The 10 A AC-12 rating is the maximum continuous resistive load the contacts can carry. For inductive loads like small relays or contactor coils, derate per the AC-15 or DC-13 curves — the 24 V DC rating of 10 A is for resistive; at 110 V DC the rating drops to 1 A, and at 220 V DC to 0.27 A. The 6 kV surge voltage resistance means the contactor withstands typical switching transients without breakdown, important for panels near motor starters or VFDs. The shock resistance of 10g for 5 ms and 5g for 10 ms covers most industrial vibration from conveyors or compressors. The DC coil holding at 3.2 W means a 24 V DC supply needs only about 133 mA continuous per contactor — a 2 A supply can feed roughly 15 of these units simultaneously.","metaTitle":"Siemens 3RH1122-2BE40 SIRIUS Auxiliary Contactor, 10A AC-12,","metaDescription":"Siemens SIRIUS 3RH1122-2BE40 auxiliary contactor, size S00. 10A AC-12, 24V DC coil 3.2W. 2 NO + 2 NC.
