The Littelfuse AA1-B0-26-625-5B1-C is a single-pole magnetic circuit breaker employing a hydraulic delay mechanism for overcurrent protection. It is rated for a continuous current of 25 Amps at a maximum voltage of 277 Volts AC or DC, making it suitable for branch circuit protection in various electrical systems.
The breaker uses a magnetic (hydraulic delay) trip characteristic, which provides time-delayed tripping for momentary inrush currents while offering fast response to sustained overloads and short circuits. The hydraulic delay element ensures the breaker is less sensitive to ambient temperature changes compared to thermal breakers.
This unit is designed for panel mounting and is operated via a manual lever actuator. It is a non-illuminated device. The compact 1-pole form factor allows for efficient use of panel space in control panels, power distribution units, and industrial equipment.
The current rating is 25A.
The voltage rating is 277V.
It is a Magnetic (Hydraulic Delay) circuit breaker.
It is a 1-pole circuit breaker.
It is a Panel Mount circuit breaker.
It uses a Lever actuator.
