Available. The Siemens 3UC5000-1J is a thermal overload relay designed to protect three-phase AC motors from damage due to overload conditions. This relay is suitable for direct mounting onto Siemens 3TF30 and 3TF31 contactors, ensuring seamless integration within motor starter assemblies. It offers an adjustable current range from 6.3 to 10 amperes, allowing precise matching to motor specifications for optimal protection. The relay features a manual reset mechanism, enabling operators to easily restore functionality after an overload event. Additionally, it includes one normally open (NO) and one normally closed (NC) auxiliary contact, facilitating integration into control circuits for status indication and further control logic. This overload relay is ideal for applications requiring reliable motor protection, such as conveyor systems, HVAC units, and industrial machinery, where safeguarding against thermal overloads is essential for maintaining operational efficiency and equipment longevity.
