Available from Castell, the KSD+ is a
new trapped key interlock power
isolator suitable for 3-phase currents
from 32 to 250A.

Designed to BS EN 60947-3:2009,
the new KSD+ has been created with
a non-direct drive interlocking
mechanism. The key that controls
the operation of the isolator does not
bear the load of switching the
contacts. Switching is now achieved
with an extending handle that is said
to increase the ease of use, as well as
device reliability. The key traps the
handle in place and prevents
operation when the key is removed.

The ability to switch on the device
while the case is open has been
removed through use of a coded
sensor, which ensures that the case is
secure before allowing operation.

The stainless steel enclosure can
be placed in harsh environments.
