Design and Performance
Current-Dependent Protection Against Overload and Phase Failure
Designed for current-dependent protection of applications with normal start-up conditions, this relay guards against impermissibly high temperature rises resulting from overload or phase failure, triggering trip via bimetal strip deflection under sustained overcurrent.
Direct, Space-Saving Contactor Mounting
Electrically and mechanically optimized to match 3RT contactors, the 3RU2116-1FB0 can be directly mounted onto compatible contactors to save panel space, in addition to standalone individual mounting.
Clear Trip Status Indication with Flexible Reset
The “Tripping” state is signaled by a switching position indicator, with resetting available manually or automatically after a recovery time has elapsed, giving flexibility to match reset behavior to the application’s safety requirements.
Standards-Compliant Class 10 Trip Response
A Class 10 tripping characteristic conforming to IEC standards provides fast, standards-compliant response to overload conditions, helping protect connected three-phase motors from thermal damage during sustained overcurrent events.
Broad Application Coverage in Industrial Motor Control
Commonly used in MCC panels, pump applications, conveyor systems, compressors, and HVAC units, this overload relay supports dependable motor protection across a wide range of industrial automation setups.
