Caution Precaution for Correct Use
・When the Magnetic Contactors are switched rapidly, use an
electrically interlock, such as a delay relay, to ensure a switching
time of at least 15ms for the contacts of the two Magnetic
Contactors.
Mechanical Interlock Unit
Interlock Unit
(1) Connect two Magnetic Contactors with the two connection
pieces ①.
(2) Move the moveable projections ② on the Interlock Unit to the
right side.
(3) Insert the Interlock Unit directly from the top so that it is aligned
with the projections ③ on the moveable portion on the Magnetic
Contactors.
(4) After you mount the Interlock Unit, slide the projection on the
indicator window on the right side and then on the left side to
confirm that they move smoothly.
Power Connection Kit for Reversing
Connect the Kit to the main circuit terminals. There are wires for the
power supply side and wires for the load side. Be sure to connect
them to the correct sides.

Mechanical Interlock Unit and Power Connection Kit for Reversing
Features
Mechanically prevent two Magnetic Contactors from turning ON at
the same time.
Combine a Reversing Connection Kit with an Interlock Unit to easily
configure a reversing Magnetic Contactors.
Mounting two Magnetic Contactors on the front surface reduces the
mounting footprint and contributes to downsizing control panels.
