The traditional operational curve-based method for instantaneous short circuit currents of power systems is still commonly used, which takes much labor with lower accurate results.
目前计算电力系统任意时刻短路电流一般仍沿用传统的运算曲线法，既耗费用户过多的精力，又使计算结果有较大的误差。
The A302 Manual Starter is a 3-phase manual motor starter and protector with instantaneous magnetic short circuit trip mechanism.
A302手动起动器是三相手动电动机起动器和保护装置，带有瞬间磁性短路跳闸机制。
Note:For CM1-160,225 four-poles breakers, the instantaneous release of N-pole (short-circuit protection) have no 5 In spec.
注：对CM1-160 、225四极断路器，其中性极（N ）的瞬时 脱扣器（短路保护）均无5In规格。
