Eaton BAB2050HV Thermal Magnetic Circuit Breaker - CSA
Part Number: BAB2050HV
Quick Summary
The Eaton BAB2050HV thermal magnetic circuit breaker protects industrial distribution panels by delivering reliable overcurrent protection for 50 A circuits at 120/240 V. This device helps prevent nuisance trips in demanding equipment and provides a straightforward upgrade path when panel protection must scale with load growth. Certified HACR-rated and listed to CSA and UL standards, it supports safe, compliant installations in modern facilities. Its bolt-on mounting, 3-wire and four-wire compatibility, and interchangeability within the BAB family offer a practical, cost-conscious protection solution for dense industrial electrical rooms and motor-intensive environments. Engineers often require consistent trip curves and predictable coordination with upstream protective devices; the BAB2050HV maintains stable thermal-magnetic characteristics across temperature variations.

Thermal magnetic trip technology provides precise protection against overloads and short circuits, reducing the risk of damaging motor controllers and downstream devices. In high-load environments, accurate trip decisions translate to fewer nuisance trips and longer equipment life. This feature is especially valuable in continuous-process applications where downtime is costly. The 50 A rating paired with a 10 kAIC interrupt capability enables robust short-circuit handling without unnecessary panel oversizing, supporting compact yet safe protection for critical loads and moving equipment. The two-pole design supports both single-phase and three-phase layouts in 240 V distribution panels, accommodating 3-wire and 4-wire topologies to simplify retrofits and new installs alike. Bolt-on mounting speeds field wiring and reduces labor time during replacements, upgrades, or panel refurbishments. Interchangeability within the BAB family provides a scalable upgrade path, lowering spare inventory and simplifying future protection strategy for evolving electrical systems. The device’s HACR rating and CSA UL certifications underpin compliance, risk management, and predictable coordination with upstream protective devices. For installers, this translates to clearer documentation, easier certification, and dependable long-term operation in motor-driven processes.

FAQs
The BAB2050HV uses a bolt-on mounting method and is designed for distribution panels that support 240 V configurations. It integrates with 3-wire and four-wire layouts and aligns with the BAB family footprint, enabling straightforward retrofits and replacements without extensive rewiring. Verify panel cutout dimensions and mounting hardware compatibility before installation to ensure a hassle-free upgrade.
This breaker is ideal for protecting feeders and motors in industrial distribution panels at 120/240 V, up to 50 A. With a 10 kAIC interrupt rating, it safely handles short circuits typical in machine controls and conveyor systems. Its single- and three-phase compatibility makes it suitable for a range of motor control centers and panel layouts found in manufacturing and processing facilities.
The BAB2050HV is HACR-rated and CSA Certified with UL Listed recognition, ensuring compliance with widely adopted safety and electrical standards. These certifications support safe operation in industrial environments and facilitate regulatory acceptance during audits and commissioning of new or upgraded panels.
As a solid-state thermal-magnetic device, the BAB2050HV requires minimal ongoing maintenance beyond periodic visual checks and wiring integrity verification. With a 1-year warranty and robust 10 kAIC protection, you can expect reliable service in motor-intensive facilities. Plan for spare BAB family units to simplify future replacements and to maintain consistent protection across panels.
The BAB2050HV is interchangeable within the BAB family, offering a streamlined upgrade path when higher or lower ratings are needed. This interchangeability reduces spare inventory and simplifies lifecycle planning, especially in facilities that standardize on the BAB footprint. The bolt-on mounting and 240 V compatibility further support quick replacements during panel refurbishments or capacity expansions.
