SIRIUS S6 power contactor — DC coil, auxiliary contacts onboard
The 3RT1054-6XJ46-0LA2: Rated for 6 A at 24 V DC on the auxiliary circuit, the contactor also handles 2 A at 48 V DC, 2 A at 60 V DC, 1 A at 110 V DC, and 0.9 A at 125 V DC — covering control voltages common across European and North American panels. Mechanical life is rated at 10,000,000 operations typical, which aligns with the SIRIUS S6 platform's design for high-cycle applications like conveyor lines or pump stations. Operating temperature range is -40 to +70 °C during operation, with storage from -55 to +80 °C, making it suitable for unheated enclosures in temperate climates.
Switching frequency and duty cycle ratings
Maximum switching frequency varies by duty class: 800 operations/hour in AC-1 (resistive loads), 400/h in AC-2 (slip-ring motors), 1,000/h in AC-3 (squirrel-cage motors — the most common motor-starting category), and 130/h in AC-4 (plugging/reversing). DC switching frequencies: 400/h for DC-1 (resistive), 500/h for DC-3 (shunt motors), and 500/h for DC-5 (series motors). AC-3e rating matches AC-3 at 1,000/h. Arcing time is 10 to 15 ms, and the DC operating time (coil pull-in/drop-out) is 80 to 90 ms — useful for sequencing logic in timed interlock circuits.
Mounting and clearances
Fastening is screw fixing (not DIN rail), with a single 9 mm mounting hole. The contactor measures 172 mm high, 120 mm wide, and 170 mm deep — the S6 frame is a substantial footprint that needs planning in the panel layout. Mounting position is flexible: vertical surface with ±90° rotation and ±22.5° tilt forward/backward. Minimum clearances: 10 mm upwards, 20 mm forwards, 10 mm downwards, and 10 mm at the sides. Terminal capacity accepts solid or stranded conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and up to 2x 0.75 to 4 mm² — covers standard control wiring in both metric and AWG equivalents.
