection appropriate to that enclosure classification.
Selecting the Correct Enclosure
43.5" Height
Choose AB433 when the selected compatible ReliaGear panelboard interior requires a 43.5-inch-high enclosure.
49.5" Height
Choose AB493 when the selected compatible ReliaGear panelboard interior requires a 49.5-inch-high enclosure.
76.5" Height
Choose AB763 when the selected compatible ReliaGear panelboard interior requires a 76.5-inch-high enclosure.
ReliaGear Pro-Stock System
Unassembled Panelboard System
ReliaGear Pro-Stock lighting panelboards use an unassembled approach that allows the interior, enclosure, front, main, and applicable breaker components to be selected for the installation.
Match the Box to the Interior
ABB's selection process calls for identifying the required box/front height from the selected interior and then choosing an enclosure with the corresponding height.
Enclosure Selection
The correct enclosure should be selected based on the compatible panelboard interior rather than by enclosure dimensions alone.
ABB's Pro-Stock selection process begins with selecting the appropriate interior based on electrical requirements. The interior selection determines the required box/front height, which is then used to select the enclosure.
Confirm the exact interior catalog number, required enclosure height, NEMA rating, and associated components before ordering.
