The 60 mm wide, 85 mm tall, 107 mm deep footprint fits standard S0 contactor spacing. Side clearance of 6 mm to adjacent devices; 10 mm clearance upward, downward, and forward. Stranded main-circuit wiring accepts 1 to 10 mm²; auxiliary terminals take 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded. The arcing time on the main contacts is 10 to 10 ms, and the DC coil dropout timing is 15 to 18 ms. The auxiliary switch is rated for DC switching across the voltage range, not just a single point. At 24 V it handles 10 A — enough for a bank of solenoid valves or indicator lamps. At 48 V the rating drops to 2 A, and at 125 V to 0.9 A. The 230 V rating is 10 A, but that is an AC value. For DC loads above 60 V, derate to the listed DC curve: 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 0.1 A at 600 V, and 1 A at 690 V. The full-scale value of 1.1 and initial value of 0.8 likely refer to the coil pickup and dropout multipliers — the coil holds at 80% of rated voltage and picks up at 110%.","metaTitle":"Siemens 3RT2325-1BG40 SIRIUS Contactor, S0 Frame, 24 VDC Coi","metaDescription":"Siemens 3RT2325-1BG40 SIRIUS contactor, size S0, 24 VDC screw-type coil.
