It is the capacitance values of the capacitors that are indicated by 40+5 and 45+5. Here, the first number is for the capacitance value for the main device, and the second number indicates its capacitance value for a different device, like a fan motor. Actually, a 40 5 capacitor can be replaced with a 45 5.
Learn MoreFor a 45/5 capacitor, you can safely replace it with a 50/5 capacitor. Again, the voltage has to match so please keep an eye on that. A 370v capacitor''s replacement can''t be a 440v capacitor. Also, don''t forget that a 45/5 capacitor is the best replacement for itself. Another tip is to always keep an eye on the technician who''ll do the …
