Siemens SBH2008F

✓ Authorized Siemens distributor

✓ Hard-to-find and manufacturer-specific equipment

✓ Since 1972

Requesting a Siemens SBH2008F usually starts with a puzzle about frame size. Inventories of that type have run through Bud Ferguson's Industrial Control & Supply Inc. since 1972. Consulting engineers and end users alike order the Siemens SBH2008F for delivery to all fifty states. Breadth of stock in discontinued Siemens families comes from over half a century of trading, backed by authorized distribution.

Headroom and Protection in the Siemens SBH2008F

Room to grow is part of what the Siemens SBH2008F offers, since 800 amps of trip runs on a 2000 frame. Short-time resistance at the section follows that larger body rather than the setting. Selective coordination gets easier when a big housing can hold a fault longer. Raising the trip later needs a rating plug, not a new breaker. Letters in that family rank interrupting capability, and SBH marks the upper end. Two-step stored energy closing comes as standard across the line.

Encoded in the Part Number

Splitting the designation gives type SBH, a 2000 frame, an 800 amp trip, and fixed mounting on the Siemens SBH2008F. Placement in the catalog puts it among our industrial circuit breakers. Six hundred volts is the ceiling, carried on three poles. Maximum tripping lands at 800 amps despite the larger body. Final letter records fixed mounting rather than draw-out. Upward adjustment reaches the full 2000 through the plug. Neutral sensors and trip electronics are ordered to match the shell. Dimensions of the section follow that 2000 rating rather than the setting.

Oversized Frames and Lower Trip Ratings

Oversizing the frame on a Siemens SBH2008F is deliberate rather than an ordering mistake. Running the same size at its full rating gives Siemens SBS2020F instead. Withstand at the section holds up whichever value the plug sets. Later designs move that duty onto Siemens WL breakers. Downsizing would cut the short-time capability a lineup relies on. Dropping to a molded case unit at 800 amps loses that headroom entirely. Sticking with the type letter preserves the original design intent.

Stay with the Type Your Board Needs

Rebuilding a section around a substitute costs more than sourcing a Siemens SBH2008F. Everything needed is on the cover, from the SBH letter through to the mounting. Handing those to our electrical equipment supplier narrows it immediately. Reworked units ship only after inspection and testing. Add-on items can accompany the breaker or follow separately. Transport leaves one warehouse for switchboards nationwide. To stay with the type that board needs, request a quote on the SBH frame it was built around.
