Siemens 3TC4417-0BK6 2-Pole Contactor

Siemens 3TC4417-0BK6 is a frame-size-2, two-pole contactor designed to switch DC-3/DC-5 loads with a 32 A rating. The control coil is rated for 110 V AC (50/60 Hz), with 120 V AC (60 Hz) variants available by region, enabling straightforward control from standard automation circuitry. It includes two normally open and two normally closed auxiliary contacts (2 NO + 2 NC) in a 22 configuration for feedback, signaling, or interlock functions. Wiring uses screw terminals for both the main contacts and the coil, supporting secure field connections. This model is part of Siemens' DC-contactor line and is suitable for motor-control and other DC-load applications in industrial equipment, where compact footprint and reliable switching are important. With its DC-3/DC-5 designation, it is intended for controlled DC voltage circuits and can be integrated with Siemens accessories and enclosures that support 3TC-series contactors. The 3TC4417-0BK6's frame size and current rating make it a practical choice for replacing older DC contactors of similar footprint while maintaining the 2-pole design and the dual auxiliary contact block.
