FPV-63-2P 550/800V DC MCB PV Circuit Breaker
Question And Answer
Looking for specific info?
Can this be used to isolate the pv panels from the rest of the system?max volts/amps from the string is 145/30.
Yes it may be used for that and just make sure that Amps of the breaker matchs what you need for your PV panels and not to exceed that.
For the 32A breaker, would that be 16A per pole?
Each pole of the breaker is rated at 32 amps but they're not additive. Either connection through the breaker will trip with an over current exceeding 32 amps
What size wire is supported and does the wire need lugs?
Hello,please use the AWG 12-10 Wire
Can this be used for AC?
There is a difference between a rated ac breaker and a dc breaker. You can use a dc breaker in an acapplication but do not use an ac breaker in a dc application. This may cause a fire and possibly as hock hazard. Ac has a zero crossing where dc is always on.
Why does it have a neg and positive marking.. .usually you just interrupt the positive in this case with single pole?
Yes, usually you just interrupt the positive with single pole. DC is directional, so by marking positive and negative poles, and wiring according to the markings, you will clear that the DC direction is from circuit breaker bottom to top, which is easy to maintain.
