Not only is this a first for ACDC Dynamics it is first for Africa. Our OEM supplier Terasaki have the ONLY type tested Certified Air Circuit Breaker retrofit in the world. Terasaki TemPower 2 Air Circuit Breaker is the result of an intensive market research program which took into account the requirements of switchboard builders, consultants and end users.

ACDC have replaced three old breakers in the Rustenburg mining belt. These breakers where type tested with their enclosure, meaning that should the breakers be updated the bus bars would have to be changed to accommodate the new circuit breaker design. According to the Department of Mining safety standards, a type tested MCC or Distribution board is a requirement by law. For this Rustenburg mine The changing of the bus bars would result in the enclosure losing its type tested certificate and would have meant that the Motor Management Center would have to be disconnected and sent to foreign laboratories to be re-type tested.

Terasakis’s innovative solution meant that the mine could upgrade their existing board with the latest technology and communication, without changing the connecting busbars. Terasaki has developed a solution for every ACB manufactured in their database. These “kits” are assembled onto Terasaki ACB’s and then tested both in house and by third party laboratories. The TemPower 2 ACB is extremely reliable in service with more rated electrical and mechanical operations than their competitors. Using this retrofit solution the MCC retained its type tested certification. ACDC was successful in supplying and commissioning the first Type Tested Retrofit Solution in Africa while adhering to safety standards, minimizing cost and downtime.
