Rolla 100kA Distribution Switchboard (DSB)

Continuously rated up to 6300A, IP31 naturally ventilated switchboard certified for a fault level of 100kA for 1 second or 80kA for 1 second and temperature rise tested to the latest standard BS EN 61439-2:2011 (IEC 61439-2:2011).

This switchboard incorporates the complete range of innovative ABB Emax 2 ACB's in a surprisingly compact type tested (design verified) layout. The E6.2 is fully rated at 6300A and fits in a 1300mm wide section, whilst the E4.2 is fully rated at 4000A and fits in a 900mm wide section. This is without the need for any derating or forced ventilation and with the main busbar system at the bottom of the board, the most onerous condition.
