disconnects or as manual motor disconnect
switches. They provide an economical

power on-off switches or starting and
stopping of motors. These switches are
switches only and do not replace the need for
fuses or circuit breakers.
They are typically installed inside of an
enclosure and can be mounted directly to
the back panel on DIN rail and used as an
internal switch. They can also be used as an
external switch, mounting accessories are
available for panel mounting or mounting
with an extended door interlock handle.
