If i consider your 644kW load as a motor then,
I Assumed some parameters are:
644kW Motor, Power Factor - 0.9, Efficiency - 0.9, Load
Connected Voltage - 415V Then,
I = (644*1000) / (1.732*415*0.9*0.9) = 1106Amps
Considering 20% Margin = 1106 * 1.20 = 1327Amps
Conclusion:
So, We can choose Breaker rating is higher than that
1327Amps. Generally no one use the MCCB breaker above
800Amps. So, we can prefer the 1600Amps VCB Breaker for that
644kW Load.

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
