The AC-3e maximum is also 750 cycles/hour. ## Wiring and environmental limits The main contact wire range is 20 to 12 AWG. The contactor has no built-in auxiliary switch — plan for an external auxiliary contact block if needed.","metaTitle":"Siemens 3RT2016-1JB42-1AA0 SIRIUS Contactor, 24 VDC Coil","metaDescription":"Siemens 3RT2016-1JB42-1AA0 SIRIUS coupling contactor, size S00, 24 VDC coil rated 10 A.
