Side-by-side mounting is permitted, so panel fill factor is straightforward — the 55 mm width per unit is the only horizontal space needed. ## Ratings and switching capability For AC-3 duty (motor switching), the maximum operating voltage is 690 V, and the contactor can handle up to 800 switching operations per hour at AC-3, or 250 per hour at AC-4 (plugging/inching).","metaTitle":"Siemens 3RT7026-1AH05 SIRIUS Contactor, 3-pole AC-3, 55 mm w","metaDescription":"Siemens 3RT7026-1AH05 SIRIUS S0 contactor, 3-pole, AC control, screw terminals, IP20.
