The thermal bimetallic release protects motors against overload and phase failure; the integrated auxiliary switch provides a normally-open signal contact that changes state on trip. ## Mounting and motor ratings This relay mounts directly onto a contactor — no DIN rail needed — and can be installed in any orientation. At 480 V and 600 V the maximum rated current is 16 A. Per-pole power dissipation is 2.7 W. Temperature compensation is active from -40 to +60 °C, keeping the trip curve stable across the working range.","metaTitle":"Siemens 3RU2116-4AJ0 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2116-4AJ0 SIRIUS thermal overload relay, Class 10 trip, size S00, 690 V rated, 50/60 Hz.
