Special features
Bolt-on mounting
The BAB3040E delivers a precise 40 A amperage rating, enabling reliable overload protection without triggering unnecessary trips in commonly sized industrial motors. This thermal-magnetic protection reduces wear on contacts and extends equipment life while simplifying protection coordination in panel boards. Ideal for three-pole, 240/415 V power circuits in manufacturing lines and HVAC machinery.With a 3 kAIC interrupt rating, the BAB3040E provides strong short-circuit clearance for demanding loads, improving equipment safety and uptime. The sturdy trip mechanism supports consistent protection across temperature variations and electrical noise typical in factory floors. Relevant for motor starters and conveyor systems in heavy industrial settings.Bolt-on mounting streamlines installation and service, reducing panel build time and field labor costs. The secure mounting also minimizes vibration-related looseness in harsh environments. Used in compact control panels where space is at a premium.Three-pole design ensures balanced protection for three-phase systems, aligning with industrial standards for motor control and power distribution. The 240/415 V voltage rating covers common European and North American panel configurations, increasing global compatibility. Particularly useful for OEMs integrating into mixed-voltage lines.Certifications (CSA Certified, UL Listed) and HACR rating simplify compliance testing and maintenance planning. The Non-Interchangeable trip type prevents mismatched replacement devices, reducing spare-part inventories and support calls. Overall, this device improves reliability, lowers total cost of ownership, and supports scalable automation projects.

FAQs
The BAB3040E uses a bolt-on mounting method designed for secure, vibration-resistant installation in standard industrial panels. Ensure the mounting holes align with your panel cutouts, tighten to manufacturer torque specs, and connect the three-pole terminals for balanced three-phase protection. Seal and inspect after commissioning to prevent dust ingress and maintain HACR-rated performance in HVAC and motor circuits.
Key ratings include 40 A continuous amperage, 3 kAIC interrupt rating, and a 240/415 V operating range. These specifications ensure reliable protection for moderately sized motors and three-phase loads, with significant short-circuit clearance margin. The 40 A setting minimizes nuisance trips, while 3 kAIC provides a robust defense against high-energy faults common in industrial environments.
Yes. The HACR rating confirms suitability for HVAC and motor-driven applications, while the UL Listed and CSA Certified marks verify compliance with essential safety standards. Its three-pole design supports balanced protection in three-phase systems, and the bolt-on mounting facilitates stable installation in enclosure spaces typical of HVAC control panels and industrial machines.
The BAB3040E carries CSA Certified and UL Listed certifications, plus an HACR rating. These signals ensure the device meets rigorous electrical safety, performance, and reliability standards. For regulated facilities and OEMs, these certifications streamline approval processes, warranty validity, and maintenance planning across global installations.
The non-interchangeable trip type reduces the risk of mismatched replacements, simplifying spare-part inventories. Its robust 3 kAIC interrupt capability improves uptime by delivering reliable fault clearance, while bolt-on mounting speeds installation and service. Together, these factors lower maintenance labor Costs and support scalable automation projects in demanding plants.
