The KSE is a multi-key controlled electrical switch suitable for the isolation or switching of 20, 32, 63 or 150 amp (maximum) current.This type of isolator should be used for short term, off load isolation and operated by suitably qualified personnel. The unit is supplied for mounting into an existing panel or for surface mounting within its own IP65 rated lockable steel enclosure. It is available in FS or Q type lock portions. The KSE is manufactured from either brass or stainless steel making it ideal for use in standard or harsh corrosive environments.
A typical application of KSE powersafe electrical switch is machine guarding. It is usually used in combination with an access interlock such as the Salus for part body access or an access interlock with an exchange key for full body access control such as AIE.
A typical system will isolate machinery and control access to hazardous areas. Removing the power isolation key from the KSE unit changes the condition of the electrical supply to the machine to a safe condition and enables the release of the secondary keys. These keys are then used to unlock the AIE dual key access interlocks.
The guards can only be opened when the electrical supply has been switched into a safe condition and only once all the keys have been returned to the KSE interlock can the machine be restarted.
