About this product
The MS22073-2 is a factory-new aircraft circuit breaker supplied with traceable paperwork. A circuit breaker is an electrical protection device that detects overloads or short circuits and automatically opens (trips) to isolate a faulty circuit, protecting wiring and equipment from damage. When the fault is cleared, the breaker is reset to restore power.
