Application:
Electromagnetic compatibility (EMC)
The 3RT contactors fulfill the requirements for environment category A.
Note:
When the contactors are used in an environment with frequency converters, the configuration notes in the Manual "SIRIUS – SIRIUS 3RT Contactors/Contactor Assemblies" must be observed,
Short-circuit protection
For short-circuit protection of the contactors without overload relay
Refer to the manuals for details of short-circuit protection of the contactors with overload relays
Selection guides are available for the fuseless assembly of motor feeders consisting of a 3RV2 motor starter protector and a 3RT2 contactor,
For the dimensioning of load feeders,
Motor protection
3RT2 contactors
3RU2 thermal overload relays or 3RB3 electronic overload relays can be fitted to the 3RT2 contactors for protection against overload.
3RT1 contactors
3RB2 electronic overload relays can be fitted to the 3RT1 contactors for protection against overload.
Plant and application monitoring
3RR2 monitoring relays can be fitted to the 3RT2 contactors for monitoring and measuring in the application.
Ratings of three-phase motors
The quoted rating (in kW) refers to the output power on the motor shaft (according to the nameplate).
The power rating specifications of the contactors in kW (in accordance with IEC 60947-4-1, Table G) are guide values for 4-pole standard motors at 50 Hz AC and specified voltage (e.g. 400 V AC). The actual starting and rated data of the motor to be switched must be considered when selecting the units. The motor current, motor protection device and the permissible contactor current acc. to the utilization category must be aligned with each other
