Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded wire, which saves a screwdriver turn on the line but needs a proper ferrule for stranded below 0.5 mm². Auxiliary contact ratings: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V DC — the DC curve drops fast, so verify your inductive DC load against the 220 V / 0.3 A line. The IP20 finger-safe front terminals mean the panel builder can leave the gland plate open during commissioning without shock risk, but the contactor itself is not washdown-rated.","metaTitle":"Siemens 3RT1016-2AN21-1AA0 SIRIUS Power Contactor, Size S00,","metaDescription":"Siemens SIRIUS 3RT1016-2AN21-1AA0 power contactor, Size S00, 5.5 kW at 690 V, AC-4 8.5 A, spring-loaded terminals, current lifecycle.
