Bard 8614-054BX - Mini Circuit Breaker 0.5 Amp

The Bard 8614-054BX is an OEM mini circuit breaker rated at 0.5 amp, used to help protect low-current control circuits in Bard wall-mounted HVAC equipment by opening the circuit during an overload condition. This boxed replacement is intended for restoring proper electrical protection and reducing nuisance failures caused by a weak or damaged breaker, while maintaining the original wiring layout and serviceability. Confirm the required amperage and mounting style against your unit wiring diagram or parts list before ordering to ensure correct fit and function in your specific Bard model.

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.
