This S0-size device includes three normally-open main contacts with no auxiliary contacts, optimized for compact control-panel layouts while supporting side-by-side mounting. The contactor is rated for demanding operating categories such as AC-3 and AC-4 and supports both AC and DC load paths. As a discontinued Siemens product, it is used primarily as a replacement unit for legacy machinery, CNC equipment, and industrial control panels. Key Features: 11 kW AC-3 Rating: Suitable for motor loads up to 11 kW at 400/500/690 V. 230 V AC Coil (50/60 Hz): Wide operating range: 0.8–1.1× (50 Hz) and 0.85–1.1× (60 Hz). S0 Contactor Size: Compact industrial design for efficient control-panel integration. 3-Pole Main Contact Set: Three normally-open main contacts with no auxiliary contacts. High Mechanical Durability: Up to 10 million mechanical switching cycles typical. Strong Electrical Ratings: 25 A AC-3 at 400 V; 40 A AC-1 at 400–690 V. Multi-Path DC Switching: Supports DC-1 and DC-3 loads with 1-, 2-, or 3-path series switching options. IP20/IP00 Protection: IP20 at the front, IP00 at terminals for safe internal mounting. Flexible Installation: Snap-on or screw mounting onto 35 mm DIN rail (EN 50022). Robust Screw-Type Terminals: Accepts a wide range of solid, stranded, and AWG conductors. The 3RT1026-1AL20 delivers the reliability and precision required for motor switching, control-circuit integration, and industrial automation.
