Siemens OLR1000 Solid State Relay Class 10 6.3-10A

Siemens OLR1000 is a solid-state overload relay engineered for three-phase motor protection, rated to monitor and react within a 6.3 to 10 A current window and identified by Class 10 for precise thermal protection, helping prevent motor damage, nuisance trips, and energy waste in crowded electrical cabinets. The device employs solid-state switching with screw-clamp terminals for secure, vibration-resistant wiring in compact control panels, enabling straightforward integration with Siemens control systems and protective schemes while reducing wear and heat generation associated with mechanical relays. Intended for common industrial loads—pumps, fans, conveyors, and other three-phase motors—the OLR1000 delivers fast overload response to limit heat buildup and extend motor life, supporting reliable operation in process automation, packaging lines, and water treatment facilities. With a small footprint and simple wiring, it fits standard electrical panels and provides predictable protection performance across varying loads and ambient conditions, making it a practical choice for panel builders and maintenance teams seeking consistent motor protection without complex setup.
