Product Description

The 7277-2-7 1/2 is a Klixon push-pull thermal circuit breaker rated 7.5 amperes for aircraft electrical systems. It provides automatic overload protection on 28 VDC or 120 VAC, 400 Hz circuits with manual reset capability and trip-free operation. This breaker mounts directly to aircraft instrument panels and control systems, interrupting current flow when thermal limits are exceeded.

Installation requires panel cutout preparation and wiring verification per the applicable aircraft maintenance manual. The 7277 series offers wider calibration tolerances than the MIL-C-5809 qualified 7274 equivalent, making it suitable for general aviation and commercial aircraft electrical protection.

Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
