The 7277 series circuit breaker is physically and electrically identical to the 7274-2 style circuit breaker, with the exception that the 7277 series has wider calibration limits.
Originally developed as an alternative to slow blow fuses, the trip free 7277 is used extensively as primary electrical circuit protection on general aviation aircraft. The wider calibration limits of the 7277 has also resulted in applications including protection for data processing and telecommunications equipment, computers, flight simulators, construction, material handling and other industrial,electronic equipment.
For use on trainer / simulator applications where all breakers are operated on low ampere control current, different ampere rating inserts (amp ratings on top of push button) can be ordered.
• Light weight
• Auxiliary switch
• Longer push buttons

Exactly what I wanted. Same as the OEM breakers in my Beech.
Worked fine. BTW-I lost the nut. Aircraft Spruce is working with me to get replacement hardware. Other vendors sell KLIXON hardware kits but only ship via UPS. Might as well just by another CB from aircraft spruce
This one is not installed yet but an identical part ordered previously is installed an appears to be functioning perfectly. AC Sprucesâ€™s ordering process is so easy I tend to place orders almost impulsively as items are needed rather than waiting to place a combination order containing several things.
Great product worked for my installation. Circuit breakers are small and compact.
Great compact breakers.
As advertised, quick delivery
I have used dozens and never a problem
No, they are not FAA PMA'd or TSO'd.
The first number following 7277 is a type designator. -1 indicates auxilary (not for primary use) and the -5 has a longer push button than the standard -2.
Per the manufacturer the mounting hole should be 0.445 in diameter and the smaller hole should be 0.125
The 7277-1 has an Aux. circuit option and the 7277-2 does not.
Yes, Klixon offers a 1/2 amp breaker which would be a special order, please contact our avionics department to place the order.
These are screw type terminals.
The terminals have 6-32 X 3/16" long screws.
We have added the drawing to the Dimensions tab of the web page for review.
These circuit breakers do not have FAA Approval on their own. They were commonly installed as OEM breakers on many production aircraft, and thus might be approved under the airframe approval as replacement parts. Please confirm in your aircraft parts manual and with your A&P to ensure these can be legally installed in your aircraft.
