The ABB 1SBL161001R8101 is an electrical contactor in the Contactors and Starters line under Circuit Breakers, Fuses & Protection, with that order code as the part number. In a panel it sits in the same drawer as the rest of the motor-starter hardware — alongside short-circuit protection upstream and the overload relay it will command — so it gets specified against a coil voltage, a contact arrangement, and a current class before it ever lands on a BOM line.
Handling for the field swap
Coil-side wiring and aux-contact landings follow whatever the matching ABB block accepts, so the swap-out step is mechanical: de-energize, pull the coil spade, drop the contactor off the rail, and seat the replacement before re-landing the control wiring.
Sourcing posture
No lifecycle status, last-time-buy date, or official successor is carried against this order code in the record, so production state is open — the safe path is to quote the line against an RFQ rather than assume a current-factory ship date.
