The Littelfuse AS1-B0-44-618-131-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for reliable overcurrent protection in a variety of applications. It is rated for a continuous current of 18A at a voltage of 277V, making it suitable for use in AC circuits within this range.
The breaker uses a magnetic (hydraulic delay) trip mechanism, which provides precise and repeatable overcurrent protection. The hydraulic delay feature allows for momentary inrush currents without nuisance tripping, while still providing fast response to sustained overloads and short circuits.
This circuit breaker is designed for panel mounting and features a lever actuator for manual on/off control. The lever actuator provides a clear visual indication of the breaker state and allows for easy reset after a trip event. The unit is not illuminated.
The AS1-B0-44-618-131-C is approved by UL, CSA, and CCC, indicating compliance with major North American and Chinese safety standards. This makes it suitable for use in equipment intended for these markets.
