Product Details
Robertshaw's 41-400 series Norton hot surface ignitors deliver dependable ignition in various heating systems, including furnaces, boilers, rooftop heaters, infrared burners, unit heaters, and water heaters. Made of high-purity recrystallized silicon carbide (Cristar™), these ignitors offer a combination of physical and thermal strength along with stable electrical properties. Designed to reach ignition temperatures within 17 seconds, the ignitors come with 18-gauge nickel chrome lead wires, which are embedded and metalized for maximum holding strength and electrical conductivity. These lead wires are enclosed in high-temperature fiberglass insulation, ensuring total electrical protection. The entire 41-400 series consists of 120 VAC models, with some hot surface modules rated for 208/240 volts input, stepping the voltage down to 120 VAC for the ignitor.
