72" x 2" for VHE Series requirements

Critical Leak Prevention: Replaces cracked or warped boxes to stop condensate from leaking onto the blower shelf or furnace floor

Industrial Voltage Range: Optimized for 277V electrical distribution common in industrial and commercial facilities

though sensing bulb placement and insulation remain critical for accurate thermal feedback

technicians can restore system reliability

Watts 0226060 Dual Switch 321042-401 72" x 2" for VHEThe Watts 0226060 (Model SAN89D) is a heavy duty Low Water Cut Off (LWCO) dual switch assembly engineered specifically for steam boiler applications requiring a secondary level of safety. Built for rigorous field demands, this unit provides critical boiler burner protection by automatically interrupting the electrical circuit if the water level drops below safe operating parameters, effectively preventing dry firing and high cost heat exchanger
