ABB SR Series XT1 Blank Filler Plate Mounting Kit
The ABB SR Series Blank Filler Plate is a mounting kit accessory engineered for use with ABB's Tmax XT1 molded case circuit breaker platform. This family is available across three SR Series models — SR1XBF, SR2XBF, and SR5XBF — each sized to match a corresponding XT1 mounting frame configuration. The filler plate occupies unused mounting positions within a breaker enclosure or mounting frame, helping panel builders and electricians maintain a finished, organized appearance when a full complement of breakers is not installed. Supplied as a single-unit accessory, each model in the SR1XBF, SR2XBF, and SR5XBF range complements other SR Series mounting kit components used alongside ABB XT1 breakers in commercial and industrial distribution equipment.
Key Features
- Blank Filler Function: Covers unused breaker mounting positions within the enclosure, keeping the interior of the equipment enclosed and tidy when fewer than the maximum number of breakers are installed.
- ABB XT1 / SR Series Compatibility: Purpose-built as part of the SR Series mounting kit accessories for ABB Tmax XT1 molded case circuit breakers, available in the SR1XBF, SR2XBF, and SR5XBF models to support consistent fit and finish across the mounting system.
- Simple Installation: Designed as a drop-in accessory for the XT1 mounting kit, allowing panel builders to quickly fill open positions without modifying the enclosure or mounting frame.
- Single-Unit Packaging: Each model ships as 1 each, making it easy to order the exact quantity of filler plates needed for a given installation or retrofit.
- Consistent System Fit: Matches the mounting kit hardware used elsewhere in the XT1 SR Series lineup, supporting a uniform look and feel across the finished panel or enclosure regardless of which model in the range is selected.
- Panel Organization: Helps electricians and panel builders present a clean, professional finished enclosure on jobs where breaker counts may grow over time.

ABB SR5XBF – Frequently Asked Questions
1) What does the ABB SR Series blank filler plate actually do in an XT1 panel?
It covers an unused breaker mounting position inside an enclosure or mounting frame built around ABB Tmax XT1 molded case breakers. Where fewer than the maximum number of breakers are installed, the filler plate closes off the open position so the interior stays enclosed and the front presents a finished face. It carries no breaker function of its own, it is purely a cover accessory in the SR Series mounting kit lineup.
2) Which ABB filler plate model do I order, SR1XBF, SR2XBF or SR5XBF?
Three models are offered: SR1XBF, SR2XBF and SR5XBF. They are all blank filler plates for the XT1 SR Series mounting kit, and the model you need is the one matching the mounting kit already used in that enclosure. Match the model to the SR kit designation on your existing hardware rather than to the breaker frame alone.
3) Will an ABB XT1 blank filler plate fit a panel that uses a different breaker brand?
No. These filler plates are built for ABB's SR Series mounting kits used with Tmax XT1 molded case breakers, and the fit is specific to that mounting system. For a different platform you need that manufacturer's own filler, for example the Eaton GB/GHB/GHBS single pole panel mount filler plate for Eaton panels of that series.
4) Do I have to modify the enclosure or drill anything to install this filler plate?
No cutting or drilling. It is a drop-in accessory for the XT1 mounting kit, so it seats into the open position in the existing frame without altering the enclosure. That matters on a retrofit where the panel is already built out and you only want to close off positions being held for future breakers.
5) I'm leaving spare breaker positions for future expansion, is a filler plate the right way to close them off?
Yes, that is exactly the case these are made for. Panel builders and electricians use them on jobs where breaker counts grow over time: the position stays covered and the enclosure stays closed until a breaker goes in, then the plate comes out. Since it drops into the existing XT1 mounting frame, adding the breaker later doesn't mean reworking the panel.
6) Is the ABB SR blank filler plate a breaker or does it carry any current?
Neither. It is a blank cover plate only, classed as a filler plate accessory. There are no line or load terminals and nothing is energized by it. Its job is to occupy an unused mounting position within the XT1 breaker enclosure so the equipment interior stays enclosed.
7) How many filler plates come in a pack from ABB?
One. Each SR Series blank filler plate is supplied as a single unit, so order one per open mounting position you need to cover. On a panel with four empty spaces, that is four pieces.
