These ratings cover typical PLC digital inputs, relay coils, and indicator lamps. The 10 A at 230 V AC rating means this auxiliary can directly switch a moderate-sized contactor coil or a bank of solenoid valves without an interposing relay. The DC-13 ratings (inductive DC loads) are the limiting factor for DC control circuits: 6 A at 60 V DC drops to 0.3 A at 220 V DC. For 24 V DC control, the 10 A rating applies — adequate for most PLC output modules. ## Mechanical and Environmental Fit The S0 frame size measures 97 mm deep by 60 mm wide by 85 mm high — a compact footprint that fits standard 35 mm DIN rail per DIN EN 60715. The screw-and-snap-on mounting allows tool-free installation and removal for panel servicing. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. This covers most indoor industrial environments including unheated warehouses and panel interiors near machinery. Mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° forward/backward tilt. This accommodates tight enclosures or angled sub-panels without derating. ## Wiring and Termination Details Main contact wiring accepts stranded conductors from 1 to 10 mm². Auxiliary and coil terminals accept solid wire in two sizes: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). The coil uses screw-type terminals (not cage clamps) — ensure a proper torque driver is available during panel assembly. The AC coil draws 0.25 VA at 50 Hz and 0.28 VA at 60 Hz, negligible for most control transformers. Clearance distances: 10 mm upwards and forwards, 10 mm downwards, 6 mm at the sides. These are the minimum air gaps to adjacent metalwork or other devices for proper heat dissipation and arc clearance. ## Mechanical Endurance and Switching Performance Mechanical endurance is rated at 10 million operations typical — this is the expected life before mechanical wear (spring fatigue, pivot wear) rather than electrical contact erosion. In a cycling application at 1 operation per second, that is over 115 days of continuous duty. Arcing time is 10 ms (fixed), with a make time of 4 to 16 ms and break time of 4 to 16 ms at AC. These switching times are consistent across the operating range and are compatible with standard PLC scan cycles.","metaTitle":"Siemens 3RT2325-1AK60 SIRIUS Contactor, Size S0","metaDescription":"Siemens SIRIUS 3RT2325-1AK60 contactor, size S0, screw-type coil terminals, AC coil, 1 NO + 1 NC auxiliary contacts.
