FAQs
The BAB3050HI uses bolt-on mounting, designed for straightforward integration into 240 V three-phase panels and distribution boards. Verify panel clearance, align mounting holes with the enclosure, and torque fasteners to Eaton’s specifications. Ensure the four-wire configuration is accommodated and that conductor sizing matches the 50 A rating for safe, compliant installation.
Key specs include a 50 A amperage rating, 10 kAIC interrupt rating, three-pole configuration, and 240 V operating voltage. It is HACR rated and UL Listed with CSA certification, and supports a 120–240 V shunt trip option for remote shutdown. These features collectively ensure reliable protection, safe fault clearance, and regulatory compliance in industrial panels.
Yes, the BAB3050HI is well-suited for motor protection in three-phase distribution panels and motor control centers. The 50 A rating and 10 kAIC capability handle typical motor fault scenarios, while HACR rating and UL/CSA certifications support safe operation and compliance in manufacturing environments. For high starting currents, coordinate with upstream protection to avoid nuisance trips.
The BAB3050HI is UL Listed, CSA Certified, and HACR rated. UL and CSA certifications confirm safety and performance to recognized standards, while HACR rating indicates suitability for electrical heating, air conditioning, and refrigeration equipment. Together, these certifications simplify code compliance, audits, and integration with building management and safety interlocks.
Expect reduced downtime from fewer nuisance trips due to precise thermal-magnetic protection, faster fault clearance with 10 kAIC capability, and easier maintenance thanks to bolt-on mounting for quick retrofits. The 50 A, 240 V three-phase design optimizes protection for mid-size panels, delivering reliable performance with lower installation and service costs over the equipment’s life.
