The 45 mm width and 85 mm height fit the S0 footprint — a common slot in Siemens SIRIUS distribution and motor starter assemblies. Front face carries an IP20 rating; the terminals themselves are IP00, meaning the wiring zone needs clearance from live parts in the enclosure. For Type 1 coordination (no damage to the enclosure, contactor may need replacement after a fault), the 3RT1024-1AC00 requires a gL/gG fuse rated at 63 A. For Type 2 coordination (contactor remains operational after a fault), the fuse drops to 25 A. That's the standard IEC 60947-4-1 distinction — pick the coordination type based on whether you want to reuse the contactor after a short circuit or just contain the arc.","metaTitle":"Siemens 3RT1024-1AC00 SIRIUS Power Contactor, 7.5 kW at 690","metaDescription":"Siemens SIRIUS 3RT1024-1AC00 power contactor, size S0, 3 NO main contacts, 7.5 kW at 690 V AC-3.

The difference is in the ratings — the 3RT1024-1AC00 carries higher motor power (7.5 kW vs the smaller frame sibling's rating) and different coil voltage.
