Three pole GFCI?

[JES2727]

I've never seen a three pole GFCI breaker, but I need three of them - ITE type BL. Does such a thing exist? If not, is there another way to protect personnel in a wet area with 3 phase circuits?

I'm curious, what's the specific application?

You could use 5 240v GFCI breakers for 10 ungrounded conductors, total.

These are pricey, thought I needed one for a pool application till I read the fpn. There are also motor control units now with overload,lost leg and gfci protections. Can you substitute devices for the breakers?

what current? do you have to use breakers or can you have downstream protection?

there is that leviton deadfront with the CT on the back, it is listed with some combinations of contactor that gives you 50 or 60a 3ph. Its only a listed component though so you would need a panel shop to put it in an enclosure with the contactor...

Theres also this http://www.bender.org/documents/LG100.pdf

I am sure there are some other options as well...

Thanks for the replies.
We're renovating a small production facility. It's a wet process. There's water and stainless steel everywhere. They'd like GFI protection on all the receptacles. We're installing wiring for a couple of 30A/208V 3 phase circulators, and a 30A/208V 3 phase mixer.
Looks like the ground fault monitors from Bender Inc might do the trick. Thanks for the lead.

ah, youre in luck if you only need 30a 3ph. Hubbell makes a 30a 3ph 120/208Y GFCI, p/n GFHW430 for manual reset, and GFHW431 for automatic reset. This is a hardwired unit, nema 4X. They also have a 30A 3ph inline model for portable use models GFP4305 and GFP4315
