Sorry I can see where the problem is - we had old stock of 1-1611-300390 with Black covers which we have been converting locally to Blue Covers – This part is without auxiliary switch – I cannot see a part number in SAP for an equivalent, but we could accept 1-1611-345769 C220/600 24FV-V1 or 1-1611-224329 C220/600 24FV-VG1 Contactor NO (BLUE) as an alternative – Can you quote us price and lead time for 50 pcs?
