3RU2136-4KD0 SIEMENS

The 3RU2136-4KD0 is a Siemens overload relay designed to provide comprehensive motor protection. This particular model offers a current range of 62 to 73 Amperes, making it suitable for motors with corresponding current requirements. It belongs to size S2, indicating its physical dimensions and compatibility with similarly sized contactors and motor starters. The relay operates under Class 10A tripping characteristics, ensuring a specific time-current response curve for effective overload detection. Mounting is simplified through direct contactor mounting, reducing installation time and complexity. The main circuit connections utilize screw terminals for secure and reliable wiring, while the auxiliary circuit employs spring-type terminals for quick and vibration-resistant connections. Users can select between manual, automatic, or remote reset options, providing flexibility in responding to overload events. This overload relay is an essential component for safeguarding motors against damage from overcurrent conditions, enhancing operational reliability and minimizing downtime. It is designed to protect motors from thermal overload, phase failure, and phase imbalance.
