The auxiliary switch is present, and the coil is screw-type. Arcing time is 10 to 10 ms (AC), with an AC arcing range of 4 to 16 ms. ## Switching ratings across voltages Rated switching currents at various AC voltages: 10 A at 24 V, 2 A at 48 V, 6 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 10 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 0.1 A at 600 V. The 230 V rating matches the 24 V rating, which is unusual — most contactors derate at higher voltages. This part holds its current up to 230 V, then drops off.","metaTitle":"Siemens 3RT2325-1AG20 SIRIUS Contactor, AC Coil, Size S0","metaDescription":"Siemens SIRIUS 3RT2325-1AG20 contactor, size S0, AC coil 110 V 50/60 Hz, screw terminals, 10 A at 24 V, 10 A at 230 V.
