"L class" vs "C class" for CT
"L class" vs "C class" for CT
(OP)
Hi,
I try to understand what's the difference between a C800 and a 10L800 CT.
From what i understand, it's pretty much the same thing, considering 10% error on the C class.
I think the L class is from an old standard, ASA (american standard association), and the C class from a new standard IEEE.
So, is it normal to buy a new breaker in 2013 and to have L class CT in the bushing?
Thanks

RE: "L class" vs "C class" for CT
For the "L" class in CSA, there also exists a 2.5L, which works the same way, just with an accuracy limit of 2.5% at 20 times Inom @ rated burden.

I found the CSA standard that talk about that.
