3.4.7.7 Sealing cover (3RT19 .6-4MA10)
With the use of contactors and control relays in safety related applications, it
must to be made certain that the manual activation of the contactor isn’t
possible.
For applications of this kind there is a sealing cover available as an accessory
that prevents unintentional manual activation. It is a see-through moulded
plastic cap with a clip that makes sealing the cover possible.
