3UA5800-2F SIEMENS

The 3UA5800-2F is a thermal overload relay designed to provide reliable protection for motors and electrical equipment against overload conditions. This relay is specifically designed for direct mounting onto contactors or motor starters, simplifying installation and saving space within the electrical panel. It features a wide current setting range of 32 to 50A, allowing for flexible application across various motor sizes and load requirements. The relay operates on a thermal-delayed principle, accurately mimicking the heating characteristics of the protected motor to prevent nuisance tripping. Equipped with one normally open (NO) and one normally closed (NC) auxiliary contact, the 3UA5800-2F provides versatile signaling options for control and monitoring circuits. These auxiliary contacts can be used to trigger alarms, interlocks, or other control functions in response to an overload event. The robust design ensures reliable performance in demanding industrial environments. By accurately detecting and responding to overload conditions, the 3UA5800-2F helps to extend the lifespan of motors and minimize downtime. This overload relay is an essential component for comprehensive motor protection strategies.
