The WAGO 285-135 is a 2-conductor pass-through terminal block designed for use in industrial electrical installations. It enables secure and reliable connection of two conductors with a cross-section up to 35 mm². The terminal block is part of the POWER CAGE CLAMP series and features a robust construction designed for high mechanical loads and long-term electrical conductivity. The grey colour corresponds to the standard version for this series and serves for visual differentiation within control systems. The terminal block is exclusively intended for mounting on a support rail in 35 x 15 mm format, enabling integration into standard enclosures and distribution boxes.

Applications

The 2-conductor pass-through terminal block 285-135 is used in industrial electrical engineering, particularly in enclosures, distribution boxes, and control systems. It is used for connecting conductors with a cross-section from 6 to 35 mm², where the maximum cross-section of 35 mm² represents the upper limit for use of this terminal block. The terminal block is suitable for use in systems with high electrical loads, as it ensures a stable and durable connection. The side labelling slots allow for clear identification of connections, facilitating maintenance and servicing of systems.

Functions and Equipment in Detail

The terminal block features a pass-through design, where two conductors are connected at a single connection point. The connection is made via a clamp jaw, which secures the conductor using a screw mechanism or a clamp lever (depending on the model). The side labelling slots are designed for mounting labelling plates, which serve to identify the connections. These labelling slots are designed for plates with a height of 5 to 17.5 mm, supporting a variety of labelling systems such as WMB multi-labelling or inline labels. The terminal block is not intended for use without a support rail, but must be mounted on a 35 x 15 mm support rail.

Technology Explained Simply

The POWER CAGE CLAMP technology ensures a secure and durable connection of the conductors. The terminal block operates with a clamp lever that fixes the conductor in a clamp jaw. The clamp jaw is designed to securely enclose the conductor cross-section from 6 to 35 mm² and ensure optimal electrical contact surface. The grey colour of the terminal block is a visual feature used in industrial electrical engineering to differentiate between various terminal types or functions. Mounting is done on a support rail, typically made of galvanised steel, which ensures the mechanical stability of the entire circuit.

Compatibility and Accessories

The terminal block is compatible with various support rails in 35 x 15 mm format, including galvanised steel support rails and copper support rails. Suitable accessories include labelling systems such as WMB multi-labelling in various colours (yellow, grey, blue, red, purple, light green) as well as inline labelling strips. Additionally, warning covers with a black lightning bolt are available for marking hazardous voltages. Test adapters for test plugs with a diameter of 4 mm are also available to check the electrical function of the terminal block. The terminal block does not feature an integrated protection rating or IP rating, as it is intended for use in enclosed enclosures.

Mounting and Installation

Mounting of the terminal block is done on a support rail in 35 x 15 mm format, where the terminal block is placed onto the rail using an integrated clip or clamp jaw. The connection of conductors is made by inserting the conductor into the clamp jaw and then tightening the clamp lever. The side labelling slots can be fitted with labelling plates to clearly identify the connections. Mounting requires no additional tools, except a screwdriver or clamp lever tool if necessary. The terminal block is not intended for outdoor use, as it does not have special weather resistance or protection rating.

Advantages in Operation

The 2-conductor pass-through terminal block 285-135 provides a reliable and durable connection for conductors with a cross-section up to 35 mm². The side labelling slots facilitate identification of connections, speeding up maintenance and servicing of systems. Mounting on a support rail enables standardised and modular installation, increasing flexibility in planning and expanding control systems. The POWER CAGE CLAMP technology ensures a stable electrical connection that remains secure even under mechanical stress. The terminal block is designed for use in industrial environments where high electrical loads and mechanical stresses occur.
