The AC-3e rating also holds at 750/h. For DC switching, the contactor is rated at 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V — these are the values that govern fit for a DC load circuit, not the AC motor rating. ## Thermal limits and mechanical endurance The contactor is rated for 10 000 000 mechanical operations typical. Arcing time is 10 to 10 ms. The coil hold-in range is 0.8 to 1.1 times the rated value (24 V). ## Dimensions, clearances, and wiring Width 45 mm, height 85 mm, depth 151 mm. Accepts solid or stranded conductors from 1 to 10 mm² on the main contacts, and 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) for auxiliary circuits. No auxiliary switch is fitted as standard.","metaTitle":"Siemens 3RT2027-1FB48-0ME2-ZX95 SIRIUS Power Contactor, S0,","metaDescription":"Siemens SIRIUS 3RT2027-1FB48-0ME2-ZX95 power contactor, Size S0, 24 VDC coil, screw terminals.
