It seems to be a polarized breaker, will it work properly to charge and discharge the batteries through it? I.e. current reverses during the charge.

Wrong! there is a stamp in molding by poles which indicates which side is battery (batt) and Auxiliary aux. Battery side is on top in most cases.

150A or 200A manual reset circuit breaker will be ok between battery bank and 3k inverter, using 2/0 wire? Or should I fuse instead.?

Remember 2/0 Copper Wire is rated up to 170 Amps. Installing a 200A breaker risks the chance of the wire overheating and causing a fire.

Would this 40amp be suitable for connecting my new 4000w generator to the main switchboard?

No! This is a DC rated breaker if your generator makes AC power which I suspect it does you need a traditional AC breaker.

why there is more than 10% voltage drop in the Circuit Breaker ?

If you're measuring 10% voltage drop across this breaker you have something wrong going on. High resistance within the Breaker.

great product

I'm in the exterior cleaning business and this is a necessary component for hooking up electric to various equipment. Because of this the chemicals I use are highly corrosive in their pure form before blending for use. I do have to replace this once a year. With that said, if it weren't for the chems used nearby this unit, it would last 5 times longer.Great product and received very fast.
