Honeywell R4348 Flame Relay

The R4348B is a flame switch for continuous operation to indicate presence or absence of a flame and to be applied in large commercial or industrial burner installations.
The R4348B includes a 3-pole flame relay which is energized when flame is sensed and de-energized when "no-flame" is sensed as well as a 3-pole line voltage "load relay". For all type of burners with unlimited capacity.
