FAQs
The BAB2050I is a two-pole, 50 A device designed for 120/240 V distribution panels and can be wired as part of a 240 V, three-wire system. Ensure proper mounting in compatible panels, verify the 2.563 in depth, 3 in height, and 2 in width fit your enclosure, and confirm the non-automatic operation aligns with your reset practices.
The 10 kAIC interrupt rating indicates the breaker can safely interrupt fault currents up to 10,000 amperes at its rated voltage. This provides high fault tolerance in systems with significant short-circuit potential, reducing the risk of equipment damage and fire and helping maintain panel integrity during abnormal conditions.
Yes. The BAB2050I carries an HACR rating, meaning it is designed to provide motor-friendly protection and compatible performance when used with motors and mixed loads within 240 V distribution panels, helping meet standard motor control requirements while simplifying device selection.
The BAB2050I is UL Listed and CSA Certified, both indicating regulatory compliance and safety testing to recognized standards. These certifications give engineers confidence in reliability, facilitate compliance documentation, and support procurement in regulated environments where approved components are required.
With a 1-year warranty, non-interchangeable BAB type construction, and standardized dimensions, the BAB2050I simplifies stocking and replacement. Its robust interruption rating and motor-friendly HACR characteristics reduce downtime and maintenance labor, delivering predictable performance and potentially lower long-term ownership costs for panel builders and maintenance teams.
