The 45 mm wide, 58 mm high, 117 mm deep footprint fits standard S00 contactor spacing. Main and coil terminals accept solid or stranded wire: 0.5 to 4 mm² single, or 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm². No auxiliary switch block is included on this variant. ## Switching performance and mechanical life Maximum switching frequency varies by duty: 1,000 cycles/h for AC-1 resistive loads, 750 cycles/h for AC-2 and AC-3 motor starting, 250 cycles/h for AC-4 plugging/reversing, and 750 cycles/h for AC-3e. Arcing time spans 10 to 15 ms at AC; the contactor's opening time is 4 to 15 ms at AC. The 24 VDC coil draws 0.25 A at both 50 Hz and 60 Hz. ## Breaking capacity for DC control loads Rated breaking capacity at 24 VDC is 6 A, at 48 VDC is 2 A, at 60 VDC is 2 A, at 110 VDC is 1 A, at 125 VDC is 0.9 A, at 220 VDC is 0.3 A, and at 440 VDC is 0.2 A. At 400 VDC it breaks 3 A. The 230 VAC rating is 1 hp, confirming motor-switching capability at that voltage level.","metaTitle":"Siemens 3RT2016-1CN27 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens 3RT2016-1CN27 SIRIUS power contactor, Size S00, 24 VDC coil, screw terminals.
