The Siemens 3RT1016-1BM45-ZW96 is a 3-pole contactor in the SIRIUS series, size S00, with a DC 220 V coil and a front-mounted auxiliary switch block carrying 3 normally-open and 2 normally-closed contacts. The screw terminals accept standard ferrule or solid conductors for panel wiring.
Deployment context
The DC 220 V coil allows direct connection to a DC bus or rectified supply without an AC-to-DC interface module — a common requirement in installations where the control voltage is derived from a battery-backed DC system.
