Abb sr2xbf Next Superbox Two XT1 Mounting Rail

Product Description

The ABB sr2xbf is a mounting rail assembly designed for use with neXT SuperBox panelboard systems accommodating two XT1 breakers. This component provides the structural support rail, spacer blank, and filler elements needed to properly seat and secure XT1-series molded case circuit breakers within a neXT SuperBox enclosure. Electrical contractors and panel assemblers install this part during new panel builds or when reconfiguring breaker positions within an existing neXT SuperBox assembly. It ensures correct breaker spacing, mechanical alignment, and dead-front filler coverage in multi-breaker configurations.

This mounting rail is suited for commercial and industrial electrical distribution applications where neXT SuperBox panelboards are specified. It is used in new construction and retrofit panel work where XT1-series breakers are being installed or repositioned. Electricians working on low-voltage distribution panels will encounter this component when expanding or servicing neXT SuperBox assemblies that require dual XT1 breaker positions.

Key Features

• Combines mounting rail, spacer blank, and filler in a single assembly for complete two-breaker bay installation
• Designed to accept two XT1-series molded case circuit breakers in neXT SuperBox panelboards
• Provides proper mechanical spacing and alignment for reliable breaker seating
• Filler panel covers unused or adjacent openings to maintain dead-front safety compliance
• OEM-matched fit eliminates field fabrication of spacer and filler components

Compatibility

Designed for use with ABB neXT SuperBox panelboard systems requiring two-position XT1-series molded case circuit breaker mounting configurations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and the panelboard manufacturer guidelines. De-energize the panel and verify the absence of voltage before removing or installing any mounting hardware or breakers. Confirm that the rail and filler assembly is fully seated and mechanically secured before reinstalling the dead-front cover. Do not modify or cut the mounting rail to fit non-standard configurations.
