5%) and numerous other functions. Protection releases General notes
Emax, the range ABB air circuit-breakers, now has new range electronic relays.
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. Wireless Bluetooth connection PDA and/or (with PR120/D-BT BT030).
4. Date and tim "real tim (all relays).
16. High-performance data logger with analogue signals and digital signals, which can synchronized with hundreds events/situations
of the user's choice.
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/K, PR120/D-M, PR120/D-BT).

The main features and improvements the new relay PR12x with respect the earlier PR11x are (depending the combination relay-
modules):
1. Input can combined with actions selectable the user (with PR120/K). Extended neutral selection. with separate BT030 unit (for tem porary connections),
