Schneider Electric Easy9+ - Din Rail Mount Blanking Pole for EZ9+ Circuit Breaker Consumer Units, EZ9EBP (Pack of 5)

As described, works as intended

There's some cheapo generic Chinese busbar for sale on here which is far too lightweight to cope with its potential loads and frankly could be dangerous.This one is the one you want; heavy duty and well worth the money.

Solid full copper busbar with the only offset that allows a neutral feed to access a DPST contact breaker as shown aboveAs someone said it REALLY needs an isolating sheath for when the enclosure doesn't have a protector hence only 4 stars :-(I'm sure a hot dip insulation would do the trick at minimal cost.

Could do with a insulation strip. Expensive for what it is

Gives a nice finish to the fuse board but way too expensive
