Performance Overview
The Siemens 3RU6116-1EB0 is an industrial-tier 3-pole thermal overload relay engineered within the standardized compact Size S00 framework. Explicitly designed to provide reliable current monitoring protection for bimetallic current operations, this high-durability module handles adjustable thermal setting tracks spanning a 2.8 to 4.0 A bandwidth. It embeds a responsive phase-failure diagnostic architecture alongside Class 10 trip timing parameters to intercept severe current unbalances or continuous stall friction before destructive heat reaches primary motor coils. Complete with an integrated 1NO + 1NC auxiliary signaling path and standard manual/auto-reset gating toggles, it integrates cleanly into primary contactor lines to secure continuous system protection.
📋 Critical Application Check
-
Industry: Continuous-Duty Pump Starters, Industrial Ventilation Fan Shields, Mechanical Conveyor Line Feeders, Small Processing Automation Cabinets.
-
Direct Integration Efficiency: Plug-and-play architectural pinning links this relay directly beneath standard 3RT60 contactors, saving panel space and removing wiring links.
-
Fault Visibility Signaling: The integrated 1NO + 1NC isolated contacts provide seamless physical links for remote system alarm flags or safe PLC control power drops under fault conditions.
