Operating times depend on the type of contactor electromagnet and its control mode.
The closing time “C” is measured from the moment the coil supply is switched on to initial contact of the main poles.
The opening time “O” is measured from the moment the coil supply is switched off to the moment the main poles separate.

Note: The arcing time depends on the circuit switched by the poles. For normal 3-phase applications, the arcing time is usually less than 10 ms. The load
is isolated from the supply after a time equal to the sum of the opening time and the arcing time.

The LA6DK mechanical latch blocks cannot be mounted on LC1F contactors, for similar operation use CR1F magnetic latching contactors (see page 226).
