Product Description

Reversing Contactor, DC-3/DC-5, 32 A, 2-Pole, 110 V DC – 3TC4417-4AF4

The Siemens 3TC4417-4AF4 is a robust reversing DC contactor assembly designed for reliable switching, forward/reverse control, and safe operation of DC motors and DC loads in industrial applications. Built for DC-3 and DC-5 utilization categories, it ensures dependable performance in both inductive and resistive DC switching duties with high electrical endurance.

This model is a 2-pole, 32 A reversing contactor configuration with a 110 V DC coil, typically used in applications where controlled direction change of DC motors or polarity reversal of DC circuits is required. The reversing arrangement is achieved through an internal mechanical/electrical interlocking system that prevents simultaneous operation of forward and reverse contactors, ensuring safe operation and protection of the system.

The 3TC4417-4AF4 is widely used in industrial automation, DC motor reversing systems, battery systems, traction applications, conveyor systems, and specialized DC drive control panels where reliable direction control is essential.
