For AC-2 at 400 V it handles 7.5 kW, covering slip-ring motor starting. Side-by-side mounting is allowed — no derating gap required for adjacent units at rated load, but watch the 6 mm clearance to grounded metal on the side for arc flash containment. Main circuit terminals accept solid or stranded wire: 2x (0.25–2.5 mm²) fine-stranded, 2x (1–2.5 mm²) single/stranded, 2x (2.5–6 mm²), or up to 2x 10 mm². AWG equivalents: 2x (16–12), 2x (14–10), 1x 8. For type 2 coordination (no-weld after fault), use gL/gG fuses rated 25 A; for type 1 (welding allowed but safe), 63 A fuses fit. Auxiliary contact ratings: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — all at 50 Hz. Coil data is not in this listing; verify coil voltage from the nameplate before wiring.","metaTitle":"Siemens 3RT1025-3AD00 SIRIUS Power Contactor, 3 NO, S0, 45mm","metaDescription":"Siemens SIRIUS 3RT1025-3AD00 power contactor, S0 frame, 3 NO main contacts, 45mm wide, screw terminals, rated 11 kW at 690 V.
