The AC-3 switching frequency of 750 operations per hour matches typical cyclic machine loads. For AC-1 loads, the contactor handles 1,000 operations per hour; for AC-4 duty, 250 cycles per hour. The ring cable lug connection on the magnet coil is the termination style — verify your control wiring matches before terminating. These are the minimum air gaps to adjacent metalwork or other devices for proper heat dissipation and arc containment. The 27 A at 480 V 60 Hz is the thermal current rating at that specific voltage and frequency. For a 60 Hz system in North America, this contactor directly handles a 480 V motor load up to that current. At 50 Hz, the coil rated voltage shifts to 200 V — the contactor is frequency-sensitive, so don't assume 50/60 Hz interchangeability without checking the coil spec. No separate add-on block needed for basic N.O./N.C. signaling.","metaTitle":"Siemens 3RT2027-4AN60 SIRIUS Power Contactor, S0 Size, 27 A","metaDescription":"Siemens 3RT2027-4AN60 SIRIUS power contactor, S0 size, 45 mm wide, 27 A at 480 V 60 Hz.
