Power and interconnect

Breakers, batteries, terminals, wire, and the sleeves that finish the run.

Aircraft electrical work is unforgiving of “close enough.” Open the leaf for the family you are on — circuit breakers, ring terminals, solder sleeves, heat-shrink, batteries — then search the PN or NSN. A listing is not a wiring-diagram approval.

Protection first

Trip curves and contact ratings are not optional color.

Thermal, magnetic, and combined breakers are not interchangeable because the panel hole looks similar. Capture manufacturer, amp rating, and lockout needs on the desk request.

Frequently asked questions

What electrical parts sit in this department?

Batteries, circuit breakers, connectors and plugs, terminals, splices, wire, heat-shrink, solder sleeves, relays, switches, static wicks, and related interconnect hardware. Open the leaf that matches the work card.

What types of circuit breakers do aircraft use?

Thermal, magnetic, and thermal-magnetic designs are common. They are not drop-in substitutes. Use the circuit-breakers leaf and the exact manufacturer part number.

Who typically manufactures aircraft circuit breakers?

Observations may show labels such as Klixon/Sensata, TE Connectivity, E-T-A, Honeywell, and Eaton when recorded. A label is not an endorsement or a form-fit-function statement.

How do I pick the correct part?

Start with the manufacturer part number from the illustrated parts catalog or maintenance manual. If an NSN is listed, search that next. Confirm finish, dash number, and engine or airframe applicability before opening an RFQ.
