Bard 8402-123BX - 3 inch insertion limit switch
Bard part 8402-123BX is an OEM 3 inch insertion limit switch rated L180-30, used as a temperature safety control on Bard HVAC equipment to help protect the unit from overheating by opening the control circuit at its setpoint and resetting after the temperature drops. This style of probe-type limit mounts into an airstream or heat section where Bard engineered it to sense temperature accurately, making correct fit and rating critical for safe operation and proper shutdown behavior. If you are replacing a failed or nuisance-tripping limit, confirm the L180-30 rating and insertion length match your original part and verify the underlying cause of overheating has been addressed before returning the unit to service.

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.
