SIRIUS S6 power contactor with 24 VDC coil
The Siemens 3RT1054-2XB46-0LA2 is a SIRIUS S6 power contactor with a 24 VDC coil, screw fixing, and an integrated auxiliary switch. It is rated for the S6 frame size, which determines its footprint and mounting hole pattern for panel integration. The coil draws 6 A at 24 V rated value, with a pickup dropout characteristic typical of DC-operated contactors — the arcing time is 10 to 15 ms and the closing time at DC is 80 to 90 ms. Mechanical switching rates vary by duty: up to 1 000 cycles per hour in AC-3 and AC-3e, 800 in AC-1, 400 in AC-2, and 130 in AC-4. For DC loads, the rates are 400 in DC-1 and 500 in DC-3 and DC-5.
Auxiliary contact DC ratings and terminal details
The auxiliary switch is rated for DC switching at specific voltages: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, and 0.9 A at 125 V. These ratings define the maximum continuous current the auxiliary contacts can break under DC inductive loads. Screw terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire. The mounting uses screw fixing with a 9 mm hole diameter, and the contactor can be rotated ±90° or tilted ±22.5° on a vertical surface.
Environmental range and clearances
Operating temperature spans -40 to +70 °C; storage range is -55 to +80 °C. Minimum clearances for arc containment: 10 mm upwards, 20 mm forwards, 10 mm downwards, and 10 mm at the side. Dimensions are 172 mm height, 120 mm width, and 170 mm depth — the S6 frame size fits standard panel layouts with screw-fixing compatibility.
