The 7277 series low amperage 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 low amperage circuit breaker is used extensively as primary electrical circuit protection on general aviation aircraft.
The wider calibration limits of the 7277 circuit breaker also allows it to be used in applications such as:
- protection for data processing and telecommunications equipment
- flight simulators
- material handling; and
- other industrial, electronic equipment.
