About this product
The Klein Tools CL390 is an auto-ranging digital clamp meter that clamps both AC and DC current up to 400A — the one to reach for where an AC-only clamp stops short. For the full function list and ratings, see the manufacturer's spec sheet. Stocked in Canada by Maple Electric — CAD pricing, ships Canada-wide, will-call pickup in Vaughan.
Common questions
What's the difference between the CL390 and the CL220?
The CL390 clamps both AC and DC current up to 400A; the CL220 clamps AC current only. Both are auto-ranging Klein clamp meters.
What is the CAT safety rating?
The listing doesn't state it — check the Klein spec sheet before panel work, and confirm the category your task requires with a licensed electrician.
Does it measure voltage too?
This listing covers the 400A AC/DC clamp function. For the full function list and measurement ranges, confirm against Klein's spec sheet for the CL390.
