Establishing Levels of Selective Coordination for Low Voltage Circuit Breakers

155,00 €

Details

Addresses achieving selective coordination at high levels of short circuit fault current in the instantaneous region of the circuit breaker time-current curve by use of selective coordination tools. This requires taking into consideration more information than is typically found on conventional Time-Current Curves TCCs only. This includes molded case circuit breakers and insulated case circuit breakers. It specifically addresses instantaneous selective coordination as achieving selective coordination at high levels of fault current, and may require taking into consideration more information than is typically found on conventional Time-Current Curves TCCs only.
