Motor switching and coil drive
The Siemens 3RT2016-1JB41-Z W97 is a size S00 power contactor rated for AC-3e/AC-3 duty at 9 A, switching 4 kW at 400 V across three poles. The 24 V DC coil includes an integrated diode, and the coil pickup range is 0.7–1.25 times the rated control supply voltage.
Screw terminals on the S00 frame accept standard control wiring. The contactor is not expandable with an auxiliary switch block — the single 1 NO auxiliary contact is fixed. Multi-unit packaging ships 40 units per pack, which suits panel builders ordering for a production run. The 75 x 57 x 45 mm footprint fits standard DIN-rail enclosures; verify fill factor if grouping multiple contactors in a confined gland plate area.
