This whitepaper entitled, “Low Voltage Circuit Breaker Guidelines for Data Centers” from Schneider Electric’s Square D Power Systems Engineering group surmises that "circuit breaker reliability is the key to data center reliability." The paper emphasizes that consulting engineers and end users need to grasp design maintenance basics and that this baseline knowledge will ensure max reliability for a data center's UPS.
The author contends that circuit breakers have three distinct impacts on data center reliability; service continuity, minimizing human error, and optimizing maintenance. He also explains the three factors of circuit breaker design as well. This is followed by an explanation of UL 489 vs. ANSI C37 and how smart switchgear is having an impact on today’s data center.
Of course everything is about dependability. The cost associated with proper electrical maintenance is far less than that of lost production and downtime. This whitepaper in a very structured and logical way emphasizes this key point.
