What this SIRIUS auxiliary contactor does in a panel
The Siemens 3RH2262-4AM20 is a SIRIUS auxiliary contactor — it switches control signals and low-power loads in a motor starter or PLC output circuit, not the main motor current. It carries 6 instantaneous contacts, meaning all six switch without delay when the coil picks up — no timed or delayed contacts in this variant.
Lifecycle and sourcing — what to expect on a BOM line
The 10% minimum relative humidity spec means it handles dry environments without contact oxidation issues from lack of moisture.
