The Littelfuse AA1-B0-34-420-911-Q is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical systems. It is rated for a continuous current of 2A at a maximum voltage of 250V, making it suitable for a range of low-power circuit protection applications.
The breaker uses a magnetic (hydraulic delay) trip mechanism, which provides predictable and repeatable overcurrent protection. The hydraulic delay element allows for controlled tripping under transient overload conditions while still providing fast response to sustained overcurrents. The lever actuator provides a clear visual indication of the breaker state and allows for manual reset and switching.
This circuit breaker is designed for panel mounting, allowing for straightforward integration into equipment enclosures and control panels. The single-pole configuration protects one conductor in a circuit. The unilluminated lever actuator keeps the design simple and reliable.
The AA1-B0-34-420-911-Q carries approvals from CCC, CSA, UL1077, and UL1500, indicating compliance with recognized safety standards for circuit protection devices.
