3UA5800-2V SIEMENS

The 3UA5800-2V is a thermal overload relay designed to provide reliable protection for electric motors 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. Its primary function is to safeguard motors from damage caused by excessive current draw, which can lead to overheating and premature failure. The 3UA5800-2V features a user-adjustable current setting range of 57 to 70 Amperes, allowing for precise matching to the motor's full-load current. It incorporates a time-delay mechanism that prevents nuisance tripping caused by temporary overloads, such as those experienced during motor starting. The relay is equipped with one normally open (NO) and one normally closed (NC) auxiliary contact, providing flexibility for signaling and control circuit integration. These contacts can be used to trigger alarms, interlock circuits, or initiate other protective actions. The 3UA5800-2V offers a dependable and cost-effective solution for motor protection, ensuring operational reliability and minimizing downtime.
