The contactor measures 214 mm high, 160 mm wide, and 225 mm deep. These clearances must be maintained for arc-flash containment and cooling. Auxiliary wiring accepts solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) — typical for control-circuit terminations. ## Switching performance and duty ratings Maximum switching frequency varies by duty: 700 operations per hour in AC-1 (resistive), 500/h in AC-3 (motor start/run), 200/h in AC-2, and 130/h in AC-4 (plugging/inching). AC-3e matches AC-3 at 500/h. Arcing time is 10-15 ms. Mechanical life is typically 10,000,000 operations. Auxiliary contact ratings: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V — these are the switching capacities for the built-in auxiliary contacts.","metaTitle":"Siemens 3RT1075-6NF36 SIRIUS Power Contactor, 96-127VAC Coil","metaDescription":"Siemens SIRIUS 3RT1075-6NF36 power contactor, size S12. 96-127 V AC coil, screw terminals.
