The contactor carries an integrated RC surge suppressor across the coil, which saves you an external snubber on inductive loads like motor starters or solenoid valves. The front face is rated IP20 (finger-safe), and the terminals themselves are IP00 — standard for a panel-mount power device. The AC-3 motor-switching rating of 7.5 kW at 690 V (or 7.5 kW at 500 V) tells you this contactor handles a standard 10 HP motor at 480 V and a 7.5 kW motor at 690 V. For resistive loads (AC-12), the maximum operating current is 10 A. The auxiliary contact block is rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — so it can switch a PLC output or a small relay coil without a separate interposing relay. The screw terminals accept solid conductors from 0.25 to 2.5 mm² (two per clamp) and stranded up to 6 mm², with a maximum of 10 mm² per terminal. The recommended fuse for type 2 coordination is a 25 A gL/gG — this limits fault energy so the contactor survives a short circuit without welding. Because it's an active part, there's no urgency to stockpile or find a substitute. If you're specifying it into a new design, the S0 frame size and 45 mm width are common across the SIRIUS contactor family, so panel layout and wiring practice carry over to other ratings.","metaTitle":"Siemens SIRIUS 3RT1024-3EL24-0KS0-ZX95 Power Contactor, S0,","metaDescription":"Siemens SIRIUS power contactor 3RT1024-3EL24-0KS0-ZX95, S0 size, 7.5 kW at 690 V, 45 mm wide, IP20 front, RC suppressor, screw terminals.
