Bard 8615-040BX - 50A 2-Pole Circuit Breaker

The Bard 8615-040BX is an OEM 50 amp, 2 pole circuit breaker used in Bard HVAC equipment to provide overcurrent protection for the unit power circuit. When a breaker is weak, nuisance tripping or failure to reset can interrupt operation and point to a needed replacement during service. Installing the correct Bard breaker helps maintain proper electrical protection to Bard specifications and supports safe, reliable system operation. Before ordering, confirm the amperage and pole configuration match your unit and verify the part number against the model and wiring diagram to ensure proper fit.

What does the "BX" suffix mean?

Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.

A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.

Example: 8406-142BX is physically identical to 8406-142.
