The 45 mm width and 85 mm height keep it compact for dense panel builds. Front-side protection is IP20, so it's safe for finger contact inside an enclosure; the terminals themselves are IP00, meaning the wiring compartment expects enclosure protection from the panel builder. The AC-4 rating of 12.5 A at 400 V is the one that governs frequent inching or plugging duty — if your application cycles the motor on and off under load, this is the current limit that matters, not the higher AC-3 figure. Auxiliary contact ratings cover 24 V at 10 A down to 220 V at 0.3 A, so the same block handles both PLC-level signals and small relay loads without a separate interface. Main and auxiliary circuits use screw-type terminals. Main terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded — that covers most panel wire sizes up to 4 mm². Auxiliary terminals take 2x (1 to 2.5 mm²) solid or stranded, or max 2x 10 mm². For Type 2 coordination (no-weld fault clearing), the required upstream fuse is 25 A gL/gG. For Type 1 coordination (device may be damaged but arc contained), the fuse can go up to 63 A gL/gG. This matters when you're coordinating with the MCCB or fuse in the feeder. Substance prohibition per RoHS applies from July 1, 2006, so the part is RoHS-compliant for EU and most global markets. The IEC 81346-2 reference code is Q, which designates it as a switching device in the plant documentation standard.","metaTitle":"Siemens 3RT1024-1AG20 SIRIUS Power Contactor, S0, 7.5 kW at","metaDescription":"Siemens SIRIUS 3RT1024-1AG20 power contactor, size S0.
