Isolation
Through development and experience Castell has a number of methods to isolate switchgear or machinery. This can be done mechanically, through control circuitry or through power circuitry.
In complex operations a number of isolations may need to occur to ensure that switchgear or machinery is safe to work on.
The isolation keys are then used to either gain direct access, are transferred to a time delay unit or for multiple entry points access through a key exchange box.
