Location: Wilsonville, OR, USA
Segment: Pumps and wastewater
Challenge: Needed miniature circuit breaker with ground fault quickly
Solution: CurrentWatch with ground fault
Results: Customer met critical ship date and provided ground fault protection for 50 percent less
Eaton’s Roger Stafford explains, "Mitchell Lewis & Staver, an integrator specializing in pumps and controls for wastewater treatment applications, had only been buying control power transformers from us. However, at the last minute the company discovered that it had to provide MCB with ground fault for panels that had to be shipped in two days. The company had called numerous suppliers and found that no one had the MCB with ground fault in stock, and since this is a special order component, it would take time to get it."
"When the company’s engineer called us, I explained that not only would our new CurrentWatch sensor wired to a shunt trip in the breaker meet its needs, but that we also had the product in stock. He was also pleased to learn that our product has the same ground fault sensitivity as the MCB with ground fault."
After talking with others at the company, the engineer called Stafford back and ordered it. Mitchell Lewis & Staver was impressed with how the CurrentWatch with ground fault could meet its needs, as well as the fact that it cost 50 percent less than the MCB with ground fault.
Staffords adds, "The company might have had to redesign the panel to accommodate the MCB with ground fault. However, the CurrentWatch’s compact size enabled it to fit into the existing panel."
"While not every engineer or consultant would accept the CurrentWatch as an alternative to a MCB with ground fault because of the way the specification is written, it does provide a viable, economical solution in many applications."
"As a result of Eaton’s ability to provide an economical solution to meet time-critical needs, we believe that we have earned Mitchell Lewis & Staver’s confidence, which we hope will lead to a stronger business relationship."
