The spring-type terminals accept 2x (0.5 to 4 mm²) solid or stranded wire, and the unit snaps onto 35 mm DIN rail per DIN EN 50022 or mounts with screws. The 73 mm depth, 45 mm width, and 70 mm height define the envelope for DIN-rail spacing. ## Switching Capacity Across Voltages The auxiliary contacts on this contactor handle a range of voltage ratings: 10 A at 24 V, 10 A at 230 V, 3 A at 400 V, and 0.1 A at 600 V. At 48 V and 60 V the rating is 2 A; at 110 V it is 1 A; at 220 V it drops to 0.3 A; at 440 V it is 0.8 A; and at 125 V it is 2 A. These values reflect the switching capability of the built-in auxiliary switch across different control voltages — useful when the contactor drives both the main load and a signaling circuit from the same device.","metaTitle":"Siemens 3RT2516-2AB00 SIRIUS Contactor, Size S00, 24 V Coil,","metaDescription":"Siemens SIRIUS 3RT2516-2AB00 contactor, Size S00, 24 V AC/50-60 Hz coil, 10 A rated current.

The key difference is the coil voltage and terminal type — the 3RT2516-2AB00 uses a 24 V coil with spring terminals, while the 3RT2526-1AD20 uses a different coil voltage and screw terminals. Both share the same physical footprint and DIN-rail mounting, so a panel designed for one can typically accept the other without rewiring, provided the coil supply matches."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2516-2AB00","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT2516-2AB00 when reusing this data.
