IDEALLY OR AS PER STANDARD: KNOW EXACLY WHAT IS WRITTEN IN A MOTOR NAMEPLATE AS EXAMPLE ON THE FOLLOWING PARAMETERS; A. FULL LOAD CURRENT(AMPS) = SAY 50 AMPS. B. SERVICE FACTOR = USUALLY DECLARED AS = 1.15 THE NORMAL AND ACCEPTED PRACTICE IS TO MULTIPLY THE FLA = 50 AMPS BY 125% AND THE RESULT IS 62.5 AMPS. THIS IS THE MAXIMUM ALLOWABLE OVERLOAD CURRENT TO PROTECT THE MOTOR FROM INSULATION OR WINDING DAMAGE. THE 25% PERCENT ALLOWANCE = 62.5 AMPS WILL BE SET TO AN OVERLOAD RELAY TO CUT OFF WHEN REACH. IF THE SERVICE FACTOR IS AVAILABLE = 1.15 -- THIS MEANS THE MOTOR IS CAPABLE OF RUNNING UP TO 15 PERCENT HIGHER (OVERLOAD) THAN FULL LOAD CURRENT WITHOUT DAMAGE BUT REDUCING BEARING AND INSULATION END-OF-LIFE.

What is the purpose of I3 in mccb?
In a Molded Case Circuit Breaker (MCCB), I3 typically refers to the third current setting or rating, often associated with the overload protection function. It helps define the maximum current that the breaker can handle continuously without tripping. This setting is crucial for protecting the electrical circuit from overload conditions, ensuring safe operation, and preventing damage to equipment. Properly setting I3 helps balance the load and enhances the reliability of the electrical system.

don't overload it, have a look on the transformer their should be an input voltage and an output voltage if take fails just try and see if u can overload it when you do try and figure out the voltage and get a new transformer;)!!!!!
