The WAGO 243-304 is a MICRO connection terminal block designed for connecting up to four individual conductors in electrical installations. It serves as a compact and reliable solution for use in connection boxes, particularly in applications such as home communication systems, alarm systems, doorbell systems, and similar systems. The terminal block is finished in light grey and enables secure connection of solid conductors with a cross-section of 0.6 to 0.8 mm². The maximum number of connectable conductors is four, and connections with conductors of different cross-sections within the specified range are possible. When exclusively using conductors with a diameter of 0.5 mm (equivalent to AWG 24) or 1.0 mm (equivalent to AWG 18), connection is also possible, increasing the flexibility of the terminal block.

Applications

The terminal block is intended for use in low-voltage installations, particularly in areas where a compact and secure connection of multiple conductors within a box is required. Typical application scenarios include the installation of home communication systems, intercom and doorbell systems, as well as alarm systems. The terminal block is suitable for connecting solid conductors, with dimensions and maximum current load rated to meet the requirements of such systems.

Functions and Equipment in Detail

The WAGO 243-304 enables the connection of four individual conductors within a single terminal block, minimizing space requirements within the box. The terminal block is designed for a conductor cross-section of 0.6 to 0.8 mm², with conductor dimensions specified according to a diameter of 0.8 mm. The maximum operating voltage is 100 V, and the maximum current load is 6 A. The required stripping length for the conductors is 5 to 6 mm, ensuring a secure and reliable connection. The terminal block is manufactured in light grey, allowing it to blend visually into standard installations.

Technology Explained Simply

The MICRO connection terminal block operates on the principle of a terminal block, where conductors are inserted into the block and held securely by a pressure mechanism (e.g., screw or spring). The block is designed to connect four individual conductors simultaneously, enabling multiple connections within a single component. The connection is achieved through a solid contact, ensured by the mechanical tension between the conductors and the terminal block. The terminal block is designed for use with solid conductors, and the stripping length of 5 to 6 mm ensures that the conductors are fully seated in the block, creating a reliable electrical contact.

Compatibility and Accessories

The terminal block is compatible with various accessories that facilitate mounting and labeling. These include, for example, the 4-way mounting adapter orange (item 243-112) and the 6-way mounting adapter orange (item 243-113), which enable secure mounting of the terminal block in the box. Additionally, self-adhesive labeling strips (item 210-332/575-103) are available to support clear identification of individual conductor connections. These accessories are optional and serve to optimize installation and maintenance.

Mounting and Installation

The terminal block is mounted in a connection box, where it is inserted into the designated opening. Mounting is achieved either through the integrated spring mechanism or via additional mounting adapters, ensuring secure fixation. The conductors are inserted into the terminal block with a stripping length of 5 to 6 mm and secured by the pressure mechanism. After installation, the connection is visually inspectable, and correct insertion of the conductors must be ensured.

Advantages in Operation

The terminal block offers a compact and reliable connection solution that minimizes space requirements within the box. The ability to connect up to four conductors in a single terminal block reduces the number of required components and simplifies installation. The maximum current load of 6 A and operating voltage of 100 V are sufficient for most applications in home installations. The light grey color ensures visual harmony with standard installations. The terminal block is designed for use with solid conductors, ensuring a stable and long-lasting connection.

The product is delivered in a pack of 100 pieces, making the WAGO 243-304 suitable for series installations and larger projects. The terminal block is designed for use in low-voltage installations and meets the requirements for safety and reliability in electrical installations.
