Power Losses  
The total clearing I2t at rated voltage and This curve gives the peak arc voltage,  
Watts loss at rated current is given in  
the electrical characteristics. The curve  
allows the calculation of the power  
losses at load currents lower than the  
rated current. The correction factor, Kp,  
is given as a function of the RMS load  
current, Ib, in % of the rated current .  
at power factor of 15% are given in the  
electrical characteristics. For other volt-  
ages, the clearing I2t is found by multi-  
plying by correction factor, K, given as  
a function of applied working voltage,  
Eg, (RMS).
