3TC4417-0AB4

The contactor model 3TC4417-0AB4 offered by Siemens in the SIRIUS series is engineered for reliable switching applications. It operates effectively at an insulation voltage rated value of 800 V. The unit is equipped with a maximum allowable voltage for protective separation of 300 V, guaranteeing safety between the coil and the main contacts during usage.

In terms of performance, the contractor exhibits shock resistance capability with ratings of 7.5g over 5 ms and 3.4g over 10 ms, enabling it to withstand various mechanical stresses. Weighing in at 1.06 kg, it is compact and easy to handle. The device is designed with two poles and is suitable for environments with a minimum relative humidity of 10%.

Mounting this contactor is straightforward, as it can be attached to a 35 mm DIN rail using both screw and snap-on methods. Its footprint measures 85 mm in height, 70 mm in width, and 145 mm in depth, making it easily integrable with existing control panels.

The contactor features a 24 V control supply voltage at its rated DC value and provides closing and holding power for the magnet coil rated at 10 W. The electrical connection type is a screw terminal, ensuring secure connections. Timing specifications reveal a closing delay of 35 to 190 ms and an opening delay of 20 to 30 ms, with an arcing time of 20 to 30 ms, thereby enhancing its operational efficiency.
