DISCONNECT
CUS
CUS
35 or 32mm DIN Rail
Disconnect and test terminals are
an ideal choice for measuring control and regulatory circuits.The terminals provide a clear functional
advantage for devices having utility instruments and associated
transformers.
Five versions of disconnect and
test terminals are available:
• CDTTU - disconnection is
achieved by means of a slide
link operated with a screw driver.
• CDTTU-SH - disconnect and test
terminals are ideal for use in
current transformer applications
when it is mandatory to keep the
secondary side shorted at any
point while taking current
measurements.
• CKT4U - disconnection is
achieved by lifting the
knife contact lever.

and testing terminal,
incorporates a connecting link in
place of the fuse link.
• CSDL6U - hinged disconnect
block for 8 AWG size wires.
• DDDL4U - double level
disconnect terminal with hinged
disconnect in upper level.
Specially designed socket head
screws act as test/monitoring
points in both CDTTU, CDTTU-SH
and CKT4U.
Important: The disconnecting
device is not suitable for interrupting load.The supply must be
switched off before operating the
slide link/lever.
