ABB and Boulting power ahead on LV switchgear design

A 100kA LV (low voltage) switchboard, developed by system integrator Boulting for building services and industrial facilities requiring high fault protection, was developed with the help of ABB engineers.

Boulting Technology designed and built the switchboard in the UK before shipping it to Italy where it was ASTA certified to BS EN 61439 – mandatory since November 2014.

Gordon Mullis, managing director at Boulting Technology, says the new system uses natural ventilation to achieve maximum current rating up to 6,300A.

He explains that the design was tested at ABB's laboratory to ensure that temperatures within the assembly remained at acceptable levels.

Additionally, he says that ABB's CB range of air circuit breakers reduces the footprint of the switchgear by 10—20%.

"Boulting's 100kA LV switchboard utilises the latest air circuit breakers from ABB - the innovative SACE Emax 2 range," states Mullis.

" explained Gordon Mullis, "When combined with our innovative turnkey solutions, we're able to deliver designs optimised for maximum cost efficiency without compromising quality or performance."
