The 45 mm width and 85 mm height keep it compact for dense rail layouts. Side-by-side mounting is supported, which means no mandatory spacing between contactors on the same rail. ## Termination and wiring Main and auxiliary circuits use screw-type terminals. The main contacts accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). For AWG, that's 2x (16 to 12), 2x (14 to 10), or 1x 8. Auxiliary terminals take 2x (20 to 16), 2x (18 to 14), or 1x 12 AWG. These ranges cover common panel wire sizes without needing terminal reducers. ## Protection and coordination For type 1 coordination (contactor may need replacement after fault), the fuse can be gL/gG 100 A. The front panel is IP20 (finger-safe), while the terminals are IP00 (no finger protection at the wiring point — panel builders should account for this in enclosure design). The part complies with RoHS substance prohibitance dated July 1, 2006, covering the standard EU RoHS scope.","metaTitle":"Siemens 3RT1026-1AP00-ZW98 SIRIUS Power Contactor, S0, 3NO,","metaDescription":"Siemens 3RT1026-1AP00-ZW98 SIRIUS S0 power contactor, 3NO main contacts, rated 11kW at 400V AC-2.
