Series Overview
Series Overview
-
Connector for connecting with contactor:Achieve perfect electrical and mechanical connection with the contactor. Through these connectors, the overload relay can be directly plugged with the contactor. It is also possible to choose an independent mounting bracket for independent installation.
-
Manual/automatic reset (RESET) selector switch and reset button:Through this selector switch, you can switch between manual and automatic reset. When manual reset is selected, you can reset directly on the device by pressing the RESET button.
-
Switch status indication and action mechanism test (TEST):Indicate the action status of the thermal overload relay and perform a mechanical function test on the action mechanism.
-
Overload current setting:The overload setting current can be conveniently adjusted through the large knob.
-
STOP (stop) button:When the STOP button is pressed, the normally closed contact opens, and the connected contactor disconnects. When the STOP button is released, the normally closed contact closes again.
-
Terminal:3RU7116/3RU7126/3RU7136/3RU7146 thermal overload relays are wired with screw - type terminals.
Applications
- 3RU7116/3RU7126/3RU7136/3RU7146 thermal overload relays can be used for the protection of three - phase and single - phase AC or DC motors.
- If 3RU7116/3RU7126/3RU7136/3RU7146 thermal overload relays are used to protect single - phase AC or DC loads, three poles must be used in series.
Tripping Class
- 3RU7 thermal overload relays are used for CLASS 10 normal starting conditions.
Ambient Temperature
- 3RU7 thermal overload relays have a temperature compensation function within the temperature range of - 20 °C to + 55 °C. For the temperature range of + 55 °C to + 70 °C, the upper - limit setting value must be corrected according to the given correction coefficients.
| Cabinet Temperature (°C) | Correction Coefficient for Upper - Limit Setting Value |
|---|---|
| + 55 | 1 |
| + 60 | 0.94 |
| + 65 | 0.88 |
| + 70 | 0.82 |
