This range of contacts is a further development based on our standard version. The construction of the contact finger has been modified with an easy exchange foil package which in cases decreases the size of the unit. Furthermore, guides have been integrated directly in the main module on each side. Besides technical improvements, this also creates an overall less expensive solution as well. These contacts are delivered as a one piece model for bus-bar thickness 10, 15 or 20 mm. Although the installation size of the unit is smaller, parts can still be exchanged according to pages 2 and 3 of this catalogue. Protection against acid and alkaline damage is provided by our A4 protective cover accessory. Protective covers extensively increase the life span of the contacts and minimise expensive repair work as well as down times. All contacts can also be supplied ready to be installed with complete base unit (power connection bar, insulation plate, etc.). It is also possible to produce individual customer specific versions for use in odd-sized or odd formed installation spaces by modifying the standard contact.
