The WAGO 2273-203 is a COMPACT connection terminal block, specifically designed for secure and reliable connection of single-core conductors with a maximum cross-section of 2.5 mm². The product enables the connection of three conductors in a compact design, suitable for use in industrial and electrical installations. The housing is transparent, and the cover is orange, allowing for easy visual identification and maintenance. The maximum ambient temperature is 60 °C (T60), permitting use in environments with moderate thermal loads.

Applications

The terminal block is intended for use in electrical installations, particularly in areas where a compact, robust, and secure connection of conductors is required. It is suitable for applications in machine building, automation technology, and electrical installation. The connection terminal block is frequently used in enclosures, control systems, and distributors, where quick and secure conductor mounting is necessary.

Functions and Equipment in Detail

The terminal block is designed for single-core conductors, with a maximum cross-section of 2.5 mm². The connection is made via a terminal block that can connect three conductors simultaneously. The transparent housing allows for visual inspection of the connection, while the orange cover provides clear optical identification. The terminal block is designed for ambient temperatures up to 60 °C, ensuring safe operation in typical industrial environments.

Technology Explained Simply

The COMPACT connection terminal block operates on the principle of a terminal block, where conductors are inserted into the block and secured by a screw or pressure mechanism. The block is designed to ensure a secure electrical connection without requiring additional tools or special mounting procedures. The transparent housing allows for easy inspection of the connection, while the orange cover provides clear optical identification.

Compatibility and Accessories

Compatible accessories include the filling syringe 249-130 with 20 ml Alu-Plus contact paste, which can be used to improve contact quality. The mounting adapter 2273-500 is suitable for single-row 14 mm and double-row 18.5 mm terminal blocks and enables secure mounting. Additionally, Gelboxes from series 221 are available, which can accommodate up to size 2 terminal blocks with 4 mm² conductors and offer IP68 protection, making them suitable for use in damp or contaminated environments.

Mounting and Installation

Mounting of the terminal block is done by simply inserting the conductors into the terminal block and tightening with an appropriate tool. The terminal block is designed to ensure a secure connection without requiring additional tools or special mounting procedures. The transparent housing allows for easy visual inspection of the connection, while the orange cover provides clear optical identification.

Operational Advantages

The terminal block offers a compact design, saving space in the enclosure. The secure connection of three conductors in a single block reduces the number of required components and simplifies installation. The transparent housing allows for easy visual inspection of the connection, while the orange cover provides clear optical identification. The maximum ambient temperature of 60 °C ensures safe operation in typical industrial environments.
