For resistive loads (AC-1), the contactor can handle the full 10 A continuous per pole at 24 V DC. DC switching capability: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V. These numbers drop fast as voltage rises because DC arcs are harder to extinguish — the 24 V figure is the one you'll use in most control panels. Main circuit terminals: screw-type, accepting 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²) solid or stranded. AWG equivalents: 2x (20...16), 2x (18...14), 1x 12. Auxiliary and control circuit terminals are also screw-type, same wire ranges. Finely stranded with core-end processing: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²). Type 2 requires 35 A. That's the upstream short-circuit protection the contactor expects.","metaTitle":"Siemens 3RT1326-1XX40-0VA1 SIRIUS Power Contactor, 24 VDC, 1","metaDescription":"Siemens SIRIUS 3RT1326-1XX40-0VA1 power contactor, size S0, 4 NO main contacts, 24 VDC coil, 11 kW at AC-2 400 V.
