Center Receives Prestigious ASTA

Accreditation

The Cooper Bussmann Paul P. Gubany Center in St.

Louis is certified by Britain’s prestigious ASTA

(Associated Short Circuit Testing Authority) to

perform short testing of its own devices designed to

operate to ASTA requirements which are closely tied

to IEC requirements. The Gubany Center is the only

testing facility available in North or South America

for this product certification.

The Gubany Center has equipment capable of

generating 300,000A of current at 600Vac three-

phase, and 100,000A at 170Vdc, under carefully

controlled conditions. It offers a wider range of

current voltage and frequency configurations than

any other facility of its kind in the world, and is built

to exceed the short circuit capacity of today’s high

power electrical distribution systems.
