FD50 Primary Resistor - EPCT Fire

The FD50, type EPCT Fire Controller is selected when it is necessary to meet limitations on inrush current. A resistor is inserted in the power supply to the motor for a smooth acceleration. The main contactor by-passes the resistor after a short acceleration time and applies full voltage to the motor terminals. Starting line current is 65% of the across-the-line starting inrush (approximately 390% of rated full load amperes)
