Siemens 3RT1015-2AP01-ZX95 SIRIUS Power Contactor – Size S00, 24 VDC Coil
The coil is rated for 24 VDC, and the contactor carries DC-1 switching ratings of 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — so for a 24 VDC control circuit it handles the full rated current, but derates significantly as voltage climbs. For AC motor duty, it is rated 3 kW at 400 V in AC-2 (slip-ring motor starting) and 6.5 A at 400 V in AC-4 (plugging/reversing), which tells you this is sized for small motor loads up to about 4 kW at 690 V.
Termination and Wiring
Main current circuit connections use spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded wire, or 2x (24... 14) AWG. That's a standard terminal range for Size S00 — no special crimp tool needed for the spring cage, but make sure the strip length is clean to avoid whiskers under the clamp. The front face carries IP20 protection; the terminal area is also rated IP20, so it's touch-safe in a closed panel but not suitable for washdown environments.
For Type 2 coordination (contactor remains operational after a fault), the fuse must be gL/gG 20 A.
