Siemens OLR1250 Overload Relay is a motor-protection device rated for 8.0 to 12.5 A, designed to trip the control circuit when motor current exceeds the set range, helping prevent motor damage in start–stop duty when used with compatible Siemens contactors. The model name signals its 8.0–12.5 A protection window, making it suitable for smaller to mid‑size motors in Siemens starter assemblies. This overload relay is paired with the protective circuitry of a Siemens motor control system to provide reliable protection against overload conditions.
