Technical Specifications

Version & Model Difference

The Siemens 3RT6018-1AB01 is part of the 3RT6 series, which replaced the older 3RT1 series. Compared to its predecessor, the 3RT6 series offers a more compact design, higher switching capacity, and improved energy efficiency. The 3RT6018-1AB01 specifically features a 24V DC coil, whereas other versions may have AC coils (e.g., 3RT6018-1AB00 with 24V AC) or different coil voltage ratings. Additionally, the 3RT6 series includes integrated auxiliary contacts (1 NO + 1 NC) as standard, which was optional in earlier series. This contactor is also compatible with a wider range of accessories, such as the new 3RH6 auxiliary contact blocks and 3RT6 surge suppressors.
