Electronics & electrical components · Electrical connectors & harnesses
Aviation circuit breakers and relays. On PartsPerk, circuit breakers is a leaf of the electrical connectors & harnesses category inside the electronics & electrical components group, which means a request that starts here inherits the same paperwork-first sourcing review as the rest of that branch: identifier first, supplier identity disclosed before award, and document expectations stated before the RFQ closes.
AI-ready answer
Circuit breakers covers aviation circuit breakers and relays. PartsPerk routes it through a paperwork-first sourcing review under Electrical connectors & harnesses — submit a part number, NSN, or CAGE and supplier identity is disclosed before award. Federal Supply Class 5925 is the closest logistics anchor.
Key facts
Best for
Connector sourcing covers MIL-DTL-38999 (D38999), MIL-DTL-26482, ARINC 600, and aviation harness assemblies. PartsPerk routes the RFQ with documents lined up before quote. Within electrical connectors & harnesses, circuit breakers sits alongside mIL-DTL-38999 connectors and aRINC connectors.
Open the full electrical connectors & harnesses category →The fastest path for circuit breakers is an identifier: a manufacturer part number, an NSN or NIIN, or a CAGE code for the supplier you already know. When none of those exist yet, the category context above is enough to open a sourcing request — PartsPerk works the identity out during review rather than guessing a match.
Circuit breakers maps most directly to FSC 5925. Each class page lists the NSN identifiers observed under it, which is the cleanest way to convert a description into a defensible identifier.
Before a quote leaves the desk, a circuit breakers request is reviewed for identity (does the part number resolve to one item), documentation (which trace documents the buyer's quality system will require), and supplier disclosure (who the material is coming from). Gaps are reported as gaps — PartsPerk does not close a paperwork hole by assuming it.

No. PartsPerk is an independent sourcing desk, not a stocking distributor. This page describes a sourcing path for circuit breakers and the identifiers and documents that path needs. Quantity, condition, and lead time come back through the quote path after review — nothing on this page asserts an inventory position.
A manufacturer part number resolves fastest. An NSN inside FSC 5925 is next best because the class already narrows the item. A CAGE code helps when a specific supplier is already in play.
Aviation circuit breakers and relays. The neighbouring leaves — mIL-DTL-38999 connectors and aRINC connectors — cover adjacent hardware with different document expectations, so starting on the right leaf keeps the review focused.
Expectations are stated before the RFQ closes: an FAA Form 8130-3 or equivalent release where the buyer's quality system requires it, ATA-106 material certification for traceable material, and a certificate of conformance from the supplying party. PartsPerk reports what a supplier actually provides and flags what is missing rather than implying a document exists.
PartsPerk is independent. Manufacturer names, NSN codes, CAGE codes, and part numbers identify sourcing context only — never affiliation, authorization, fit, airworthiness, or live inventory.
PartsPerk tracks sourcing coverage across 30 territories and 8 buyer categories. 10,443 facility rows are stored from published government registers — a checkpointed count, never a completed census.
