The 3RA23 reversing contactor assemblies in sizes S00 to S3 can be ordered as follows:

• Fully wired and tested, with mechanical and electrical interlock
• All individual parts for customer assembly, see "Accessories and Spare Parts" в†’ "for SIRIUS 3RT2 Contactors and SIRIUS 3RH2 Contactor Relays".

The 3RA23 reversing contactor assemblies have screw or spring-type terminals (main and control circuits) and are suitable for screw and snap-on mounting onto THВ 35 standard mounting rails.

Complete 3RA23 reversing contactor assemblies

The fully wired reversing contactor assemblies are suitable for use in any climate. They are finger-safe according to IECВ 60529.

The 3RA23 reversing contactor assemblies of size S00 to S3 each consist of two contactors with the same power, with one NC contact (S00) or one NO contact and one NC contact (S0 to S3) in the basic unit. The contactors are mechanically and electrically interlocked (NC contact interlock).

For motor protection, 3RU2 or 3RB3 overload relays for contactor mounting or stand-alone installation (see "Protection Equipment"), SIMOCODE pro 3UF7 motor management and control devices (see "Monitoring and Control Devices") or 3RN thermistor motor protection evaluation units (see "Monitoring and Control Devices" в†’ "Relays") can be used.

Reversing contactor assemblies with voltage tap

The reversing contactor assemblies with voltage tap are required for mounting the function modules for connection to the controller via the IO‑Link or AS‑Interface communication systems. The 3RA27 function modules must be ordered separately, see "Accessories and Spare Parts" → "for SIRIUS 3RT2 Contactors and SIRIUS 3RH2 Contactor Relays" → "Modules for contactor control".

For more information on IO-Link or AS-Interface, see "Industrial Communication".

Sizes S00 to S3

Note:

The 3RA2934‑2B mechanical interlock for sizes S2 and S3 must be ordered separately.
