Three normally-open main contacts handle the power path; the screw-type terminals accept 2x (1... 2.5 mm²) stranded or solid, with a max of 2x 10 mm². For control-circuit or resistive loads, AC-12 maximum operating current is 10 A. The coil draws 0.8 to 1.1 A at 50 Hz, 110 V nominal. IP20 on the front, IP00 at the terminals: panel builders should guard the live screw terminals behind a door or cover. The 45 mm width and 85 mm height fit the S0 envelope — common on DIN-rail assemblies alongside overload relays and busbars. Screw terminals accept 2x (1... 2.5 mm²) for control wiring; main power conductors can go up to 2x 10 mm² or a single 10 mm². The solid wire range is 2x (0.25... 2.5 mm²). Auxiliary contact block options (not included here — this is a bare 3-pole main contactor) snap onto the front or side.","metaTitle":"Siemens 3RT1024-3AF04-ZW95 SIRIUS Power Contactor, S0, 7.5 k","metaDescription":"Siemens SIRIUS 3RT1024-3AF04-ZW95 power contactor, size S0, 3 NO main contacts, 7.5 kW at 690 V, 5.5 kW AC-2 at 400 V.

The key difference is in the coil voltage and power ratings — verify your specific load and coil requirements before substituting."},{"question":"What is the depth of 3RT1024-3AF04-ZW95?","answer":"The depth is 140 mm, measured from the DIN-rail mounting surface to the front of the contactor housing."},{"question":"What solid wire range does the 3RT1024-3AF04-ZW95 accept?","answer":"The screw terminals accept 2x (0.25... 2.5 mm²) solid conductors."},{"question":"Will 3RT1024-3AF04-ZW95 drop into a panel specified around 3RT1023-1AL20?","answer":"Yes, both are S0 frame size — same 45 mm width, 85 mm height, 140 mm depth, and 35 mm DIN-rail snap-on mounting. The terminal layout is identical. The main difference is the coil voltage and motor power ratings; confirm those match your circuit before the swap."},{"question":"What compliance documentation does Siemens provide for 3RT1024-3AF04-ZW95?","answer":"As a SIRIUS product, this contactor carries CE marking for the European market and is designed to meet IEC 60947-4-1.
