Rheem-Ruud SP10869NL Resistor Element Disconnect the power and performThe Rheem Ruud SP10869NL is a high performance resistor element designed for field service in heavy duty electric water heaters. Featuring a 5000W 240V rating and a stainless steel (Incoloy 800) outer sheath, this low watt density (LWD) heating component is engineered to withstand scale buildup and reduce the risk of dry firing failures. The integrated resistor is a critical feature for contractors, as it helps regulate the sacrificial anode rod
