The total clearing I

at power factor of 15% are given in the

electrical characteristics. For other volt-

ages, the clearing I

plying by correction factor, K , given as

a function of applied working voltage,

Arc Voltage

This curve gives the peak arc voltage,

during its operation as a function of the

power factor of 15%.

Power Losses

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

is given as a function of the RMS load
