AA1-B0-24-640-5D1-C Description

Short technical summary and product information.

The AA1-B0-24-640-5D1-C is a single-pole magnetic hydraulic delay circuit breaker from Carling Technologies/Littelfuse. It is rated for 40A continuous current at 277V AC. The hydraulic delay mechanism provides time-delayed tripping to accommodate inrush currents while protecting against sustained overloads and short circuits.

 

This circuit breaker features a panel mount design with a lever actuator. It has no illumination. The breaker is approved by CCC, CSA, and UL, indicating compliance with international safety standards. Environmental compliance includes RoHS3, REACH unaffected, and MSL 1, though these are unverified.

 

Typical applications include overcurrent protection in industrial control panels, power distribution, lighting systems, and HVAC equipment. The panel mount configuration allows for easy installation in enclosures and distribution boards.
