Thermal-magnetic trip technology combines fast magnetic action for short circuits with a thermal curve for overloads, reducing nuisance trips and protecting equipment from damaging faults. This translates to fewer unplanned outages and longer motor life, especially in high-inertia loads common in manufacturing lines. 40 A amperage rating paired with a 10 kAIC interrupt capacity provides reliable protection for feeders and motor circuits in mid-size panels. In practice this means you can safely interrupt faults close to the source without damaging downstream devices, improving uptime and reducing replacement costs. Two-pole, four-wire configuration aligns with most 240 V three-phase four-wire systems, simplifying wiring and improving protection coordination. Quicklag and bolt-on mounting save time during installation and enable straightforward retrofits in existing distribution panels. UL Listed and CSA Certified with HACR rating support regulatory compliance and safe operation in commercial and industrial spaces. The BAB2040H is designed for distribution panels 240 V (three-phase, four-wire maximum), enabling quick compatibility with existing systems.

FAQs
To install the BAB2040H, verify the panel is 240 V and supports three-phase, four-wire configurations. Mount the unit using bolt-on hardware, connect four wires per the panel wiring diagram, and ensure the breaker is seated firmly in its slot. The device’s two-pole design and Quicklag mechanism simplify alignment and engagement, reducing commissioning time.
Key specs include a 40 A amperage rating, 10 kAIC interrupt rating, 240 V voltage rating, two-pole configuration, and four-wire compatibility. It is a non-interchangeable trip type with Quicklag technology, UL Listed and CSA Certified, and HACR rated, making it suitable for standard industrial feeder circuits and motor-related applications.
Yes. The thermal-magnetic trip profile provides reliable motor protection against overloads and short circuits. With a 40 A rating and 10 kAIC interrupt capacity, it handles typical industrial fault currents while safeguarding motors and feeders. HACR rating adds regulatory alignment for motor control centers and panelboards in manufacturing environments.
The BAB2040H is UL Listed and CSA Certified with HACR rating. These certifications indicate conformity to critical safety and performance standards, supporting compliance with national and local electrical codes. For panel builders and integrators, this reduces qualification risk and simplifies customer audits in regulated industries.
Expect improved system uptime due to reliable overload protection and reduced nuisance trips. The 1-year warranty offers initial support, while bolt-on mounting and interchangeability within the BAB family streamline replacements and retrofits. Overall, the unit lowers maintenance labor costs and minimizes downtime in 240 V distribution panels.
