Rated operational current is 10 A at 24 V, derating to 6 A at 230 V and 1 A at 690 V. Pollution degree 3 applies per the datasheet. Depth is 72 mm, which is the dimension to account for when spacing against the gland plate or adjacent devices. Terminal capacity accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12. Shock resistance is rated at 10g for 5 ms and 5g for 10 ms.","metaTitle":"Siemens 3RH1122-1BK80 SIRIUS Auxiliary Contactor, 52 V DC Co","metaDescription":"Siemens SIRIUS 3RH1122-1BK80 auxiliary contactor, 52 V DC coil, 2 NO contacts, size S00, IP20 front.
