New unit to isolate power

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.
