Power isolator

The KSD+ from Castell is a new
trapped key interlock power isolator,
suitable for 3-phase currents from 32
to 250A, which is said to
dramatically increase safety
protection over conventional
designs, preventing fail-to-danger.

Designed to the latest BS EN
60947-3:2009 standard, the new
KSD+ has been created with a nondirect
drive interlocking mechanism.

The key that controls the operation of
the isolator does not bear the load of
switching the contacts, traditionally a
potential point of failure. Switching
is now achieved with an extending
handle that enhances the ease of use,
as well as device reliability.
