Motor Fuse Size Calculator
A common rule of thumb is to select a fuse with a rating 150% to 175% of the motor's FLA to allow for inrush current. How do you size a fuse for a 3-phase motor? For a 3-phase motor, calculate the FLA using the formula: FLA = (kW * 1000) / (1.732 * Voltage). Then select a fuse with a rating greater than the calculated FLA.
