Mounting a sealable shroud
To prevent changes from being made to the overload setting,
you can install a ZB-XPLH/XTOBXCOV sealable shroud
(accessories) and seal it with sealing wire. This will reduce
the risk of tampering and improve operational safety and
reliability.
Overload relays in enclosures or behind covers can be
conveniently operated by using M22-DZ... pushbuttons.
