Description
The 2TC12 series single-phase circuit breakers provide reliable state-of-the-art circuit protection for aerospace power systems. The compact and lightweight design makes these circuit breakers well suited for aircraft avionics and electronic systems. The 2TC series ratings is coordinated so any rating will trip before another rating twice its capacity in the event of a fault. Ambient temperature compensation allows the 2TC circuit breakers to operate where temperatures exceeds the 160°F maximum of non–ambient compensated thermal circuit breakers and may also operate in temperatures as high as 150°F without derating the circuit breaker while eliminating the need for added cooling.
Includes hardware.
This 2TC12 circuit breaker (Alternate Part# 2TC12-3) is rated for 3 amps.

Frequently asked
Does the 3 Amp Circuit Breaker/Includes: Nut-washer key plate and screws for terminals. 2TC12-3 include certification paperwork?
This item is supplied as "Condition disclosed" rather than with full 8130-3 traceability — normal for some condition codes, and it does not mean the part is unusable, only that the paperwork profile differs. Check the listing for exactly what documentation is included, and request any available records before you purchase if your installation requires them.
What condition is this part?
This part is listed in condition NE — Condition disclosed. Condition codes describe how a part reached its current state (for example new, overhauled, serviceable, repaired, or as-removed) and directly affect what paperwork ships with it and how it should be installed. See the Glossary for the full definition of every condition code we use.
How fast does it ship?
This item is currently on backorder, meaning demand has temporarily outpaced our stock and a new shipment is inbound from the manufacturer or our supplier. Request a quote and we will confirm the current estimated delivery window before you commit. If your aircraft is grounded, AOG expedited handling is available on request.
Can I return it?
You may return this item within 30 days of delivery if it is unopened, uninstalled, and in its original packaging. Items that have been installed, powered on, opened hazmat, or separated from an attached 8130-3 tag are non-returnable because their airworthiness status can no longer be confirmed once removed from the part. See our Returns policy for the full process.
