It carries an integrated auxiliary switch rated for 10 A at 230 VAC, making it a common choice for motor control and general switching in industrial control panels. The 230 VAC coil (rated at 50 Hz and 60 Hz) pulls 0.25 A at 50 Hz and 0.28 A at 60 Hz — a modest draw that a standard control transformer can support, but worth checking if you are daisy-chaining multiple contactors on a single 24 VDC supply (this is AC, not DC). The auxiliary contact ratings span from 10 A at 24 VAC down to 0.1 A at 600 VAC, covering pilot duty and PLC input signals across common control voltages. The 10 A rating at 230 VAC is the headline figure for general-purpose signaling. Mechanical endurance: 10,000,000 operating cycles typical. S0 frame: 60 mm wide, 102 mm high, 97 mm deep. Main contact terminals accept solid wire from 2x 0.5 to 2.5 mm² and stranded from 1 to 10 mm². The coil connection uses spring-type terminals, which speed up wiring but require a ferrule on stranded wire for a gas-tight connection. Mounting position is standing on a horizontal surface — standard for DIN-rail panels. Up to two attachable auxiliary contact blocks can be added for expanded signaling needs. If you are cross-referencing against a different SIRIUS variant (like a 3RT2027-2AV00), the S0 frame size and 230 VAC coil are the same, but the auxiliary contact configuration and terminal layout may differ — verify the wiring diagram before assuming a drop-in swap.","metaTitle":"Siemens 3RT2325-2AL20-1AA0 SIRIUS S0 Contactor, 230 VAC Coil","metaDescription":"Siemens SIRIUS 3RT2325-2AL20-1AA0 S0 contactor. 230 VAC 50/60 Hz coil. 10 A auxiliary rating at 230 VAC.
