For resistive loads (AC-12), the maximum operating current is 10 A. ## Wiring and coordination specifics Screw terminals on the main circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid wire — or 2x (1 to 2.5 mm²) and up to 2x 10 mm² stranded. AWG equivalents are 2x (16 to 12) and 2x (14 to 10) for the smaller range, with a single 8 AWG maximum. This covers most panel wiring up to about 4 kW motor circuits directly. The 6 mm side clearance is the minimum for side-by-side mounting without derating. Maximum altitude is 2 000 m. The reference code Q per DIN EN 81346-2 indicates it is intended as a power switching device in the functional schematic — useful for documentation traceability when matching nameplates to panel drawings.","metaTitle":"Siemens 3RT1026-1BB40-ZW96 SIRIUS Power Contactor, S0, 24 VD","metaDescription":"Siemens 3RT1026-1BB40-ZW96 SIRIUS power contactor, size S0, 24 VDC coil, 11 kW at 500/690 V.
