Siemens Auxiliary Switch – 3RH2911-1XA40-0MA0

Overview

Auxiliary switch: Terminal designations and identification numbers for auxiliary contacts

Terminal designations

The terminal designations are 2-digit, e.g. 13, 14, 21, 22:

  • Tens digit: Sequence digit
    • Related terminals have the same sequence digit
  • Units digit: Function digit
    • 1-2 for normally closed contacts (NC)
    • 3-4 for normally open contacts (NO)

Identification numbers

The identification number indicates the number and type of the auxiliary contacts, e.g. 40, 31, 22, 13:

  • 1st digit: number of normally open contacts (NO)
  • 2nd digit: number of normally closed contacts (NC)

Examples:

  • 31 = 3 NO + 1 NC
  • 40 = 4 NO

Selection aid for mountable auxiliary switches for power contactors and contactor relays

The auxiliary switch of the 3RH29 series for mounting on the front and side can be used for 3RT2 power contactors as well as for 3RH2 contactor relays.

The possible combinations of basic unit and mounted auxiliary switch can be found in the tables below.

Where the columns and lines intersect (blue and green in the example) you will find the identification number for the combination of basic unit (column) and auxiliary switch (line).

Example 1

Basic unit: 3‑pole 3RT2017 motor contactor with 1 NO
Required: 1 NO + 4 NC (Ident. No. 14)
Result: 3RH2911‑.FA04 auxiliary switch

Example 2

Basic unit: 3‑pole 3RT2023 motor contactor with 1 NO + 1 NC
Required: 1 NO + 4 NC (Ident. No. 14)
Result: 3RH2911‑.HA03 auxiliary switch
