Reversing bars
A reversing switch can be built by using phase sequence bars in two phases.
The kit includes two phase sequence conversion bars. The missing bridging bars must be ordered separately,
see above. For example 3-pole switches: one 4-pole standard bridging bar kit is required (one bar for the
reversing side, three bars for the other side).
