Where this class of part earns its keep
The 1SAM461000R1014: Accessories in this slot pair with ABB's MS / MO-series manual motor starters and the matching contactor frames to add auxiliary signalling, shunt trips, or undervoltage releases — the kind of piece you specify when the panel needs a tripped signal back to the PLC or a remote coil-drop command, not when you need a switching contactor itself.
Sourcing posture
No explicit lifecycle or production-status entry travels with this part number, so treat the official production line as unconfirmed rather than reading it as either active or obsolete — quote it against an RFQ, name the order code exactly as printed on the BOM (1SAM461000R1014), and let the response confirm channel and any last-time-buy constraints at the time of order.
