Product Description
The MS22073 1-2 is a 1/2-amp thermal circuit breaker meeting Military Specification MS22073 (superseded by SAE AS22073). This push-pull, trip-free breaker protects low-current aircraft electrical circuits on 28 VDC and 120 VAC 400 Hz systems. Installed directly into aircraft distribution panels, it automatically interrupts power when current exceeds its 1/2-amp rating, then resets manually after the fault clears.
Verify amperage rating, wire gauge, and reset operation per the aircraft maintenance manual before installation.
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.
