Front face carries IP20; the terminal area is IP00, meaning the wiring zone is open to the panel environment — plan gland plates and clearance accordingly. Pollution degree 3 rating covers industrial atmospheres with conductive deposits, so no additional conformal coating is required for typical control-panel use. The AC-3 motor-switching rating of 11 kW at 690 V defines the maximum three-phase induction motor load this contactor can handle under normal starting and running. At 400 V, AC-4 duty (plugging / inching) is rated 15.5 A — that is the current limit for frequent reversing or jogging cycles, which generate higher arcing stress than AC-3. The auxiliary contact ratings span 10 A at 24 V up to 0.3 A at 220 V; these are resistive loads on the control circuit, so verify your PLC output or relay coil draw against the curve. Main circuit terminals accept screw-type connections: solid/stranded up to 2x 10 mm² or 1x 8 AWG. Auxiliary terminals handle 2x (0.5–1.5 mm²) solid or 2x (0.75–2.5 mm²) stranded, max 2x 4 mm². For type 2 coordination (no-weld fault clearing), use gL/gG fuses at 25 A; type 1 coordination allows 63 A fuses. The 50/60 Hz coil operates at 0.8–1.1 times rated voltage — check your control transformer regulation if the line is weak.","metaTitle":"Siemens 3RT1025-1AK60 SIRIUS Power Contactor, 690 V 11 kW, 4","metaDescription":"Siemens 3RT1025-1AK60 SIRIUS power contactor, Size S0, 45 mm wide, 11 kW at 690 V, screw terminals, IP20 front, DIN rail mount.
