What this SIRIUS S10 power contactor is and where it fits
The Siemens 3RT1467-2XB46-0LA2 is a SIRIUS power contactor in size S10, built for switching motor loads and resistive circuits in industrial control panels. It carries a 24 V DC coil and includes an auxiliary switch, so it handles both the main power path and a feedback or interlock signal without an add-on block. Mounting is by screw fixing through a single 11 mm hole, with the contactor body sized at 210 mm high, 145 mm wide, and 202 mm deep. The mounting position allows vertical surface orientation with +/-90° rotation and +/-22.5° tilt front-to-back, which gives panel builders flexibility in tight enclosures. The operating temperature range of -40 to +70 °C and storage range of -55 to +80 °C mean it can sit in unheated shelters or outdoor cabinets without derating for cold starts.
Key ratings and what they mean for your panel
The 24 V DC coil has a dropout delay of 80 to 100 ms, which is useful when sequencing multiple contactors — you get a predictable off-delay without an external timer. The arcing time of 10 to 15 ms is typical for this class and matters for coordinating fuse or breaker clearing times on a fault. Mechanical life is rated at 10 million operations typical, so for high-cycle applications like conveyor divert gates or press feeders this contactor will outlast many panel refreshes. The maximum switching rate is 600 operations per hour in AC-1 duty and 350 in DC-1, which sets the upper bound for rapid cycling applications like resistance heating or DC load banks. Auxiliary contact ratings span DC voltages from 24 V (6 A) up to 480 V (156 A) — note that the 480 V figure likely reflects an AC rating on the same contact block, so verify the specific DC load curve for your application. For typical 24 V DC control circuits, the 6 A rating gives plenty of headroom for PLC inputs and relay coils. Solid conductor capacity accepts 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or max 2x 0.75 to 4 mm², covering standard control wiring sizes with room for double ferrules. Clearance distances are specified as 10 mm upwards, 20 mm forwards, 10 mm downwards, and 10 mm at the side — these are the minimum air gaps to maintain around the contactor for arc flash and creepage compliance.
