Special features
Bolt-on mounting
The BAB3090HS uses a three-pole design with bolt-on mounting to deliver dependable three‑phase protection for large motors, pumps, and control panels. This configuration reduces mis-coordination across three-phase circuits and accelerates panel assembly, supporting faster commissioning and easier future upgrades in motor control centers and machine panels. The thermal-magnetic trip combines overload protection with rapid magnetic response for short-circuit events, which minimizes damage, reduces downtime, and improves safety during high-inrush starting or fault conditions. With a 10 kAIC interrupt rating at 240 V, the breaker withstands high fault currents, enabling compliant upstream protection and safer, more reliable power distribution for industrial equipment. Optional shunt-trip capability enables remote tripping for enhanced safety during maintenance or emergency shutdowns, while UL Listed and CSA Certified status helps satisfy regulatory requirements. The unit’s HACR rating confirms suitability for HVAC-related equipment, and its compact bolt-on design simplifies retrofits and new installations in confined spaces. Finally, a 1-year warranty and lightweight profile reduce lifecycle costs and simplify inventory management for maintenance teams.

FAQs
For new panel installations, mount the BAB3090HS using the bolt-on method specified by Eaton. The three-pole design aligns with standard 3-phase bus bars, allowing straightforward wiring of L1-L2-L3 and neutral where applicable. The unit’s compact footprint (4.1 in depth, 3.2 in height, 3.7 in width) minimizes panel intrusion, while labeling aids rapid field verification during commissioning. Ensure adequate clearance per electrical codes and torque fittings to maintain reliable contacts and trip performance.
Key ratings include a 90 A amperage rating, 240 V voltage rating, and a 10 kAIC interrupt capacity. These figures define what the breaker can safely interrupt and withstand in fault conditions. Use the 90 A setting for motor loads within nameplate limits, ensure upstream devices and conductors are sized accordingly, and verify coordination with upstream protection devices to prevent nuisance tripping while preserving safety margins.
Yes. The BAB3090HS carries HACR rating, signaling suitability for HVAC equipment alongside general industrial protection. UL Listed and CSA Certified status further support compliance with electrical codes applicable to HVAC racks and machine panels. Its three-pole design and bolt-on mounting provide robust protection for equipment such as air handlers, compressors, motors, and conveyors in demanding environments.
The BAB3090HS is UL Listed and CSA Certified, with HACR rating for HVAC applications. These certifications indicate adherence to recognized safety and performance standards, simplifying regulatory approvals, customer audits, and procurement processes. For engineers and procurement teams, such certifications reduce the need for additional verification tests and help ensure consistent performance across sites and service providers.
Routine maintenance should focus on visual inspection of connections, verification of mounting integrity, and periodic trip testing per site policy. The device’s 1-year warranty provides initial protection against manufacturing defects, while its durable thermal-magnetic mechanism supports long service life in typical industrial environments. Keep spare units on hand for quick swaps to minimize downtime during planned maintenance or fault events.
