The 7.5 kW rating at 690 V AC-3 is the motor-switching capacity — it handles a 3-phase motor load up to that power at 690 V line voltage. At 500 V the same motor power rating holds, so the contactor is not derated across that voltage band. The coil is rated for 24 V at both 50 Hz and 60 Hz, with an operating range of 0.8...1.1 times rated voltage at 50 Hz and 0.85...1.1 at 60 Hz. That means the coil holds in reliably down to about 19.2 V at 50 Hz and 20.4 V at 60 Hz — useful if the control transformer sags under load. Size S0 means a 45 mm wide footprint — three of these fit in a standard 135 mm DIN-rail section. Screw terminals accept 2x (0.25...2.5 mm²) solid or stranded, up to 2x 10 mm² maximum. Type 1 coordination requires a 63 A gL/gG fuse upstream;","metaTitle":"Siemens 3RT1024-3AC20-ZX95 SIRIUS Power Contactor, 7.5 kW at","metaDescription":"Siemens SIRIUS 3RT1024-3AC20-ZX95 power contactor, size S0, 7.5 kW at 690 V AC-3, 24 V 50/60 Hz coil, screw terminals, snap-on DIN rail.
