The Bard 8615-045BX is an OEM 50 amp, 3 pole circuit breaker used in Bard wall mounted HVAC equipment to provide overcurrent protection for high voltage circuits. When a short or overload occurs, this breaker is designed to trip and help prevent damage to critical components and wiring inside the electrical compartment. As a genuine Bard replacement part, 8615-045BX is intended to match the original mounting and terminal configuration found in compatible units, making it a dependable choice when replacing a tripped, weak, or damaged breaker during service. Confirm amperage, pole count, and unit model compatibility before ordering.
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.
