It switches motor loads up to 11 kW in AC-2 duty at 400 V, and handles 15.5 A in AC-4 (reversing or inching) at the same voltage. The built-in varistor surge suppressor is already wired across the coil, so you don't need to add a separate snubber for inductive load switching. The AC-2 rating of 11 kW at 400 V covers slip-ring motor starting — the contactor sees moderate inrush but makes and breaks under load. The auxiliary contact ratings are given per voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V — so the 24 V control circuit can handle a full 10 A through the aux contacts without derating. For Type 1 coordination (no weld prevention, just no fire or shock hazard after a short), the upstream fuse can be gL/gG 100 A. For Type 2 coordination (contactor remains usable after a fault), drop to gL/gG 35 A. The screw terminals accept 2x 0.75 to 4 mm² on the control side, and 2x 1 to 10 mm² on the main circuit — AWG equivalents are 2x 16-12 and 2x 14-10 respectively.","metaTitle":"Siemens 3RT1026-1XP00-0GA0 SIRIUS Power Contactor, S0, 11 kW","metaDescription":"Siemens SIRIUS power contactor 3RT1026-1XP00-0GA0, size S0, 11 kW at 400 V AC-2, built-in varistor.
