ABB DSTD108 57160001-ABD Switch input card

To be able to select a suitable line contactor and a suitable power connection fuse protection, the phase current IN at the power connection must first be calculated. The phase currentIN at the power coonnection is determined from the power supplied by the power line SAN . Locate the power connection output in the selection lists of the drive components, or calculate it according to formula Fig. 11-3. For several drive controllers, add the individual power connection output values.

A selection table (Fig. 11-5) is available to facilitate the selection of a suitable line contactor and fuse protector for the power connection.

Selecting the fuse protector Q1 and line contactor K1 

The fuse protector must be rated 1.5 times higher than the actual current at the power connection IN. 

Fuse protection can be implemented using: 

• an automatic circuit breaker (power circuit breaker) or 

• a power circuit breaker or

 • safety fuses.

Select the line contactor according to the phase current 

at the power line and the rated line voltage. The rated current of the line contactor must be 1.5 times higher than the actual phase current at the power line. For a rated line voltage of 3 x 400 V, 50 Hz, , the line contactors listed in the selection table are recommended depending on the phase current IN.

Requirement: The E-stop input is available if the E-stop function in the software is activated (see function description).
