The contactor uses spring-loaded terminals for both the main current circuit and the auxiliary/control circuit, which speeds wiring and reduces the risk of loose connections under vibration. The coil pickup voltage is 0.85 x rated value (20.4 V), and dropout is 1.1 x rated value (26.4 V). Holding power at DC is 3.3 W, so the coil stays cool in continuous duty. Its footprint is 45 mm wide, 60 mm high, and 73 mm deep. ## Switching capacity and coordination At AC-4 (inching/plugging duty) at 400 V, the rated operational current is 8.5 A. For type of coordination 2 (no welding after a short circuit), the required backup fuse is gL/gG 20 A; for type 1 (welding permitted), use a 35 A gL/gG fuse.","metaTitle":"Siemens 3RT1016-2BB41 SIRIUS Power Contactor, 24 VDC Coil, 1","metaDescription":"Siemens 3RT1016-2BB41 SIRIUS power contactor, size S00. 24 VDC coil, 10 A rated operational current at AC-12.
