Switching frequency varies by duty class: up to 1 000 operations per hour at AC-1, AC-2, AC-3, and AC-3e maximum, and 300 operations per hour at AC-4 maximum. This means the contactor handles high-cycle motor starting (AC-3) at full rated current without derating, while the lower AC-4 rate accounts for the heavier wear of inching and plugging duty. Main contact terminals accept solid or stranded wire from 1 to 10 mm²; auxiliary contact terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). Wire preparation is straightforward with screw terminals — no special ferruling required for stranded up to 10 mm². Dimensions: Width 45 mm, Height 85 mm, Depth 97 mm.","metaTitle":"Siemens 3RT2025-1AF00 SIRIUS Power Contactor, Size S0, 24 VD","metaDescription":"Siemens 3RT2025-1AF00 SIRIUS power contactor, Size S0, 24 VDC coil, 10 A at 24 V rated value, screw terminals, snap-on DIN rail mounting.
