That depth is the dimension you'll need to check against your enclosure back-panel clearance — especially if you're retrofitting into an older cabinet where the gland plate or door-mounted components eat into that space. Mounting is screw-fix, not DIN rail, so budget for drilling and tapping the backplate. The contactor can be mounted on a vertical surface and rotated ±90°, or tilted ±22.5° forward/backward, which gives you some play when aligning with busbars or existing wiring troughs. ## Auxiliary Contact Loads Comes with an auxiliary switch block built in. The DC ratings on the aux contacts are what matter for PLC or relay interface circuits: 6 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V. If you're switching a 24 VDC relay coil or a small solenoid valve, the 6 A figure gives comfortable headroom. Don't push the 125 V/0.9 A line too close to the limit — inductive loads will arc longer than the 10–15 ms arcing time suggests. ## Operating Cadence Switching frequency varies by duty class: 1 000 ops/hour under AC-3 (motor starting), 800 under AC-1 (resistive), 400 under AC-2, and 130 under AC-4 (plugging/inching). For DC loads, 500 ops/hour under DC-3 and DC-5, 400 under DC-1. If you're running a high-cycle pick-and-place or a conveyor that jogs frequently, the AC-4 limit of 130 ops/hour is the binding constraint — don't spec this for a rapid-reversing application without checking the thermal curve.","metaTitle":"Siemens 3RT1054-2XJ46-0LA2 SIRIUS Contactor, Size S6, 170 mm","metaDescription":"Siemens SIRIUS 3RT1054-2XJ46-0LA2 contactor, Size S6, 170 mm depth, 120 mm width.
