Abb rnsb12b8445a Power Panelboard 1200A 600V 32-space

Product Description

The ABB rnsb12b8445a is a ReliaGear neXT SuperBox power panelboard rated for 1200 amps and 600 volts, designed for heavy-duty commercial and industrial power distribution. It ships with a main breaker configuration and delivers a 200 kA interrupt rating, making it suitable for applications where high available fault current is a design factor. The enclosure is NEMA 1 rated and mounts surface-style. Licensed electricians and electrical contractors are the primary installers of this equipment. The copper bus construction and 3-pole configuration support three-phase service feeds common in commercial and light industrial facilities.

This panelboard is applied in commercial buildings, industrial facilities, and similar occupancies requiring a large-capacity distribution point. The bottom-feed entry suits installations where conduit risers enter from below, a common layout in multi-story commercial construction and switchgear rooms. With 32 branch-circuit spaces, it accommodates substantial circuit density in a single enclosure. The surface mounting style simplifies installation against a wall or structural member without the need for a recessed pocket.

Key Features

• 1200 A continuous amperage rating supports high-load distribution systems
• 600 V voltage rating suitable for three-phase commercial and industrial service
• 200 kA interrupt rating handles high available fault current environments
• 32 circuit spaces provide dense branch-circuit capacity in a single enclosure
• Copper bus material for reliable conductivity and long-term durability
• Bottom-feed entry and surface mounting for straightforward conduit and structural integration
• NEMA 1 enclosure for indoor dry-location installations

Compatibility

Designed as an OEM-specification power panelboard for commercial and industrial three-phase distribution applications requiring 1200 A main breaker service at 600 V.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. The upstream service must be de-energized and locked out following LOTO procedures before any wiring connections are made. Verify that available fault current at the installation point does not exceed the 200 kA interrupt rating prior to energizing. The enclosure is rated NEMA 1 for indoor dry locations only and must not be installed in wet or damp environments.
