Siemens OLR0560U Overload Relay

The Siemens OLR0560U Overload Relay is a thermal overload protection device designed to sit in motor starter circuits beside a contactor, providing automatic disconnect protection for AC motors when currents exceed preset limits and temperatures rise. The model's current-setting range is specified as 3.5 A to 5.6 A, enabling protection tuned to a motor’s running current and preventing damage from sustained overload conditions. As part of Siemens' overload-relay family, the OLR0560U is designed for use in electrical control panels and motor control circuits where compact protection is required. When integrated with compatible Siemens control components, it provides a practical option for adding thermal protection to small and medium-sized motors in industrial automation environments. The OLR0560U is part of Siemens' overload-relay family, representing the company's approach to motor protection in industrial control environments. The 3.5 A to 5.6 A rating indicates the protective window relative to motor current, meaning the relay is intended for motors whose running current falls within that range.
