Front protection is IP20, meaning it's touch-safe but not sealed against moisture — suitable for dry indoor panel environments. The maximum continuous current is 10 A, but the actual rating depends on the voltage and duty. For DC control circuits, the rated operational current at 24 V is 10 A, dropping to 6 A at 125 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — the arc-extinction limit governs the lower currents at higher DC voltages. For AC-15 inductive loads (typical for solenoid valves and contactor coils), the rated current at 24 V is 10 A, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 0.5 A at 440 V, and 0.26 A at 600 V. The AC-15 rating at 690 V is 1 A. These are the numbers to use when sizing for coil loads. Mechanical service life is 10 million switching cycles, with contact reliability of 1 faulty switching per 100 million operations at 17 V, 1 mA.","metaTitle":"Siemens 3RH1911-1FB22-ZW98 SIRIUS Auxiliary Switch Block, 10","metaDescription":"Siemens SIRIUS 3RH1911-1FB22-ZW98 auxiliary switch block, 10 A rated, 1 NO + 1 NC + 1 instantaneous contact.
