General
The arc switching on d.c. is more difcult than on a.c.
• For selecting a contactor it is essential to determine the current, the voltage and the L/R time constant of the controlled load.
• For information, typical time constant values are quoted hereafter: non-inductive loads such as resistance furnaces (L/R ~ 1 ms), inductive loads such as shunt motors
(L/R ~ 2 ms) or series motors (L/R ~ 7.5 ms).
• The addition of a resistor in parallel with an inductive winding helps in the elimination of the arcs.
• All the poles required for breaking must be connected in series between the load and the source polarity not linked to earth (or chassis).

Technical Data
• The tables indicate for the standard contactors the Ie max. operating currents depending on: the utilization category (i.e. L/R) DC-1, DC-3, DC-5 as dened in the IEC
60947-4-1 publication, the operating voltage Ue and the pole coupling details. See page 1.81.
Ampere values quoted in the tables below are valid for a -25 … +70 °C temperature close to the contactors, as long as the AC-1 Ampere values (see pages 1.45 - 146)
for the corresponding ambient temperature are not exceeded.
• Max. switching frequency: 300 ops/h.
• For switching higher d.c. ratings, we recommend the use of bar mounted contactors, R series (63 … 2000 A).
The selection table for AE 50 ... AE 110 contactors can be used for the TAE 50 ... TAE 110 types.
