Siemens 3TC4417-0AG4 2 Pole Industrial Contactor

Siemens 3TC4417-0AG4 is a size 2, two‑pole DC power contactor designed for reliable DC switching with a 32 A main current rating and a 125 V DC coil. It handles DC-3/DC-5 main circuits and includes four auxiliary contacts—two normally open and two normally closed—configured as 22 (2 NO + 2 NC) for signaling and interlocking in control panels. The unit uses screw terminals for both the main contacts and auxiliary circuit, and it is offered in frame size 2 with an IP00 enclosure. Dimensions are approximately 85 mm in height, 70 mm in width, and 145 mm in depth, making it suitable for compact panel installations. Mounting options typically include DIN rail, snap‑on, or threaded mounting to fit a range of enclosure types. With a 125 V DC coil and a rugged construction, it is appropriate for industrial DC control applications such as motor control, process automation, and other dc-powered loads up to 32 A per path.
