Rated for 1 000 operating cycles per hour at AC-1, AC-2, AC-3, and AC-3e duty, and 300 cycles per hour at AC-4. That means it handles frequent motor starting and stopping in conveyor or pump applications without derating the mechanical life of 10 000 000 typical operations. The auxiliary contact block carries 10 A at 24 VDC, 2 A at 48 VDC and 60 VDC, 1 A at 110 VDC, 0.9 A at 125 VDC, and 0.3 A at 220 VDC — useful for signaling back to a PLC or relay logic at different control voltages. Main contacts accept solid or stranded wire from 1 to 10 mm² (one conductor) or 2x (0.5 to 1.5 mm²) / 2x (0.75 to 2.5 mm²) for two conductors. The screw-type terminals are standard for panel builders — no special tooling needed. The S0 frame size (45 mm wide) fits alongside other SIRIUS components on the same DIN rail, keeping the panel layout dense.","metaTitle":"Siemens 3RT2025-1BJ80 SIRIUS S0 Power Contactor, 24 VDC Coil","metaDescription":"Siemens 3RT2025-1BJ80 SIRIUS S0 power contactor, 24 VDC coil, screw terminals.
