The 11A rating is for steady-state resistive loads. Motors or capacitive loads (LED drivers) may have 5-10x inrush. Derate to 5-7A or use a larger contactor. f4901 11a 24v schematic install
: Use standardized symbols for the power source (24V battery/transformer), switches, and the F4901 component to ensure universal readability. Line Assignment Control Side (24V Coil) F4901 Relay Load Side
When driving a solenoid or motor, add a flyback diode (e.g., 1N5404) across the load, cathode to LOAD, anode to GND. The F4901’s internal body diode does not clamp negative inductive kick sufficiently. A1 (Coil+) COM (C) ---->
