FAQs
For bolt-on mounting, ensure the panel thickness supports the mounting hardware, use the correct mounting holes, and apply the recommended torque to avoid loose connections. Maintain adequate clearance for cooling and inspection, and verify alignment with bus bars. This approach minimizes vibration-induced wear and ensures consistent trip performance over the life of the device.
The BAB2045V is designed for 120/240 V systems and provides a 10 kAIC interrupt rating, enabling fast clearing of short circuits on medium-sized loads. With a 50 A rating and two-pole construction, it protects feeders and motors from overcurrent while maintaining safe coordination with upstream devices in industrial control panels.
The BAB2045V is listed as a non-interchangeable trip device within its catalog group. While it can be used alongside Eaton Quicklag products for comprehensive protection schemes, it cannot be swapped with interchangeable trip units without affecting listing, warranty, and compliance. Always verify panel compatibility and certification coverage before retrofitting.
This model is UL Listed and CSA Certified, with HACR-rated performance. These certifications confirm adherence to recognized safety and performance standards for motor and HVAC applications, helping ensure NEC/code compliance, safe operation in industrial environments, and smoother procurement across regulated facilities.
Expect improved uptime due to reliable tripping characteristics and robust interrupt capability, reducing unplanned outages. The bolt-on design speeds installation, cutting labor costs, while the non-interchangeable trip maintains design integrity, lowering mis-wiring risk. Overall, maintenance planning becomes more predictable, lowering lifecycle costs and supporting longer service intervals.
