Current Capacity for Vacuum Circuit Breaker

What is incoming panel and four no. out going panels? What do you mean? How many starts per hour will you have? What type rotors have AC motors got, short-circuited rotors or phase-wound rotors? What type a torque do you have? How offen will you turn off motors in start time? How long must work your system without service?

Select circuit breaker/contactor for motor load, we must to know something:

• Votlage 220V/380V/415V.
• D.O.L starting or start-delta starting.

DOL Full load curent starting 6xf.l.c and max 5secs starting time.

Star-delta starting full load current 2xf.l.c and max 15secs starting time.

For more information you can see according to IEC 60947-4-1.
