Product Description

The 7277-2-4 is a 4-amp thermal circuit breaker for aircraft electrical systems operating at 28 VDC or 115 VAC. This Klixon 7277 series breaker features a trip-free, push-to-reset/pull-to-trip actuator in a compact panel-mount form factor. It protects avionics bus feeders and distribution circuits from electrical overload and short-circuit conditions.

The breaker mounts directly through the panel with screw terminal connections per aircraft maintenance manual specifications. Manual reset capability allows pilots and maintenance personnel to restore power after a trip event without replacing the component.

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.
