| i2t A2t | is a measure of current (I) and time (t), that would be the thermal energy let through during short circuit interruption, as the integral of the square of the current over a given time expressed in ampere square seconds. Data may refer to pre-arcing or melting i2t for high currents which is practically a constant value, or refer to an operational i2t which varies with circuit conditions |
