FAQs
Yes. The BAB3050HS is designed for bolt-on mounting, enabling straightforward installation into standard industrial enclosures and control panels. This mounting method reduces retrofit complexity and allows for quick replacements in crowded panel spaces. When planning installations, ensure clearance for the three-pole unit and secure mounting hardware to maintain proper contact pressure and fault isolation performance.
The BAB3050HS is a three-pole breaker rated for 50 A with a 10 kAIC interrupt rating and a 240 V operating range. It supports 120 V, 208 V, and 240 V systems in shunt trip configurations and is HACR rated. This combination provides robust short-circuit protection for motors, drives, and other heavy loads while meeting common electrical standards for industrial equipment.
This unit excels in machine panels, control cabinets, and process lines where reliable three‑phase protection is needed. It is particularly suitable for feeders and branch circuits powering motors, conveyors, pumps, and automation drives. Its 50 A rating and 10 kAIC capacity align with typical medium‑to‑high fault current environments found in manufacturing and packaging lines.
The BAB3050HS carries UL Listed and CSA Certified marks, and is HACR rated. These certifications confirm compliance with safety and performance requirements for commercial and industrial electrical installations in many regions. For project approvals, reference these certifications to support safety reviews, maintenance planning, and regulatory documentation.
By delivering reliable interruption with a compact bolt-on design, the BAB3050HS reduces downtime and simplifies maintenance scheduling. Its 1-year warranty and durable construction lower replacement risk, while its standard ratings ease component standardization across panels. Over the lifecycle, this translates to lower spare part inventories, faster service turns, and more predictable capital planning for electrical protection upgrades.
