Special features
Bolt-on mounting
90 A amperage rating provides precise current limiting for branch circuits in mid-range motor drives and control panels. This ensures overload protection aligns with system design, reducing nuisance trips and extending contactor life. In practice, it supports reliable protection for 240V circuits feeding pumps, conveyors, and automation modules. The thermal-magnetic trip mechanism combines thermal overload protection with instantaneous magnetic trip for short circuits. This yields faster shutdown of fault conditions, minimizing equipment damage and arc flash potential, while maintaining selectivity in multibreakers. With a 10 kAIC interrupt rating, the BAB2090H can safely interrupt high fault currents typical of industrial power distribution, reducing the risk of damage to feeders and downstream equipment in MCCs and control panels. Bolt-on mounting and two-pole construction provide secure installation and straightforward field retrofits, simplifying panel updates and reducing installation time in dense electrical rooms. The device is UL Listed and CSA Certified with HACR rating, ensuring compliance for HVAC and general industrial applications while delivering predictable performance. Its compact form factor and robust enclosure support reliable operation in harsh factory environments, contributing to lower lifecycle costs and improved uptime across automation assets.

FAQs
The BAB2090H uses bolt-on mounting and is a two-pole device suited for 240V circuits. Its compact 3.9 in L, 4.9 in H, and 2.2 in W footprint fits standard protection panels and control enclosures. Verify panel cavity clearance and torque requirements, then secure with the appropriate hardware to ensure a reliable, vibration-resistant connection.
The 10 kAIC interrupt rating indicates the maximum fault current the device can safely interrupt at or below its rated voltage. In practical terms, this protects feeders and downstream equipment from high-energy faults common in industrial environments, reducing the risk of arc flash, damage, and cascading trips in motor control centers and power distribution panels.
Yes. The BAB2090H is HACR rated, which means it is suitable for HVAC control circuits in addition to general industrial protection. UL Listed and CSA Certified, it meets the safety and performance standards required for HVAC systems, process lines, and other critical loads within manufacturing and facility infrastructure.
The BAB2090H is UL Listed and CSA Certified, with HACR rating noted for compatibility with HVAC equipment. These certifications demonstrate conformity to recognized safety and performance standards, supporting successful inspections, panel approvals, and regulatory compliance across industrial and commercial facilities.
With a 90 A rating, fast thermal-magnetic trip response, and a robust bolt-on two-pole design, the BAB2090H simplifies installation and service.
