It ships with two 3RT2028-1AP60 contactors pre-wired for direction reversal, saving panel space and wiring time compared to building the interlock yourself. The 18.5 kW at 400 V AC-3 rating means this assembly handles reversing duty on a standard 3-phase induction motor up to that power — typical for conveyors, hoists, or pump stations where forward/reverse is needed. The AC-3 category covers starting and plugging of squirrel-cage motors, so the contactors are sized for the inrush without welding contacts. Size S0 frame (90 mm wide, 101 mm high, 97 mm deep) fits into the common 35 mm DIN-rail panel layout. Main current circuit and coil both use screw-type terminals. Solid wire capacity: 2x (1... 2.5 mm²) and 2x (2.5... 10 mm²). Stranded: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). This covers standard panel wiring from control to power circuits.","metaTitle":"Siemens SIRIUS 3RA2328-8XB30-1AP6 Reversing Contactor, 18.5","metaDescription":"Siemens SIRIUS 3RA2328-8XB30-1AP6 reversing contactor assembly, Size S0, 18.5 kW at 400 V AC-3.

The 3RA2328-8XB30-1AP6 is a higher-rated assembly (18.5 kW vs the 3RT2027-1AP60's lower rating), so it will physically fit but may require checking the upstream protection and cable sizing for the higher current."},{"question":"What are the key dimensions for panel layout?","answer":"Width 90 mm, height 101 mm, depth 97 mm.
