gfci circuit breaker
Check whether the quoted item is a gfci circuit breaker with the stated residual current device function, or only a thermal-magnetic body that occupies the same slot.
Specification review for a gfci circuit breaker line
Circuit Breaker Sourcing uses this page to walk a quoted catalog number against the request. We are an independent sourcing partner. We do not issue UL, CSA, CE or IEC marks, and we have not verified any proposed model in this round. A family page that mentions ground-fault language is not proof that the quoted breaker is a gfci circuit breaker. Dual-function AFCI/GFCI devices are a different product again and must be named if that is what the drawing requires.
Input
Provide the requested ampere rating, pole count, voltage class, interrupting capacity in kA, panel series, mounting style and the protection type written on the schedule. If you already hold a factory or distributor offer, include the full catalog number as it will appear on the invoice, not a marketing nickname. Drawings, one-line sketches and photos of the existing load center help only when series and mounting are readable; they do not replace the written protection type. Optional budget and supplier preference can travel with the brief; they do not change which listing file must be produced.
State whether the gfci circuit breaker is for personnel protection on a wet-location branch, equipment protection or a code-driven replacement of a receptacle GFCI. Those uses still need the same product identity check: residual current function, test button behaviour as published for that model, and compatibility with the listed panel series. A 20 amp breaker or a 50 amp breaker with the same pole count is not automatically the GFCI version.
Review
Line up three published figures together: rated current in A, voltage class with AC or DC, and interrupting rating in kA at that voltage. Then line up protection type: thermal-magnetic, GFCI, AFCI or dual function, with the standard or test method the supplier cites for that function. Interrupting capacity is not residual current; mixing A and kA, or treating a trip curve as a ground-fault rating, stops the comparison. Confirm poles, bolt-on or plug-on mounting and the wire range in AWG on the terminals.
If the supplier proposes a different gfci circuit breaker model, re-check the listing file for that new number, the interrupting rating at the same voltage, physical height in the panel and whether the handle-tie or common-trip arrangement still matches the circuit. A substitution that keeps the ampere number but drops the residual current device function is a different purchase. Country of origin, condition (new or reconditioned) and packing belong on the same sheet so price is not compared across unequal goods.
Output
The working product of this page is a written specification list the factories can quote against: catalog number or an explicit “to be matched” duty, ratings, protection type, panel series, quantity, destination and the documents still missing. It is not a certificate, not an SCCR stamp and not a promise that the installation will pass inspection. Continue with the inquiry options, the procurement notes or the RFQ form when the file set is incomplete.
