FAQs
For proper installation, mount the BAB2050V on a compatible panel using the bolt-on method, ensuring a two-pole arrangement that fits the panel cutout. Verify the 120/240 V supply, confirm a 50 A load, and use appropriate hardware. This approach minimizes misalignment and improves field reliability during upgrades or new builds.
The 50 A rating pairs with a 10 kAIC interrupt rating to handle high fault currents typical in motor circuits. The thermal-magnetic core provides quick protection against both overload and short-circuit, reducing wear on motors and contactors while maintaining safe startup conditions in automated lines and control panels.
No. The BAB2050V is a non-interchangeable design with specific mounting, pole count, and rating. This ensures predictable performance and avoids mismatches in interrupt ratings or voltage compatibility, but it requires selecting the exact model for panel substitutions or upgrades.
The BAB2050V is UL Listed and CSA Certified, with HACR rating noted in catalog materials. These certifications support regulatory compliance, safety verification, and compatibility with HVAC and motor load applications, streamlining approvals for industrial and commercial installations.
The device carries a 1-year warranty, reflecting Eaton’s commitment to reliability. This includes access to replacement parts and service guidance, helping you manage spare parts inventories and minimize downtime across panel refurbishments or new builds.
