50 Amp Circuit Breaker with Manual Reset, 12V- 48V DC, Waterproof (50A)

50 Amp Circuit Breaker with Manual Reset, 12V- 48V DC, Waterproof (50A)

Q: 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.

Q: 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.

Q: 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.

Q: 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.
