Specifications

Type 3TC general purpose contactors

meet or exceed the requirements

of NEMA, UL, CSA, IEC, VDE and other

international standards. Information on

approvals in Section 1.Application

Type 3TC DC contactors are primarily

used in mining, steel mills, and other

heavy duty industrial applications.These contactors are designed for

continuous operation and they are used

to remotely control DC drives, cranes,

hoists, heaters and lamps as well as

such apparatus as battery-chargers,plating equipment and transit systems.

These contactors can be used for

starting of DC motors where the

starting current does not exceed 10

times the current corresponding to

the horsepower rating of the contactor.

The ratings given in the Contactor

Ratings Table apply for the double-pole

switching of loads or when the two

contact paths of the contactor are

connected in series. When only onecontact is used, the values given can

be switched at voltages up to 220V.

Mounting

The contactors must be mounted in theposition indicated in drawing.

Contactors can be tilted up to 22.5 off

the vertical.
