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.
Higher-Current Range for Larger Motor Applications
With an 11-16A adjustment range, the 3RU2116-4AB0 extends motor protection coverage to larger loads than the smaller 3.5-5.0A variant, suiting a broader range of motor sizes within the same compact S00 platform.
Direct, Space-Saving Contactor Mounting
Electrically and mechanically optimized to match 3RT contactors, the 3RU2116-4AB0 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.
Broad Application Coverage in Industrial Motor Control
Reliably protecting loads and other switching and protective devices in the respective load feeder against overload, phase asymmetry, and phase failure, this overload relay supports dependable motor protection across a wide range of industrial automation setups.
