The Siemens 3RT1016-1BF45-ZW96 is a 3-pole contactor from the SIRIUS series, Size S00, with a DC 110 V coil and an auxiliary contactor block mounted on the front carrying 3 normally-open and 2 normally-closed contacts.
The front-mounted auxiliary contactor block adds no extra DIN width — it stacks vertically, so the panel layout stays compact. Screw terminals are standard for panel builders who prefer a positive mechanical clamp over spring-cage; strip length and torque follow the manufacturer's published values.
