The Littelfuse AA1-B0-24-650-5D1-C is a single-pole magnetic hydraulic delay circuit breaker rated for 50A at 277V. It features a lever actuator and is designed for panel mount installation. The magnetic hydraulic delay mechanism provides reliable overcurrent protection with a time-delay characteristic that helps avoid nuisance tripping from transient inrush currents.
This circuit breaker is suitable for a variety of electrical distribution and equipment protection applications where a 50A, 277V rating is required. The panel mount design allows for secure installation in control panels, power distribution units, and other electrical enclosures. The lever actuator provides clear visual indication of the breaker's status.
As a magnetic hydraulic delay type, this breaker offers consistent performance across a wide temperature range and is less susceptible to ambient temperature variations compared to thermal breakers. The 1-pole configuration protects a single phase or circuit path.
