MCCB for Motor Control Panel

Please look at the numerous previous CR4 threads on the subject (or ask an electrician).

The following information is required:

- We need to know more about the motor(s), I.e. whether this is a soft-start, on-line start etc. motor, I.e. more information about the motor and its load assuming that it is only one motor you are going to connect

- The voltage of the motor

- The upstream configuration so that we can calculate what short-circuit currents could be necessary to switch, I.e. transformers, cables, circuit breaker configuration etc.

Thank you fro your kind attention. The motor operation --- Variable Speed Drive (Hyundai) and voltage L/L 415 V AC. Short Circuit Current 50kA.

Most of the well known switchgear manufacturers have given the details in their catalog.Please refer to them like Siemens,MG,ABB,GE

is it one phase or 3 phase??

if it is 3 phase motor,you need to use 150A 50kA MCCB.

regards

its a 3Phase motor. Thank you very much for your kind attention. Thank you to all...
