IDEC Relays RH3B-ULAC120V Relay High-Temperature Durability: The specialized ignition

High-Temperature Durability: The specialized ignition sensor rod alloy prevents warping and surface degradation in high-BTU burner assemblies

preventing ground loops and protecting sensitive controllers from noise or transients on the primary 24V line

since Nordyne manufactures Miller and Intertherm

and 243-SR models where a robust 1-piece clamp is required for the upper housing assembly

Direct Supercession: Seamlessly replaces the legacy 311100 gasket with updated material specs for improved longevity
