That rating means it handles a 3-phase induction motor of that power on a 690 V line, which is common in mining conveyors and heavy industrial drives. The spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or stranded wire, so no ring lugs needed — just strip and push, which saves time on a panel build or a field swap. Depth is 114 mm, which is typical for S00 contactors with spring terminals; check your enclosure depth if you're retrofitting into a shallow gland plate. Front IP20 means finger-safe, but the terminals themselves are IP20 as well — no special cover needed for a standard panel. The headline motor-switching numbers: 3.5 kW at 500 V and 4 kW at 690 V under AC-3 duty — that's the standard category for squirrel-cage motors during starting and running. For resistive loads (AC-1), the contactor can carry up to 10 A continuously. For reversing or plugging duty (AC-4), the rated current is 6.5 A at 400 V, which is lower than the AC-3 figure; that's because AC-4 involves inching or counter-current braking, which stresses the contacts more. For type 1 coordination (the contactor may need replacement but the panel stays safe), use a 35 A fuse. That's useful info for the panel builder designing the branch circuit — it tells you exactly what upstream fuse to spec so the contactor survives a fault. The contactor itself has a mechanical life of 30 million operations typical, which is standard for S00 contactors and fine for most cyclic loads.","metaTitle":"Siemens 3RT1015-2AF04-ZW95 SIRIUS Power Contactor, S00, 4 kW","metaDescription":"Siemens SIRIUS 3RT1015-2AF04-ZW95 power contactor, size S00, 4 kW at 690 V, spring-loaded terminals, IP20 front, snap-on DIN rail.
