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.
