For AC loads, the contacts handle 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. These ratings define the maximum continuous current the contacts can make and break at the respective voltage levels — important when matching to the load's inrush and steady-state draw. ## Coil and mechanical data The contactor is rated for 10,000,000 mechanical operations typical, with a maximum switching frequency of 10,000 1/h at AC. ## Mounting and environmental conditions","metaTitle":"Siemens 3RH2244-2BD80 SIRIUS Auxiliary Contactor, 115 V DC,","metaDescription":"Siemens 3RH2244-2BD80 SIRIUS auxiliary contactor, size S00, 4 NO contacts, 115 V DC coil.
