Siemens 3RK1911-1AF22 Main Breaker Panel

Product Overview

The Siemens 3RK1911-1AF22 is a hybrid fieldbus connection component from the ECOFAST product line, designed to merge bus and power supply connections in a single interface. This module transitions from IP20 to IP65 environments, enabling the connection of control and power cabling. Its robust design supports the use of copper (CU) contacts, ensuring reliable conductivity. The 2-channel configuration allows the connection of two sets of bus and power lines, making the unit suitable for linking devices such as sensors and actuators. The “infeed” designation indicates that the Siemens 3RK1911-1AF22 can serve as the main connection point for power distribution within a section of the network.
