The new protection releases integrate all the functions their predecessors, adding new and interesting technical features that are useful for
satisfying every current and future system installation need.
Notes:
1. Protection releases General notes
The Emax series ABB air circuit-breakers now has new range electronic releases for applications called PR122/DC and PR123/DC.Pocket S
Compatibility with SD.
Every operational requirement now met thanks the different performance levels the new relays and the additional odules that can
be fitted inside them (PR120/V, PR120/LV, PR120/K, PR120/D-M, PR120/D-BT).
