Product design which pursues greater use ease by wide variations
Interchangeable Relay Unit
To enhance flexibility, the Mitsubishi
WS Series is equipped with
interchangeable relay units (available
in thermal or electronic types).
The move has been made to
AC/DC common use, while the
expanded adjustment range enables
reduction in the number of 250AF
relays from 10 to 7 types.
A magnetic adjustable function has
been added to the thermal type,
while 4P neutral protection has also
been enhanced.

available to replace)
