Product identity and key ratings
The Siemens SIRIUS 3RT1054-6AS36 is a Size S6 power contactor, designed for switching motor loads and resistive loads in industrial control panels. It is fastened via screw fixing and uses screw-type terminals for the magnet coil, with main power connections accepting stranded cable from 25 to 120 mm². Rated for continuous operation in ambient temperatures from -25 to +60 °C, with storage tolerance from -55 to +80 °C. The mounting position allows vertical surface mounting with +/-90° rotation and +/-22.5° tilt forward and back, giving panel builders flexibility in tight enclosures.
Switching performance and duty cycles
Maximum mechanical switching frequency under AC-3 duty is 1 000 operations per hour, matching the AC-3e rating. For AC-1 resistive loads the limit is 800 operations per hour, while AC-4 (plugging / inching) drops to 130 operations per hour. The arcing time is specified at 10 to 15 ms. Coil operating times are 40 to 60 ms for both AC and DC supplies. The auxiliary switch is included as standard.
Dimensions and panel integration
Physical envelope: 120 mm wide, 172 mm tall, 170 mm deep. The contactor mounts via screw fixing, with four 9 mm diameter mounting holes. Minimum clearances around the unit: 10 mm upwards, 10 mm downwards, 20 mm forwards, and 10 mm at the side. These clearances must be maintained for proper arc quenching and heat dissipation.
