Eaton BAB2045 Thermal Magnetic Circuit Breaker - UL Listed

Two-pole protection at 45 A with a 10 kAIC interrupt rating minimizes fault energy and protects downstream drives and motors. The fast, predictable trip reduces downtime and equipment wear, translating to lower maintenance costs in busy manufacturing lines. This unit supports 120/240 V systems and bolt-on mounting in standard control panels. End users appreciate the consistent performance under load surges, and technicians value the straightforward wiring and labeling that speeds commissioning. Thermal magnetic operation provides coordinated overload and short-circuit protection with repeatable trip curves. The non-interchangeable trip type eliminates ambiguity between devices in the same panel, facilitating spare-part planning and field service. This combination is particularly valuable for motor starters, conveyors, and HVAC control circuits where steady performance under fluctuating loads is essential. Bolt-on mounting enables quick, secure installation and reduces field wiring complexity. The compact footprint (2.5 in depth, 3.5 in height, 2 in width) fits tight enclosures while leaving access for routine maintenance. At 0.69 lb, the unit adds minimal weight to panel assemblies and works with standard mounting hardware. Certified UL Listed and CSA Certified, with HACR rating for motor-load protection, the BAB2045 meets widely adopted safety standards and installation codes. This cross-border compliance supports regulatory approvals and reduces risk during audits. The included warranty and datasheet resources help procurement, QA, and maintenance teams plan reliability across plant locations. From a reliability and lifecycle perspective, the BAB2045 aligns with Eaton’s Quicklag family, delivering consistent performance across industrial environments. Its 120/240 V compatibility and proven protection improve uptime, while easy stocking and fast replacements lower total cost of ownership. In practice, engineers gain a ready-to-install solution that meets both performance targets and safety requirements.
