3UA5000-0J SIEMENS

The 3UA5000-0J is a thermal overload relay designed for direct mounting onto contactors or starters, providing reliable protection against motor overloads. This relay offers a setting range of 0.63 to 1A, allowing precise adjustment to match the motor's full-load current. It features both a normally open (NO) and a normally closed (NC) auxiliary contact, providing flexibility for signaling and control circuits. The thermal overload relay operates on the principle of bimetallic tripping, responding to the heat generated by the motor current. This ensures accurate and dependable overload protection, preventing motor damage due to excessive current draw. The 3UA5000-0J is a crucial component in motor control systems, safeguarding motors from overheating and extending their lifespan. Its compact design and direct mounting capability simplify installation and reduce panel space requirements. This overload relay is suitable for a wide range of motor applications, providing essential protection and enhancing system reliability. By accurately monitoring motor current and responding to overloads, the 3UA5000-0J helps to minimize downtime and prevent costly motor repairs.
