I need four units of "High Power BC1 Variable Resistor Disc Sliding Rheostat Adjustable Resistor" with a power rating of 2000 W, for a total power of 8 kW (the four rheostats will be connected in parallel). If available, please provide the maximum current supported at a voltage of 230 V, the unit price including tax (for one 2 kW rheostat), the total price including tax for all four units (8 kW), and a detailed quotation including all costs: product total with tax + shipping to Morocco + customs fees. I would like to place the order as soon as possible.
