Product Description
The MS26574-1 is a miniature single-pole circuit breaker rated 1 amp for 28 VDC and 115 VAC aircraft electrical systems. This push-pull thermal breaker features trip-free operation and panel-mount installation through a threaded bushing. Qualified to MIL-C-5809/MS26574 standards, it protects avionics feeders and equipment from overcurrent conditions.
The breaker automatically trips when current exceeds its 1-amp rating, then resets manually via push-pull action. Installation requires verification of rating compatibility and proper wiring per aircraft maintenance manuals and FAA AC 43.13-1B guidance.
