Siemens 3TC4417-0A DC Contactor 2 Pole 600VDC 32A

Siemens 3TC4417-0A is a two-pole DC contactor in the SIRIUS 3TC family rated to switch up to 600 V DC at 32 A. It is built in frame size 2 with screw-terminal connections and includes two auxiliary contacts (2 NO + 2 NC) for signaling or interlocking. Designed for DC-3/DC-5 load classes, it supports DC operation and is commonly used to switch medium‑voltage DC circuits in motor drives, battery systems, and DC power-distribution applications. The 3TC4417 family comprises variants with different coil voltages; for example, 3TC4417-0AB4 uses a 24 V DC coil, while other variants such as 3TC4417-0AW4 use 48 V DC, enabling selection to match control electronics. Mounting options include snap-on TH 35 DIN rails or screw mounting in control cabinets, reflecting Siemens’ DIN-rail‑compatible design ethos. This model’s combination of 32 A ratings, 600 V DC capability, two-pole configuration, and 2 NO + 2 NC auxiliary contacts makes it suitable for implementing DC switching with straightforward status feedback in industrial power electronics without exceeding the rated load characteristics.
