3UA Overload RelaysDescription

3UA series are bimetal thermal relays with release class 10A.With differential phase- failure protectionWith continuous current adjusting scaleWith temperature compensationWith ON/OFF indicatorWith TEST(OFF) buttonWith Manual/Auto reset buttonWith Auxiliary contacts 1 NO +1 NC insulated each otherSIGUT - Siemens patent terminal, ensures easy and reliable connection, strong shock resistance and perfect safety protection.Mounting: plug in connection with contactor or install as a single unit.

3UA Series Overload Relays are suitable for overload and phase - failure protection of AC motors with frequency of 50/60Hz, voltage up to 690 ~1000V, current up to 0.1 ~ 400A under 8 - hours duty or uninterrupted duty. The relays are also suitable for overload protection of DC magnetand DC motors.The relays comply with IEC947-4, VDE0660 and GB14048. Several functions provided by these relays are: phase-failure protection, temperaturecompensation, ON/OFF indication and manual/automatic reset. The relays can be mounted onto contactors or installed as single units.Operating Conditions

Features

The altitude of the site of installation does not exceed 2000 meters above sea levels.The ambient air temperature: -25 ~ +55°CRelative humidity does not exceed 90% at +25°C

The current-time curves show the relationshipbetween the tripping time from cold state andmultiples of the set current E. When the relayis at operating temperature and carrying 1.0 x

E, the tripping times are reduced to approxi-mately 25%. Tripping curve 3 is applicable to3-pole loads and curve 2 to 2-pole loads. Forsingle-pole loads the tripping curves liebetween curves 2 and 3. For normaloperation, all 3 bimetallic strips of theoverload relay must be heated, The overloadrelays 3UA are suitable for protecting motorswith phase control. For protecting single-phase or DC-loads, therefore, all three mainconducting paths must be connected inseries.Tripping curve 3 is then applicable.The release current with a 3-pole symmetricalload is between 105% and 120% of the setcurrent.

2. Set the scale to the rated current of the load.3. If the reset button points to H (manual) and the relay has been tripped, pressing the button puts the relay in operation again.With the door of panel closed, manual reset can be performed by means of the cable release which can be ordered (see accessories in detail).Changing to automatic reset by pressing and turning the button anti-clock wise from H to A.4. When the test button is actuated, the NC contact opens and the NO contact closes, therefore the auxililary circuit (simulation of overloadtripping) can be tested.In the “manual” position, the relay is resetted when the blue reset button is pressed. In the “Automatic” postion, the relay is resetautomatically when the button is released.5. Mounting and operating position, the relays are shown in drawings.
