The AZK1M-5-2S is a single-pole automatic circuit breaker designed to protect aircraft electrical circuits from unacceptable current overloads and short-circuit currents in direct and alternating current systems.

Within electrical distribution systems, the circuit breaker performs automatic disconnection of protected circuits when current exceeds permissible magnitude or duration, ensuring protection of wiring and connected equipment.

The circuit breaker is used in aircraft electrical systems operating on DC and AC power, including circuits with increased frequency, under a wide range of environmental conditions.

The product is also known under alternative designations AZK1M-5-2S, which refer to the same product type.
