0.19 to 0.2344
0.23 to 0.3035
0.30 to 0.4228
0.42 min.115

Bleeder Resistance for MY4 AC200/220V

Float capacitance (μF)Resistance (kΩ)Wattage (W)
0.01 max.Not required.-
0.01 to 0.1288
0.12 to 0.1479

1.CVV cable: Nominal conductor cross-section: 2 mm2 (7 conductors), Float capacitance between wires: 0.15 to 0.25 (μF/km).

2.The resistance wattages are reference values. Be sure to check the values in the circuit actually used.
