8407-040 OBSOLETE
- Transformer 480/24V 50 VA
The Bard 8407-040 is an OEM control transformer used to step down 480V line power to 24V for the low-voltage control circuit in Bard wall-mounted HVAC equipment. Rated at 50 VA, it provides the steady 24VAC supply needed for reliable operation of components like contactors, relays, and control boards, helping prevent intermittent control issues caused by weak or failing transformers. Use this part when you have confirmed a 480V primary system and need the correct Bard-specified transformer to restore proper control power and dependable system response.
