KS – Power Electrical Switch
Control Switching
The KS is a key driven electrical switch designed for machine control circuits, and the KS20 is by far the most popular option. This type of isolator should be used for short term, off load isolation. The KS lock is manufactured from either brass or stainless steel. The unit is able to be mounted into an existing panel or for surface mounting within its own polycarbonate IP65 rated enclosure.
OPERATION
The Castell KS powersafe electrical key switch is used for machine isolation in order to protect the hazardous area from access while power is on.
The KS is available for different switching loads as KS20, KS32 or KS63 (20, 32 or 63 amps control isolation respectively).
Please refer to order info on page 6 for more details.
The KS comes with 4 contacts as standard with contacts arrangements as 2NO/2NC or 4NC, but additional sets of contacts are available on request.
The KS is available as a back of panel mount version or as a front of panel mount with an enclosure. Please refer to drawing on page 4 for more details.
APPLICATION
The KS powersafe safety component is used as part of an integrated safety system.
A typical application of KS powersafe electrical switch is machine guarding. It is usually used in combination with an access interlock such as the AI for part body access or an access interlock with an exchange key for full body access control such as AIE.
The KS breaks the machine safety circuit, ensuring a machine is shut down when the key is turned and removed. The key can then be taken to the AI access interlock to enable access to the machine.
