The breadth of the CT contactor range satisfies most
application cases (multi-pole, pole composition,
etc.). CT contactors can be combined with auxiliary
control, protection and indication functions.

Operation
CT contactors equipped with one or more normally open (NO) or normally closed
(NC) contacts are controlled by latched type electrical orders. On the front face a
red indicator light indicates voltage presence at the coil terminals (A1-A2).
Manually-operated contactors have a 4-position selector switch on their front face:
