Description

Siemens Auxiliary contacts are the perfect added component solutions to the main contacts. A key function of the Auxiliary contacts is they transfer data from the circuit to a logic controller, which consecutively gives instructions to the linked devices about whether to turn on or off. This instruction can also be executed remotely.

The SIRIUS auxiliary contact block 3RH2911-1HA13 has one NO and three NC contacts. This makes the auxiliary contact block an ideal complement to contactor relays and power contactors. The screw-type connection ensures easy installation. The auxiliary switches mounted at the front can be disassembled with the help of a centrally arranged release lever. Typical fields of application include motor and plant control, switching of light controls and multiplication of signals.
