What this part is
The 1SBL141501R8100: Brand on the record is abb, with the title naming ASEA BROWN BOVERI as the originating house — a buyer cross-checking the nameplate against the PO line gets a clean ABB trace.
Sourcing reality and cross-reference
The 1SBL141501R8100 ships against an RFQ rather than a shelf-pull — independent traders and MRO storerooms should treat it as specified-into-the-BOM rather than walk-available via RFQ confirmation. No official successor or phase-out notice is on file for this order code, so lifecycle posture stays at quoted-to-order with no last-time-buy date to anchor.
Where it sits in the panel
Electrical Contactors in this ABB line are the muscle switches downstream of the circuit breaker and the overload — coil is energized by the control circuit, the power contacts carry the motor or heater load, and any auxiliaries piggy-back on the same frame.
