3TC Contactors for Switching DC Voltage

1- and 2-pole, 32 ... 400 A

■ Overview

■ Application

3TC4 and 3TC5

EN 60947-4-1 (VDE 0660 Part 102)

The contactors are finger-safe according to EN 50274.

Terminal covers may have to be fitted onto the connecting bars,

depending on the configuration with other devices.

The contactors are suitable for switching and controlling DC

motors as well as all other DC circuits.

A version with an especially large operating range is available

for use in electrically driven vehicles and in switchgear with

significant fluctuations in the operating voltage (see page 3/74).

The DC motor ratings given in the tables are applicable to the

DC-3 and DC-5 utilization categories with two-pole switching of

the load or with the two conducting paths of the contactor

connected in series.

One contactor conducting path can switch full power up to

220 V. The ratings for higher voltages are available on request.

3TC7

EN 60947-4-1 (VDE 0660 Part 102).

The contactors are suitable for use in any climate. They are

suitable for switching and controlling DC motors as well as all

other DC loads. The electromagnetic excitation is designed for

a particularly wide coil operating range.

It is between 0.7 or 0.8 to 1.2 ™ Us.

3TC74 contactors can be used at up to 750V/400A and 50 Hz in

AC-1 operation.
