I have a question, is it possible to test a 3phase GFCI circuit breaker without installation? Or should i install it on a panel to test it out? Since I got one in hand and want to make sure it is function.
 
According to manufacturers of GFCI's they used to say the only real way to test a gfci is to push the test button. If it trips then it is good
 
I didn't know ge was making 3P gfci breakers. What ampacity is it?

THQB breakers are available in various 3-pole ampacities.

Maybe you’re thinking of Eaton? They’re the only major manufacturer I’m aware of that doesn’t offer miniature 3-pole circuit breakers in the BAB line.

GE (ABB) does NOT make a 3 pole GFCI breaker.

Is it possible that you have a 3 pole breaker with Ground Fault trips? GFCI is a specific type of GF trip system for protection of personnel, set to trip at 5mA of ground current. A 3 pole industrial breaker with "Ground Fault" trips would not be the same thing, it is only good as EQUIPMENT ground fault, or GFEP because the trips setting is 30 - 100mA, maybe even more. You cannot use that where a GFCI is required.

If you didn't need an actual GFCI and want to test that breaker, you might be able to if you have a "current injection test set", because GFEP breakers usually use a Residual Current Detection method and probably don't need for the trips to be powered up. FYI though, GFCI breakers DO need to be powered up because they have an internal circuit board that has to be powered, that's why GFCIs have that white pigtail to connect to the Neutral bar.
 
so what do i so?

I've had 480 volt three phase machines in dairy plant for decades. Need for GFCI not been an issue. Some this stuff is washed daily or even multiple times daily.

Mount an enclosed breaker of a manufacturer that makes one as a local disconnect
