Screw-type terminals on the main circuit accept 2x 0.5–1.5 mm² solid or 2x 0.75–4 mm² stranded, with a max of 2x 10 mm² per clamp. ## Motor duty and coordination At 400 V AC-2 the contactor switches 11 kW motor loads; in AC-4 (frequent reversing or inching) it handles 15.5 A. For Type 2 coordination (no weld) the recommended upstream fuse is gL/gG 35 A; Type 1 coordination allows a 100 A gL/gG fuse. The coil draws 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — verify the control transformer sizing against these inrush figures. Side-by-side clearance is 6 mm; front protection is IP20, terminal area is IP00.","metaTitle":"Siemens 3RT1026-1AL20-ZX95 SIRIUS Power Contactor, S0, 45 mm","metaDescription":"Siemens SIRIUS 3RT1026-1AL20-ZX95 power contactor, size S0, 45 mm wide, 91 mm deep.
