Siemens SBS2020F

✓ Authorized Siemens distributor

✓ Hard-to-find and manufacturer-specific equipment

✓ Since 1972

Installing a Siemens SBS2020F means dropping a retired frame back into a live board. Holdings in that family run through Bud Ferguson's Industrial Control & Supply Inc., stocked since 1972. Switchboard owners nationwide order the Siemens SBS2020F from one warehouse. Fifty-plus years of stocking is what produces depth in lines the factory has dropped, backed by authorized distribution.

Performance Behind the Siemens SBS2020F

Bridging molded case and power breaker design is what the Siemens SBS2020F does inside a switchboard. Breaking capacity, withstand rating, and short-time performance all come out of that combination. Insulation built into the housing is what the encased description refers to. True RMS sensing in the trip unit beats an averaging measurement on distorted waveforms. Adjustment across ampere values happens at the plug rather than the frame. Stored energy closing gives the mechanism its two-step operation.

Rated Amps, Pole Count, and Voltage

Decoding the designation gives type SBS, a 2000 amp frame at full trip, and fixed mounting on the Siemens SBS2020F. Scale like that puts it among the heavier of our industrial circuit breakers. Service is three-phase across three poles at up to 600 volts. Suffix letters mark the unit as fixed rather than draw-out. Plug values on that frame run 1200, 1600, and 2000. Electronic trip units and neutral sensors are supplied to suit. Cradle hardware does not form part of a fixed-mount order. Weight and section dimensions match the original drawings.

Mount Style and Whether a Swap Is Possible

Exchanging a Siemens SBS2020F for a draw-out version needs a cradle the board may lack. Newer switchgear runs Siemens WL breakers on a different mounting standard. Connections to the bus and cubicle depth both differ between the two designs. Lower trip ratings on the same size point to Siemens SBH2008F instead. Figures under 1200 fall outside what the SBS letter covers. Mistaking one designation for another means a unit that will not bolt in. Confirming both before ordering saves a return.

Put a 2000 Amp Frame Back into Service

Sections come back online only once the correct Siemens SBS2020F arrives. Markings on the label give type, frame size, trip rating, and mount style. Passing those to our electrical equipment supplier starts the search. Overhauled frames arrive with an inspection and test record. Ancillary items can travel with the breaker or ship separately. Crating leaves one warehouse bound for any point in the country. Specify a fixed mount when you request a quote, and the SBS frame drops back into service.
