Rated for AC-3 duty at 7.5 kW on both 500 V and 690 V supplies, this contactor handles three-phase induction motors up to that power class. For Type 1 coordination, a 63 A gL/gG fuse protects the contactor; for Type 2 coordination (limited weld risk), the fuse drops to 25 A gL/gG. The 45 mm wide, 85 mm high, 140 mm deep footprint fits the S0 frame standard. The built-in auxiliary contact block (1 NO + 1 NC) carries a rated operational current of 10 A at AC-12 (resistive loads). For DC switching, the ratings are: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V AC. The coil operates at 50 Hz with a voltage tolerance of 0.8 to 1.1 times the rated voltage (48 V).","metaTitle":"Siemens 3RT1024-1AH04 SIRIUS Power Contactor, 7.5 kW at 690","metaDescription":"Siemens SIRIUS 3RT1024-1AH04 power contactor, Size S0, 3-pole NO, 7.5 kW at 690 V AC-3, 12.5 A AC-4 at 400 V.

The delta is in the coil voltage and auxiliary contact configuration — the 3RT1023-1AL20 uses a different coil rating and may have a different auxiliary contact arrangement. Check the coil voltage on your BOM before substituting; the main contact ratings and mounting footprint are identical."},{"question":"Will 3RT1024-1AH04 drop into a panel specified around 3RT1023-1AL20 without rewiring?","answer":"The mechanical footprint is identical — both are Size S0, 45 mm wide, with the same DIN-rail mounting and screw terminal layout. The main power wiring will transfer directly. The only potential difference is the coil voltage and auxiliary contact configuration, so verify those before installation."},{"question":"How do I get current pricing and availability for 3RT1024-1AH04?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
