③额定电流:指断路器在额定频率下,长期通过此电流时无损伤,且各部分发热不导致过长期工作时大允许温升。④额定短路分断电流:在规定条件下,断路器能保证正常分断的大短路分断电流。⑤额定短路接通电流:在额定电压、规定使用条件和性能条件下,断路器能保证正常接通的大短路接通电流(峰值)。⑥额定短时耐受电流:在规定的使用和性能条件下,以及在确定的短时间内(例如2秒),断路器在闭合位置能承载的电流有效值。此值通常与额定短路分断电流相同。⑦额定峰值耐受电流:在规定的使用和性能条件下,断路器在闭合位置能承受额定短时耐受电流个大半波的峰值电流。⑧分断时间:从断路器接到断开指令瞬间起至燃弧时间结束时止的时间间隔。分类断路器品种繁多。
