Note:-
Standard SAK terminal blocks can also be mounted on the TS32 assembly rail for the
+VE terminations.
We suggest:-
SAKR for disconnect connections (cross connect, using the required length of QB 25
013400, as necessary).
SAK 2.5 for feed-through connections (cross connect using the required length of
QL as necessary).
