Sourcing and lead time
The 1SVR450332R0100: Estimated lead time sits at 4 to 6 weeks. That is a typical factory-build window for a current-production ABB control component — not a stocked shelf item, but a predictable order cycle. For a mill planner or MRO buyer, that means the part needs to be on the order sheet before the line-down window opens, not after.
What the 2x1c/o means on a motor load monitor
Two independent changeover contacts give you separate signalling paths — one can trigger an alarm lamp in the control room while the other drops out the motor contactor. That is a common arrangement on a pulp machine or a pump station where you want a warning before a hard trip. The CM-LWN series is a DIN-rail mount device, so it clips into the same panel as the motor starter and the PLC input card.
