- The new 22.5mm is close to identical to the profile of the 17.5mm Chronos 2:
- Same position of terminal blocks for a perfect alignment between the 17.5mm and 22.5mm timer versions.
- Same appearance in design than the 17.5mm versions.
-
- = A 45mm “nose height” on the front of the product to allow the mounting of the 22.5mm versions in modular panels.
- Slightly longer than the 17.5mm versions to allow the 2 relays SPDT 8A / 250VAC.
