Type

Indication

Impulse/latched control

With Open/Close auxiliary contact

● This auxiliary allows indication of the”open” or”closed”position of the contactor power contacts

● This auxiliary, combined with contactors, enables them to be controlled by

2 order types:

● impulse order for local control(input T)

● latched order for centralised control (input X)

● the last order received takes priority

Wiring diagrams
