In BlokSeT Mw2 (common) neutral vertical bars, why this solution is only provided for rear access column? Is it possible to use it for front access with Form 3b?

Hur kan vi hjälpa dig idag?

When we include the neutral earth bars inside the Mw2 cable compartment, then the Neutral bus bar will be directly connected to the Main bus bars. As per the form definition it cannot be form 3b even though the functional unit terminals are separated from the main bus bars. As neutral bar is considered as live conductor. Mw2 rear connection will also become Form 1 with neutral bar in cable compartment.

So with neutral earth bar with present architect, it is not possible to offer form 3b to customer. To have form 3b, then neutral bar should be isolated. We do not have solution. For any further information, please contact L3 technical support team.
