Устойчивость к токам КЗ
Устойчивость шинной системы к токам КЗ зависит от длины шинных суппортов и их сечения.
Устойчивость всей системы к токам КЗ зависит от шинных суппортов и адаптеров автоматических выключателей или разъединителей. Если одна из этих величин ниже чем ожидаемые токи КЗ в месте монтажа, токоограничивающие защитные устройства должны быть установлены выше шинной системы 8US.
Таблица ниже помогает осуществить выбор для этих целей.
