Siemens 3TC4417-0B DC Contactor 32A Open Three Pole

Siemens 3TC4417-0B is a 32 A DC contactor in the Siemens 3TC family, configured as a frame size 2 device with two main contacts and four auxiliary contacts (2 NO + 2 NC). It is available with multiple coil-voltage options, including 24 V DC, 120 V AC, 230 V AC, and 300 V DC, as shown in Siemens datasheets for variants in the 3TC4417-0B line. The contactor is rated to switch DC loads up to 600 V and uses screw-terminal connections for the main and auxiliary circuits. Typical applications include DC motor control, DC power-distribution tasks, battery charging/discharging, and other automation tasks requiring a 32 A switching device. In Siemens Industry Mall listings, variants such as 3TC4417-0BS0, 3TC4417-0BL2, and 3TC4417-0AB4 demonstrate coil-voltage diversity while preserving the 32 A, 2-pole, 2 NO + 2 NC configuration. This product supports standard DIN-rail or panel-mount layouts consistent with frame size 2 contactors in the 3TC family.
