Delivery program
Basic function   Locking arrangements
Function   Key operation lock mechanism
   KABA lock 90 Grad
When ordering with basic unit
For use with   Centre mounting (EZ)
Information about equipment supplied   with two keys
Key withdrawable with  
Degree of Protection   IP65
Notes The KABA lock for 90° can be used for other switching angles as well (for example) if the key withdrawability characteristics match the switch.
Example: +EZ/S-B can be used with a step switch with a switching angle of 30° if the key should only be withdrawable in the 0 position at 270°.
