Protection and Connection
OT Non-fusible Disconnect Switches
1600...2000 Amperes
Reliable in extreme
conditions
Suitable for heavy duty applications
at full rated current
OT disconnect switches have a short
circuit rating of 100kA at 600V and
the full general use current ratings at
600Vac and 250Vdc.
Excellent insulation
Reduced risk of arcing between phases
in even the most severe circumstances
and environments.
Space saving Easy to install
Modular design
Flexibility in design allows for space
saving configurations.
Flexible installation
Mounting is possible in any orientation:
horizontal, vertical or even on the
ceiling.
Reduced installation time
For external handles, the shaft is
adjustable at different installation
depths. Key hole mounting feet and
snap-on mounting of auxiliary contacts
make installation easy and fast.
