Terminal cover

Function

Terminal covers are used as touch protection for the MTSE with flat terminal.
If additional touch protection is required for the terminals (e.g. IP20 degree of protection from

the front), terminal covers can be used instead of phase barriers.
Phase barriers and terminal covers cannot be connected simultaneously.

Sizes and article numbers

The optionally available terminal covers are listed in the table below.
