What you're actually bolting into the panel
The ABB 1SAM580000R1008 is described as a Manual Motor Starter MS497-75 — a rotary-handle, panel-mount device combining disconnect, short-circuit protection, and thermal overload in one housing rather than separating the breaker from the contactor. It runs in ABB's MS-series protection family, so existing MS-series accessories — auxiliary contact blocks, shunt trips, undervoltage releases, rotary handle kits — fit the same mounting slots on the 1SAM580000R1008 without adapter plates. Specify the suffix explicitly when ordering so the thermal element matches the motor's full-load current.
Sourcing posture for the BOM line
The 1SAM580000R1008 is specified into the BOM against a 4–6 week lead, so it fits cleanly into a planned outage schedule but is not a same-week emergency replacement — keep one in the storeroom if the line cannot tolerate a month of risk on a single motor feeder. ABB has kept this manual motor starter in continuous use as a panel-builder staple, so the part is treated as an active line item and sourced to order against an RFQ rather than run through a broker channel. Drop the exact order code into the BOM line — ABB does not cross it to another suffix as an equivalent.
Setting the overload and the coordination check
Set the thermal dial on the front of the 1SAM580000R1008 to the motor's nameplate full-load current, not the wire ampacity — the heater inside the MS497-75 is sized for motor protection, and picking the wire rating instead will either nuisance-trip on a cold start or let a mechanically jammed rotor sit drawing locked-rotor current long enough to cook the windings. ABB's MS-series trip curves are published against the motor FLC setting, so the coordination study downstream of this device should reference the trip class stamped on the nameplate, not a generic inverse-time breaker curve.
Field-service notes when one trips and won't reset
If the 1SAM580000R1008 trips and refuses to reset, walk the motor first — check for a mechanically jammed load, a phase loss at the line side lugs, and a nameplate FLC that has drifted upward after a rewind. The MS497-75 thermal element is single-phasing sensitive, so a lost phase on a running motor will trip the device even when the running current looks acceptable on a clamp meter reading only two of the three legs. Verify the rotary handle is fully in the OFF position before re-latching — the family has a trip-free mechanism that will not let the contacts close if the handle is still sitting in the detent between OFF and ON, and the field tech's instinct to push harder is what bends the detent spring over time.
