Reliance Electric 600686-2BR Suppressor

Reliance Electric 600686-2BR Suppressor is an RC network suppressor from the Reliance 600686 family, intended to snub switching transients in coil-driven control circuits found in legacy Reliance Electric/Baldor equipment. Marketplace listings identify the part as 600686-2BR and note it as New Old Stock (NOS), reflecting its status as a vintage but unused replacement part. In the same family, variants such as 600686-33A are referenced in manuals as RC suppressors installed across coil contacts in main-contactor applications, illustrating the intended role of these modules in protecting relays and drive electronics. The 600686-2BR is commonly sought for replacement in older Reliance/Baldor systems where coil suppression and transient protection are required.
