Standards

IEC/EN 60947‑1,
IEC/EN 60947‑4‑1,
IEC/EN 60947‑5‑1 (auxiliary switches)

The contactors are suitable for use in any climate. They are finger-safe according to IECВ 60529.

3RT contactors: 4 contactors are used for switching resistive loads (AC-1) or as contactors, for example for variable-speed operating mechanisms that normally only have to carry the current.

The accessories and spare parts for the 3RT contactors can also be used here; see "Accessories and spare parts" в†’ "for SIRIUS 3RT2 Contactors and SIRIUS 3RH2 Auxiliary Switches".

For a general description of sizes S3 to S12 of 3RT contactors, see "Power contactors for switching motors" в†’ "SIRIUS 3RT contactors, 3-pole up to 250В kW".

Connection method

Main circuit

  • Size S3: screw terminals with box terminal; direct connection to the connecting bar possible with cable lugs when the box terminal is removed.
  • Sizes S6 to S12: screw terminals with connecting bars that the cables can be connected to using either cable lugs or flexible or rigid busbars. Alternatively, box terminals are available as accessories.

Auxiliary/control circuit

Sizes S3 to S12: Screw terminals

Operating mechanism types

3RT2 contactors

3RT2 contactors are available as versions with conventional AC operating mechanisms or as versions with a wide-range solid-state operating mechanism and a universal actuating voltage (AC or DC operation possible).

With an operating range between 0.8 to 1.1В xВ Us, control takes place via the control supply voltage connection A1 - A2 as is typically the case.

3RT1 contactors

The following control and/or actuator versions are available in sizes S6 to S12:

  • Conventional operating mechanisms
  • 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 0.8В toВ 1.1В xВ Us, optionally also controlled depending on the chosen mode of operation. Alternatively, control is also possible via the separate 24В VВ 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 additionally with remaining lifetime indication (RLT)
    • With fail-safe PLC input for simplification of safety applications (without mode of operation selection)
Solenoid coils/drive units

3RT2 contactors

Coil replacement is possible for sizes S0 to S3.

3RT1 contactors

The operating mechanisms for 3RT14..-.A/-.N/-.P contactors are removable and can be replaced simply by unlocking and pulling them out.

IMPORTANT:
Removal or changing of the operating mechanism is not permitted for 3RT14..‑ .S contactors with fail-safe control.

Safety 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.

In addition to the provision of safety-related device data in the technical specifications and the Safety Evaluation Tool for the easy evaluation of the overall system, as well as accessories for simple and space-saving design, 3RT1 contactors that can be controlled directly by fail-safe controllers via fail-safe modules are also available in the high current range from 275 A (AC‑1) upwards.
