The Siemens SIRIUS 3RT1516-2AB00 is a size S00 power contactor with a 24 VAC 50/60 Hz coil. It is rated for switching loads across a range of voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 2 A at 60 V, among others. The auxiliary contacts are rated 9 A per NO and per NC contact. This is a current-production part.
The 45 mm width and 60 mm height fit standard S00 contactor spacing.
Main circuit terminals are spring-loaded, accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded conductors. Auxiliary circuit terminals accept 2x (0.25 to 2.5 mm²). The spring-cage design reduces wiring time and ensures consistent clamping force, important for high-vibration environments.
Environmental and Protection
Rated IP20 on the front and at the terminals, suitable for installation inside a control cabinet. Maximum operating altitude is 2000 m. The contactor is designed for standard industrial environments without washdown exposure.
