The WAGO 890-123 is a 3-pole socket with integrated strain relief housing, specifically developed for use in installation systems in the field of home automation and TEBIS TS. The product is finished in white and enables a secure and durable connection of electrical conductors with a diameter of 4.5 to 10 mm. The socket is designed for cross-sections of 0.25 to 1.5 mm², thus offering broad application versatility in electrical installation, particularly for wiring plug connectors in enclosures, distribution boxes, or on indoor devices.

Applications
The socket 890-123 is suitable for use in industrial and commercial electrical installations where a mechanically stable and pull-resistant connection is required. The integrated strain relief housing prevents the conductor from being pulled out of the connection, which is particularly important under frequent movement or mechanical stress. It is commonly used in conjunction with plug connectors in the TEBIS TS system, where a secure and reliable connection between devices and controls is necessary.

Functions and Equipment in Detail
The socket features a strain relief housing that mechanically secures the conductor and protects it from mechanical stress. The connection cross-sections of 0.25 to 1.5 mm² allow compatibility with a wide range of cable types commonly used in electrical installation. The 3-pole configuration makes it suitable for connecting live conductors, neutral conductors, and protective earth conductors in a single unit. The white coloration supports visual differentiation in complex control systems.

Technology Explained Simply
The strain relief housing is a mechanical component that holds the conductor in the connection area and prevents it from being pulled out of the socket due to tension or vibration. This increases the long-term stability of the connection and reduces the risk of contact loss. The socket is designed for conductors with a diameter of 4.5 to 10 mm, ensuring broad compatibility with standard installation cables.

Compatibility and Accessories
The socket 890-123 is compatible with various accessories that enhance and optimize connection security. These include mounting adapters such as 890-310 and 890-311, suitable for free-end connections. Locking latches such as 890-101, 890-111, 890-121, and 890-131 enable tool-based or manual locking of the plug connection. Additionally, protective caps such as 897-2001, strain relief housings such as 890-513, and shield connection plates such as 890-523 are available to further secure the connection. The operating tool 210-719 and the 3-way tool 890-383 support the assembly and disassembly of connections.

Mounting and Installation
Installation is performed by inserting the conductor into the strain relief housing and then into the socket. Locking is achieved via the integrated latch, which can be operated manually or with a tool. The socket is designed for use in enclosures and distribution boxes, with the exact mounting method depending on the plug connector used.

Operational Advantages
The integrated strain relief increases the mechanical stability of the connection and extends the service life of the connection point. The 3-pole configuration enables a compact and efficient connection of multiple conductors in a single component. The white color facilitates identification in complex control systems. Compatibility with various accessories allows application-specific adjustment of connection security.
