The built-in varistor surge suppressor clips the inductive kick on coil de-energization, which keeps transients off the backplane and extends the life of solid-state outputs. Rated surge voltage resistance at 6 kV aligns with IEC 60947-1 coordination requirements for basic insulation in industrial control panels. This auxiliary contactor carries 2 NO + 2 NC instantaneous contacts. AC-15 / DC-13 switching capacities are given at several voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. The 110 V DC rating is 1 A, dropping to 0.27 A at 220 V DC. For an integrator, the 690 V AC rating means this contactor can switch control transformer primaries or small heater loads at line voltage without derating. Terminal capacity accepts 2 × (0.25 … 2.5 mm²) solid or stranded — standard for control wiring up to 14 AWG.","metaTitle":"Siemens 3RH1122-2KV80-0LA0 SIRIUS Auxiliary Contactor, 34 V","metaDescription":"Siemens SIRIUS 3RH1122-2KV80-0LA0 auxiliary contactor, 34 V DC coil, size S00, 4 contacts, IP20 front.
