This AA1-B0-32-650-5D2-C circuit breaker from Littelfuse Inc. is a single-pole magnetic (hydraulic delay) type rated for 50A continuous current at 277V. The hydraulic delay mechanism provides inverse time-current characteristics, offering precise overcurrent protection for a wide range of applications. It features a lever actuator for manual on/off control and is designed for panel mount installation.
The breaker carries approval from CCC, CSA, and UL, ensuring compliance with international safety standards. As a magnetic-type breaker, it is less sensitive to ambient temperature variations than thermal breakers, making it suitable for environments with fluctuating temperatures. The hydraulic delay provides time-delayed tripping for temporary inrush currents while still clearing sustained overloads.
Typical applications include industrial control panels, power distribution units, HVAC equipment, and other commercial electrical systems requiring reliable branch circuit protection. The compact single-pole design saves panel space while delivering robust performance.
