Special features
Bolt-on mounting
Thermal-magnetic protection delivers selective trips for industrial loads. The BAB2050 combines a calibrated thermal element with instantaneous magnetic action, reducing nuisance trips while safeguarding conductors and motor circuits in conveyors, pumps, and process lines. Bolt-on mounting simplifies installation and retrofits in existing panels. With a two-pole design at 120/240 V, wiring remains straightforward and balanced, which reduces commissioning time and risk of wiring errors during upgrades. At 50 A and 10 kAIC interrupt rating, it protects feeders and branch circuits against severe faults, delivering predictable tripping behavior for motor starters and MCCs. UL Listed and CSA Certified, HACR rated, the BAB2050 meets critical standards for HVAC and commercial equipment, supporting regulatory compliance and QA documentation. The compact footprint (3.8 in x 4.8 in x 2.2 in) and 0.65 lb weight enable flexible panel layouts, while a 1-year warranty provides service continuity and cost planning. Compatibility with bolt-on Eaton ecosystems simplifies stock and maintenance planning across facilities.
