Rated 10 A in AC-12 duty (resistive loads at 24 V), it handles the control-circuit switching common in PLC output isolation and small heater banks. The 65 mm width and 85 mm height leave room for auxiliary contact blocks alongside. Main and auxiliary/control circuits use screw-type terminals. Main terminals accept solid wire 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²); stranded accepts 2x (1–2.5 mm²), 2x (2.5–6 mm²), or max 2x 10 mm². AWG equivalents are 2x (16–12), 2x (14–10), 1x 8 for main contacts. Type 1 coordination (contactor may need replacement after fault) allows a 100 A gL/gG fuse. RoHS compliance date is 2006-07-01, meaning it meets the original EU RoHS directive. No REACH or UL listing is explicitly stated in the spec record, but as a Siemens industrial control product it typically carries CE marking and UL recognition — verify the specific UL file number against your panel's listing requirements.","metaTitle":"Siemens 3RT1026-1BB46-1AA0 SIRIUS Power Contactor, 24 VDC, 1","metaDescription":"Active-production Siemens SIRIUS power contactor 3RT1026-1BB46-1AA0, 24 VDC coil, 10 A AC-12, size S0, screw terminals, IP20 front.
