Bolt-on mounting simplifies installation and reduces field labor. The 3 in by 3 in footprint and two-pole configuration fit standard enclosures, enabling quick, secure attachment with predictable spacing. This translates into faster panel upgrades and less downtime during commissioning. With a 50 A amperage rating and a 10 kAIC interrupt rating, the BAB2050D delivers dependable short-circuit protection for demanding loads. This precise rating reduces nuisance trips for motor loads and conveyors while protecting wiring and components from catastrophic faults. In practice, it supports safer startup sequences and longer equipment life in process automation and HVAC applications. Quicklag thermal-magnetic action provides rapid protection with stable trip characteristics. The non-interchangeable design guarantees fixed trip curves, preventing mismatched replacements in legacy systems. This is especially valuable in retrofit projects and multi-vendor panels where consistency matters for safety and compliance. Certifications and HACR rating support compliance and risk management. UL Listed and CSA Certified approvals streamline procurement and audits, while HACR compatibility makes it suitable for HVAC equipment, fans, and compressors in commercial spaces. This combination reduces sourcing complexity and ensures reliable performance in regulated environments. Physical metrics and format enhance compatibility and maintenance. Weighing roughly 0.6 lb with dimensions of 3 in x 3 in x 2 in, the BAB2050D occupies minimal panel space and supports fast swaps. Its bolt-on mounting, two-pole construction, and non-interchangeable trip unit help preserve system integrity across service cycles, with warranty coverage that backs field confidence.

FAQs
It is designed for bolt-on mounting in two-pole panels. Ensure your enclosure supports bolt-on devices and provides a clear mounting area for a 3x3x2 inch unit. Align the breaker with the panel’s mounting points, then secure with appropriate hardware. This approach reduces field wiring complexity and speeds commissioning while preserving proper spacing for safety and thermal performance.
The BAB2050D provides a 50 A nominal current rating with a 10 kAIC interrupt rating and supports 120/240 V operation in a two-pole, bolt-on frame. Its trip mechanism is non-interchangeable, ensuring consistent protection. This combination minimizes fault damage, improves response in motor loads, and aligns with standard industrial distribution practices.
Yes, the BAB2050D carries HACR rating along with UL Listed and CSA Certified marks, making it suitable for HVAC equipment and general motor-control circuits. HACR rating indicates suitability for control of motors and compressors in climate systems, aiding code compliance and reducing risk in commercial and light industrial installations.
The BAB2050D is UL Listed and CSA Certified, with HACR rating noted in catalog notes. These certifications signal safety and compliance with North American standards, facilitate code approvals for panelboards, HVAC, and motor-control circuits, streamline supplier qualification, and reduce procurement risk in regulated industrial environments.
Maintenance centers on periodic inspection for secure seating and visible wear after panel work. A 1-year warranty provides initial risk coverage. The non-interchangeable trip and robust Quicklag design support predictable protection, making replacements straightforward and helping minimize unplanned downtime in machinery, HVAC, and process equipment.
