That means it handles standard three-phase induction motors up to 11 kW across the common European voltage range without derating the power. Main and auxiliary/control circuits use screw-type terminals. Wire ranges for main contacts accept 2x (1...2.5 mm²), 2x (2.5...6 mm²), max 2x 10 mm²; auxiliary/control terminals take 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²). Strip and torque per the terminal marking on the contactor. For Type 1 coordination (device may be damaged but no fire risk) the fuse can be gL/gG 100 A. The 35 A limit is the one to design for if uptime matters — you clear the fault without welding the main contacts. ## Environmental and operating range The coil operates at 50/60 Hz with a rated control supply voltage of 100 V at 50 Hz and 110 V at 60 Hz. Coil draw at 24 V rated value is 10 A — that's the inrush, not the hold; the actual sealed VA is lower. Front-face protection is IP20; terminal area is IP00 — the contactor is designed for enclosure mounting, not open-panel washdown.","metaTitle":"Siemens 3RT1026-1AG10 SIRIUS S0 Power Contactor, 11 kW at 40","metaDescription":"Siemens 3RT1026-1AG10 SIRIUS S0 power contactor. 11 kW at 400 V AC-3, 15.5 A AC-4.

The main difference is the coil voltage — the -1AG10 uses a 100-110 V 50/60 Hz coil, while the -1AB00 uses a 24 V AC/DC coil. They share the same footprint, terminal layout, and mounting rail, so panel rewiring is not required if the coil supply matches."},{"question":"What is the depth of the 3RT1026-1AG10?","answer":"The depth is 91 mm.
