The 11 kW rating at 500 V and 690 V AC-3 tells you this contactor handles standard squirrel-cage motor starting without welding the contacts — AC-3 covers starting and disconnecting a running motor. For resistive loads (AC-1), the maximum operating current is 10 A at 400 V. The mechanical endurance is 10 million operations, so the contactor outlasts most motor-driven machinery cycles. Short-circuit protection coordination is specified: type 2 coordination requires a gL/gG fuse rated 35 A, while type 1 coordination allows a 100 A gL/gG fuse. Type 2 means the contactor remains usable after a fault — no welding or damage — which matters for production lines where downtime for replacement is expensive. ## Termination and wiring constraints Main circuit terminals are screw-type, accepting solid conductors from 2x 0.5 mm² up to 2x 4 mm², or stranded conductors from 2x 1 mm² up to 2x 10 mm² (single conductor). AWG equivalents are 2x 16–12 solid or 2x 14–10 stranded, with a single 8 AWG maximum. ## Environmental limits and mounting Side-by-side mounting is permitted, with 6 mm clearance required at the side for heat dissipation. The contactor depth is 140 mm, height 85 mm, width 45 mm.","metaTitle":"Siemens 3RT1026-1AP04-ZW96 SIRIUS Power Contactor, S0, 11 kW","metaDescription":"Siemens SIRIUS 3RT1026-1AP04-ZW96 power contactor, size S0, 3 NO main contacts, rated 11 kW at 500 V / 690 V AC-3.

It will not directly replace the 3RT1026-1AP04-ZW96 (size S0) without verifying the load current and coordination requirements — the S0 frame carries higher AC-3 and AC-4 ratings."},{"question":"What is the depth of this contactor?","answer":"The depth is 140 mm, which is the dimension from the DIN rail mounting surface to the front of the contactor body."},{"question":"What solid conductor cross-sections does it accept?","answer":"The main terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and maximum 2x (0.75 to 4 mm²)."},{"question":"Will 3RT1026-1AP04-ZW96 drop into a panel specified around 3RT1023-1AL20 without rewiring?","answer":"Both are 45 mm wide and mount on 35 mm DIN rail, so the physical footprint is the same.
