The US High Voltage and Medium Voltage Circuit Breaker OEM market accounts for roughly two-thirds of all bushing-type instrument current transformer purchases per year and is dominated by four players that hold approximately 77% of the market share. While customization is available, standardization of options and designs is the prevalent trend in this market. As a circuit breaker producer, product quality is a given, and you cannot risk your company’s reputation on anything less. Purchase price is very important, but so are the costs associated with carrying inventory. You certainly cannot afford to buy excess inventory to keep a large safety stock on-hand, and you cannot risk stopping production due to late delivery. Timely product delivery is also paramount.

In addition, you certainly don’t want to buy your CTs from one of your competitors who could put their priorities over your own.
