That 10 A at 24 VDC switching rating tells you it handles DC control circuits and small DC motors; the 7.6 A at 480 V and 9 A at 600 V cover common North American motor voltages for smaller three-phase loads. Mechanical life is typical 30 million operations. At AC-3 duty (standard motor switching) it's rated 750 operations per hour; at AC-4 (inching/plugging) that drops to 250 per hour. The arcing time of 10–15 ms and DC operate time of 7–13 ms are what you'd expect for a contactor this size — fast enough for most sequencing but not a high-speed DC switch. That lets you pack S00 contactors on a DIN rail with minimal gap, but verify the arc flash boundary if you're grouping them without barriers. Coil connection is ring cable lug — not a spring-cage or screw-clamp terminal. Factor in the lug crimp tool and ring terminal size when wiring the panel; it's a solid connection but slower to terminate than push-in types.","metaTitle":"Siemens 3RT2016-4BB42 SIRIUS S00 Power Contactor, 24 VDC Coi","metaDescription":"Siemens 3RT2016-4BB42 SIRIUS S00 power contactor, 24 VDC coil, 45 mm width, screw and snap-on DIN rail mount.
