For standard AC-2 or AC-3 starting (slip-ring or squirrel-cage motors), it's rated 11 kW at 400 V. That's the number to match against your motor nameplate for continuous running. The auxiliary contact block carries 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for a PLC input or a holding circuit, but watch the voltage drop on long runs. ## Coordination and short-circuit protection This matters when you're laying out the MCC bucket — the fuse size determines the upstream breaker selectivity. Pollution degree 3 (industrial, conductive dust) and IP20 on the front, IP00 at the terminals mean it's meant for an enclosed panel, not open mounting. ## Operating conditions and wiring Rated for -25 to +60 °C ambient during operation, with a maximum operating altitude of 2 000 m. The screw terminals accept 2 x (0.25 to 2.5 mm²) solid or stranded, or up to 2 x 10 mm² for the main circuit — standard for panel wiring with ferrule or direct.","metaTitle":"Siemens 3RT1026-3AP60 SIRIUS Power Contactor, S0, 45mm, AC-4","metaDescription":"Siemens 3RT1026-3AP60 SIRIUS power contactor, S0 frame, 45mm width, screw terminals, AC-4 15.5A at 400V, 11kW AC-2/AC-3.

The 3RT1026-3AP60 uses a 24 V DC coil with 1 NO + 1 NC auxiliary; verify the coil voltage and contact arrangement before substituting."},{"question":"Will 3RT1026-3AP60 drop into a panel specified around 3RT1023-1AL20 without rewiring?","answer":"The physical footprint is the same — both are S0 frame, 45 mm wide, DIN-rail mount. The screw terminal layout for the main circuit is identical. However, the coil voltage differs; the 3RT1026-3AP60 runs on 24 V DC, while the 3RT1023-1AL20 may use a different coil. Check the coil supply before swapping."},{"question":"Where can I buy 3RT1026-3AP60 and what is the lead time?","answer":"This part is sourced and quoted to order through independent distribution.
