It handles AC-2 duty at 5.5 kW at 400 V and AC-4 switching at 12.5 A at 400 V — that covers reversing or inching applications where the contacts break full motor current. Snaps onto 35 mm DIN rail per EN 50022 (screw and snap-on mounting) and measures 45 mm wide by 85 mm tall by 140 mm deep — fits a standard panel footprint with room for side-by-side mounting. ## Duty ratings and coordination Type 2 coordination requires a 25 A gL/gG fuse upstream; Type 1 coordination allows a 63 A gL/gG fuse. Pick the coordination class based on whether you want the contactor to survive a short-circuit fault (Type 2) or accept replacement after a fault (Type 1). ## Termination and environment Main and auxiliary circuits use screw-type terminals. Main terminals accept 2x (1... 2.5 mm²) solid/stranded or up to 2x 10 mm² max; auxiliary terminals accept 2x (0.5... 1.5 mm²) solid up to 2x (0.75... 4 mm²) max. AWG equivalents: main 2x (16... 12) or 1x 8; aux 2x (20... 16) or 1x 12. Front face is IP20 (finger-safe), terminal area is IP00.","metaTitle":"Siemens 3RT1024-1AN24 SIRIUS Power Contactor, S0, 7.5 kW","metaDescription":"Siemens SIRIUS 3RT1024-1AN24 power contactor, Size S0, 7.5 kW at 690 V, screw terminals, IP20 front.
