3UA5000-1B SIEMENS

The 3UA5000-1B 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 in electrical panels. It features a wide current setting range of 1.25 to 2A, allowing for precise adjustment to match the motor's full-load current. The 3UA5000-1B incorporates a thermally delayed tripping mechanism, which accurately mimics the heating characteristics of the motor, preventing nuisance tripping due to temporary overloads. Equipped with one normally open (NO) and one normally closed (NC) auxiliary contact, the relay provides versatile signaling options for control circuits and alarm systems. These auxiliary contacts can be used to indicate overload conditions, initiate shutdown procedures, or trigger other protective measures. The robust construction and reliable performance of the 3UA5000-1B ensure long-lasting protection for valuable motor assets. It is an essential component for any motor control system, safeguarding against costly downtime and equipment damage. This overload relay is a dependable solution for maintaining the efficiency and longevity of electric motors in various industrial applications.
