3UA thermal overload relays protection switch
The 3UA thermal overload relay from Xinli Electric is designed for AC power systems operating at 50/60Hz with a rated voltage up to 660V. It supports current ratings from 0.1A to 630A and is specifically engineered to protect AC three-phase asynchronous motors against overload and open-phase conditions. The relay includes a temperature compensation feature, allowing reliable operation in ambient temperatures ranging from -25°C to 55°C.
This protection switch incorporates adjustable current settings with overlapping thermal element values, providing flexibility for customer selection. The design includes a test push button for breaking NC contacts, an operating indication feature, and free trip characteristics to ensure safe and predictable performance. Thermal overload relays like the 3UA are typical in industrial motor control circuits, where they serve as a critical safety component to prevent motor damage from excessive current or phase loss.
Common applications include manufacturing plants, HVAC systems, and industrial machinery where motor protection is essential. Buyers typically source these relays for integration into control panels or motor starters. The unit is compatible with standard industrial mounting configurations, and its compact design allows for easy installation in tight spaces. Importers should confirm compatibility with their existing motor systems and voltage requirements before ordering.
