Underground Portable Power Centres

Find Littelfuse Startco Capabilities

IMPORTANT NOTICE: New changes to code CAN/CSA-C802.2-12 will require transformers to be more efficient. Once in effect, these changes will require transformers to have heavier coils and cores, resulting in the overall dimensions of the transformer to be larger. The new transformers may or may not fit in your existing fleet of Littelfuse Startco mine power centres. It is recommended to purchase spare transformers from Littelfuse Startco before the code comes into effect in mid 2018. For more information on this pending standard change and how it will affect your mine power centres please contact Littelfuse Startco.
