Schneider Electric’s distribution and motor control switchboard

March 2015 Electrical Power & Protection

Blokset, Schneider Electric’s modular low voltage switchboard for electrical distribution up to 6300 A and for motor control, fully withdrawable up to 250 kW, is now available in the southern African region. It follows a global design and is type tested and certified according to IEC61439-1 and IEC61439-2, guaranteeing the safety of both the installation and the operator.

“Blokset has become the reference switchboard for a large number of panel-builders, industrial site managers and maintenance managers. One of the main reasons for this is that the distribution and motor control switchboard comes with the certainty of rapid return on investment, and the switchboards have long guaranteed the durability and availability of several tens of thousands of installations worldwide,” says Ernie Smith, vice president: low voltage division at Schneider Electric.

He adds that Blokset technology has never ceased to satisfy end-users in their search for optimised solutions for better, faster and more economic production, and panel-builders in their search for equipment that is more reliable and easier to install and maintain.

“In a constantly changing industrial and economic world, you need to be able to upgrade your installations at all times to remain competitive. This modular switchboard concept is able to overcome these challenges,” he says.

Both green and safe, all the components of a Blokset switchboard are designed and produced by Schneider Electric. Blokset incorporates state-of-the-art Schneider Electric components, such as conventional and intelligent motor control centres (MCC/iMCC), variable speed drives and soft-starters. As such, it offers a unique global design with local implementation, allowing flexibility in project management, adaptability to local project habits and end-user needs.

“A great advantage is that it is manufactured close to the end-user exclusively by Schneider Electric or Schneider Electric licensed partners. This guarantees the best delivered quality,” says Smith.

Referencing to the earthquake in 2014 around Orkney in South Africa, Smith highlights that Blokset offers an extremely high level of reliability even in the most difficult conditions. “Blokset offers internal arc withstand in accordance to IEC 61641, earthquake and seismic zones withstand, as well as corrosive ambient protection making it ideal for mining applications,” he adds.

Blokset applications are best suited for medium and large industrial sites, including mining, oil and gas, pulp and paper, manufacturing and metal processing. It is also suited for medium/ large commercial and building areas such as shopping malls and hotels, as well as infrastructures, including water treatment, airports, harbours and local electrical distribution where reliability, energy efficiency and safety is of the highest importance
