The DC coil means it holds in without AC hum and drops out cleanly on DC control circuits — relevant if your panel runs a 110 VDC control bus from a battery-backed supply or rectified rail. ## Switching duty and operating rates Maximum switching rates vary by duty class: 1 000 operations per hour in AC-3 and AC-3e, 800/h in AC-1, 400/h in AC-2 and DC-1, 500/h in DC-3 and DC-5, and 130/h in AC-4. The AC-4 rate is the limiting factor for plugging or inching duty — if your application requires frequent reversing or jogging, the 130/h ceiling governs the cycle budget. ## Panel fit and mounting flexibility Screw fixing is the standard fastening method. Overall dimensions are 172 mm height, 120 mm width, 170 mm depth. ## Wiring terminals and conductor range The single 9 mm diameter mounting hole is sized for M8 hardware. ## Auxiliary contact DC ratings and arcing time The auxiliary switch is rated 6 A at 24 VDC, 2 A at 48 VDC, and 2 A at 60 VDC. The dropout time on DC is 80 to 90 ms, which is the interval the load sees before the main contacts open. ## Environmental limits and mechanical endurance Typical mechanical life is 10 000 000 operations. The full-scale value for the thermal overload relay setting range is 1.25, with an initial value of 0.7 — these are the adjustment limits on the matching overload relay.","metaTitle":"Siemens 3RT1054-1XF46-0LA2 SIRIUS Contactor, 110 VDC Coil","metaDescription":"Siemens SIRIUS contactor 3RT1054-1XF46-0LA2, Size S6, 6 main contacts, 110 VDC coil.
