Special features
Bolt-on mounting
The 40 A amperage rating paired with a 10 kAIC interrupt rating provides selective protection for motor and control circuits, reducing thermal stress and extending component life. In three-phase 240 V systems, that strength helps prevent nuisance trips and outages, keeping production lines available. Bolt-on mounting simplifies installation in tight spaces and improves vibration resistance, enabling quick retrofits and maintenance in existing enclosures. Remote trip capability via 24/48 Vdc shunt trip enhances safety interlocks in automated lines, allowing automatic shutdown on fault signals without manual intervention. HACR rating, UL Listed and CSA Certified, ensures compliance for HVAC and motor loads while aligning with high standards for industrial and building automation projects. Quicklag technology balances rapid fault clearance with stability, lowering maintenance costs and improving uptime in demanding environments. The compact footprint—4 in long, 3.3 in high, 3.6 in wide—and 1.25 lb weight support easy enclosure fitment and serviceability.

FAQs
The BAB3040HS uses bolt-on mounting, which simplifies installation in compact control panels and machines. Its 4 in length, 3.3 in height, and 3.6 in width make it suitable for dense enclosures, while the 1.25 lb weight helps with handling during retrofits. This mounting method also provides solid mechanical stability in vibration-prone industrial environments.
Yes. The BAB3040HS is a three-pole device designed for 240 V three-phase systems. It provides a 40 A overload protection with a 10 kAIC interrupt rating, enabling reliable fault clearance in motor feeds and control circuits without excessive energy release that could damage components downstream.
The BAB3040HS supports a 24/48 Vdc shunt trip option for remote protection signaling. This feature allows an external control system or safety interlock to initiate a breaker trip, enhancing machine safeguarding and automation safety. Wiring should follow the manufacturer’s shunt-trip diagram and enclosure safety practices, ensuring proper insulation and fault current isolation.
The BAB3040HS carries UL Listed and CSA Certified marks, confirming compliance with widely adopted North American electrical safety standards. It is HACR rated for HVAC and motor loads, which helps meet code requirements in commercial and industrial environments and ensures compatibility with standard electrical panels.
Quicklag provides faster magnetic trip response while stabilizing against nuisance thermal trips, yielding reliable protection for motors and control circuits under fault conditions. In industrial applications such as conveyors, pumps, and automated tooling, this translates to improved uptime, reduced maintenance costs, and predictable protection coordination across multiple feeders in a panel.
