Assembly Kits with SENTRON 3VA, 3VL & 3VT MCCBs As described in BS EN 61439-1 & -2 the Forms of Separation comprise
four levels as detailed above.
• Thermomagnetic & electronic protection The various methods of achieving separation can involve sleeving the
• 3 pole & 4 pole busbars inside a separate box or a combination of both methods.
• Plug in & fixed mounted design
• Copper assembly kits Cost Effective Specification

Assembly Kits with Built In Installation Devices In order to gain maximum benefit from the standard it is necessary to
consider the application for which the switchboard is required and the
• Modular spacing - 24 with 600mm cubicle width & 36 with 800mm appropriate level of separation for the environment in which it is to be
cubicle width installed.
For example, a Form 4 switchboard may be appropriate where general
• 150mm or 200mm matrix access is permitted to the switch room.
• Depth-adjustable multi profile busbar (AL 35mm) However, where the switchboard is in a locked substation with access
• Siklip raid wiring system restricted to qualified personnel, a lesser degree of separation may be
more appropriate.
Powerstar 125 Panelboards
Typical Applications
System
Form 1 – No separation
• 250A & 400A panelboard system Typical applications are places where the switchboard is in a secure
• 6,8,12 & 16 125A outgoing ways location and where failure of the switchboard will cause little or no additional
• Fully RoHS compliant disruption to other areas being fed by the switchboard.
• Form 3b type 2 BS 61439-2
• Paint finish, epoxy powder, light grey RAL 7035 Form 2 – Separation of busbars from functional units
• IP3X (door closed) Applications may well be the same as Form 1, but where it is important
• Designed & manufactured in the UK to BS EN 61439-2:2009 that a fault in the switchboard need not affect all functional units being fed
• Integral incoming metering lightning & surge protection from the same busbar system.

Powerstar 250 Form 3 – Separation of busbars from functional units and the
functional units from one another but not their terminations
System Should be applied where it is important to provide protection from internal
live parts and where failure of functional units being fed from the same
• 400A & 630A panelboards busbar would cause unacceptable disruption.
• Main units are available with 2, 4 or 6 outgoing ways suitable for 250A
Form 4 – Separation of busbars from functional units and the
TP MCCBs functional units from one another including their terminations
Should be applied where it is important to provide protection from internal
live parts and where failure of functional units being fed from the same
busbar would cause unacceptable disruption.
Because all the terminations are separated it is possible to isolate and work
on a single functional unit.
