Product Details
Robertshaw's 41-400 series Norton hot surface ignitors provide reliable ignition for heating systems including furnaces, boilers, rooftop heaters, infrared burners, unit heaters, and water heaters. These ignitors are constructed from high-purity recrystallized silicon carbide (Crystal™), offering physical and thermal strength along with stable electrical properties. They are designed to reach ignition temperatures within 17 seconds and feature 18-gauge nickel chrome lead wires that are embedded and metalized for maximum holding strength and electrical conductivity. The lead wires are enclosed in high-temperature fiberglass insulation to ensure total electrical protection. All 41-400 series ignitors operate at 120 VAC, with some hot surface modules rated for 208/240 volts input that step the voltage down to 120 VAC for the ignitor.
