3RT1064-6AP36 225A AC ELECTRICAL CONTACTOR 110kW MOTOR CONTACTOR 220V DC CONTACTOR
Power contactor, AC-3 225 A, 110 kW / 400 V AC (50-60 Hz) / DC operation 220-240 V UC Auxiliary contacts 2 NO + 2 NC 3-pole, Size S10 Busbar connections Drive: conventional screw terminal
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 according to the utilization category must be aligned with each other.
Operating mechanism types
3RT1 contactors
The following control and/or operating mechanism versions are available in sizes S6 to S12:
- Standard operating mechanism with economy circuit for AC and DC operation (switchover from closing coil to holding coil)
- Solid-state operating mechanism
Overvoltage damping of the operating mechanism coil is already integrated in the electronics for contactors with solid state operating mechanisms. The operating mechanisms are powered via a supply voltage with an operating range from 0.8 to 1.1 x Us, optionally also controlled depending on the chosen mode of operation. Alternatively, control is also possible via the separate 24 V DC control signal input. Various rated voltage ranges for AC/DC control are available.
The following versions are available: - With two operating modes: Direct control or via CPU input
- As above, but with additional remaining lifetime indicator (RLT)
- With fail-safe PLC input for simplification of safety applications (without mode of operation selection)
3RT1 contactors
The operating mechanisms for 3RT10..‑.A/-.N/-.P contactors are removable and can be replaced simply by unlocking and pulling them out.
NOTICE: Removal or changing of the operating mechanism is not permitted for 3RT10..‑.S contactors with fail-safe control.
Contactors in safety-related applications
Contactors are a significant part of safety-related applications. They are generally the actuators that perform the switching operation leading to the safe disconnection of the corresponding application or system.
Contactors with mirror contacts according to IEC 60947-4-1 are generally required for use in safety-related applications. Most of our contactors meet this requirement; a corresponding note can be found in the technical product data sheet.
Contactors with increased tamper protection
Increased tamper protection can be ensured either by using our contactor versions with factory-fitted, permanently mounted auxiliary switches which are protected against mechanical external operation (e.g. 3RT2...‑.....-3MA0 contactors and 3RT1...‑....-3PA0 contactors), or by using the 3RT2916-4MA10 or 3RT1926-4MA10 sealable cover as an accessory.
Connection of contactors to fail-safe control modules
While contactors with small powers can be connected directly to the outputs of a fail-safe controller, implementing safety-related applications with standard contactors with higher power is much more complicated and elaborate because of the necessary coupling links. Due to their fail-safe control input, the special versions in sizes S6 to S12 (3RT10..-.S) provide a much simpler way of doing this.
