Reversing
Contactors
Install the interlock unit on
the side of a contactor first.
Fit each part as indicated in
the figure above.
And then install the other
contactor on the other side
of the interlock unit as shown.
After installing interlock unit wiring kit can be assembled.
Wiring kit contains two molded wires - one for line side
and the other for load side.
Reversing contactor consists of:
• Two AC or DC contactors
• Mechanical Interlock
• Wire Set (up to frame size 100A)
