FAQs
The BAB3040HT uses bolt-on mounting with three-pole configuration and accepts ring or spade lug terminals. Plan for 240 V three‑phase supply, 40 A continuous rating, and appropriate enclosure space to accommodate its 3.25 in depth, 3.5 in height, and 3 in width. Ensure proper clearances and verify terminal torque requirements during wiring to maintain safety and performance.
Key specs include a 40 A current rating and a 10 kAIC interrupt capacity, rated for 240 V across three poles. The device is a non-interchangeable trip type, designed for bolt-on mounting and has HACR rating for HVAC and motor control applications. These specs translate to reliable protection for 3‑phase loads with predictable tripping behavior.
Yes. The BAB3040HT is HACR rated and optimized for motor and HVAC-related control panels, delivering protection aligned with HVAC equipment and motor control circuits. Its 10 kAIC interrupt capacity helps manage fault energy in motor and drive paths, while the 240 V three‑pole design covers standard industrial HVAC and motor applications.
The BAB3040HT is UL Listed and CSA Certified, with HACR rating noted for compatible HVAC and motor control environments. These certifications ensure compliance with safety and performance standards, simplify qualification for regulated installations, and support reliable operation in industrial facilities and automation panels.
With a 1-year warranty and robust thermal‑magnetic protection, the BAB3040HT reduces nuisance trips and downtime in high-use panels. Its solid installation features (bolt-on mounting and versatile terminals) minimize field service time during upgrades, while its non-interchangeable trip type helps maintain system integrity, contributing to predictable maintenance planning and lower total cost of ownership.
