The Siemens 3RH1911-1GA22 auxiliary switch block is designed to meet diverse control requirements. As part of the SIRIUS series, this component is equipped with screw-type terminals that facilitate secure connections. The switch block includes a setup of two normally open (N.O.) contacts and two normally closed (N.C.) contacts, allowing for flexible circuit designs.

With front snap-on mounting, installation is straightforward, ensuring an efficient setup process for various applications. In terms of performance, the device can handle different operating currents according to its voltage ratings:

  • At AC-12, it can manage up to 10.0 A at both 24 V and 230 V.
  • In AC-15 mode, it operates at 6.0 A for both 24 V and 230 V levels.
  • When dealing with 400 V, it supports up to 3.0 A, at 690 V, a maximum of 1.0 A is permissible.

For DC-13 applications, it efficiently manages 6.0 A at 24 V, reducing to 2.0 A at 60 V, 1.0 A at 110 V, and 0.3 A at 220 V. This broad range of operating currents indicates the switch block's versatility in handling various load demands, enhancing its applicability across different control systems.
