With a 125 A rating, it suits mid-range protection on feeders and branch circuits, while the 2-pole design ensures both conductors trip together for enhanced safety. Its bolt-on design is ideal for field replacements, end-of-life panels, or stock management where precise BOM alignment matters.

Practical use cases:

• Replacing a failed breaker in service panelboards and load centers that reference the B2125 part number.
• Maintaining ready-to-ship spares for service vehicles to minimize downtime during electrical maintenance calls.
• Ensuring BOM accuracy in projects that require exact original-design components for compliance and documentation.
