2/8 SACE EMA X 2 LOW VOLTAGE AIR CIRCUIT-BRE AKERS

—

SACE Emax 2 derived versions

• Earthing switch with making capacity MTP:
similar to the MT device, this differs due to the
presence of a mechanical stored energy control
which allows the circuit to be opened and
closed. Two versions of this earthing switch are
also available: for earth connection from the up-
per or lower terminals. It can also be acces-
sorized
• with a keylock or padlocks for locking in the
open position.
