The AC-3e rating also caps at 750/h. ## Auxiliary contact ratings and operating conditions This variant ships without an auxiliary switch block, but the main contact ratings at various DC voltages are specified: 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, 3 A at 400 V, and 0.2 A at 440 V. These are the DC-13 (solenoid/electromagnetic load) ratings for the main contacts — useful when switching DC control loads directly.","metaTitle":"Siemens 3RT2016-1CM27 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens 3RT2016-1CM27 SIRIUS power contactor, size S00, 24 VDC coil, screw terminals, 45 mm wide, current production.
