Three and four-level terminal blocks
with PE foot SLKK... and DLK...
Notes:
1
) The voltage is determined by the LED display (only for SLKK 5-
LA...)
Three-level terminal blocks SLKK5...
– With two laterally offset feed-through
levels and ground connection to the DIN
rail which acts as a grounding busbar
– This allows space-saving and systematic
wiring of 3-wire conductors
– This is of advantage for controllers with
external actuators, solenoid valves, and
limit switches
– The SLKK5-LA...U-O with integrated
LED display visually indicates the voltage
condition of the lower feed-through level
– The FBI10-6 fixed bridge is used on the
upper level to connect the return lines for
the LED displays and the external loads to
form a common busbar
Four-level terminal blocks DLK...
– The three-conductor terminal blocks
DLK2,5-PE and DLKB2,5-PE are
particularly suited to wiring three-phase
current loads due to their structure with
three feed-through levels plus a PE
connection
– To reduce the amount of wire used, the
DLKB2,5-PE can also be bridged in the
middle and lower levels using the
insertion bridges EB...DIK with up to
