The WAGO service terminal block type 224-201 is a component of series 224, specifically designed for use in installation systems and home automation applications. It serves as a connection element between wires and enables a secure, mechanical and electrical connection. The terminal block is designed for use in electrical installations where reliable contact of conductors with a cross-section of up to 2.5 mm² is required. The grey version is intended for use in standard installations, where the terminal block is suitable for all types of conductors on both the lighting side and the installation side.

Service terminal block

The terminal block is designed as a service terminal block, meaning it is intended for use in installations where maintenance, inspection or wiring changes may be required. The double-sided actuators allow for easy and secure opening and closing of the terminal block without requiring additional tools. This simplifies installation and maintenance in operation, particularly in complex systems where frequent changes or repairs are necessary.

Applications

The terminal block is intended for use in electrical installations, particularly in home automation areas where flexible and maintainable wiring is required. It is suitable for connecting wires with a cross-section of 0.5 to 2.5 mm², with the maximum allowable cross-section being 2.5 mm². The terminal block is designed for an ambient temperature up to 60 °C, making it suitable for use in indoor environments and enclosed switch cabinets. Use in areas with higher temperatures or outdoors is not intended.

Functions and equipment in detail

The terminal block features a double-sided actuator arrangement, enabling simple and quick operation. The actuators are designed to be opened and closed with a simple press, providing a mechanical locking of the conductors. The terminal block is suitable for all types of conductors, meaning it can be used with both bare and insulated wires. The contact surface is dimensioned to ensure a secure electrical connection even with different conductor cross-sections.

Technology explained simply

The terminal block operates on the principle of pressure clamp technology, where conductors are pressed into a contact zone by a pressure mechanism. The double-sided actuators allow the terminal block to be operated from both sides, which is advantageous in complex wiring applications. The maximum allowable ambient temperature of 60 °C is an important parameter, as it defines the thermal load capacity of the terminal block. If the ambient temperature exceeds this value, the functionality of the terminal block may be impaired. The terminal block is not designed for use in explosive environments or in environments with aggressive chemicals.

Compatibility and accessories

The terminal block is part of WAGO’s series 224 and can be combined with other components of this series. Suitable accessories offered in the product line include the filling syringe 249-130 with 20 ml Alu-Plus contact paste. This paste can be used to improve contact quality and reduce oxidation effects when connecting wires. The use of contact paste is optional and depends on the requirements of the specific installation.

Installation and mounting

The terminal block is mounted in the usual way in switch cabinets or on mounting plates. The terminal block is placed in the designated position and the wires are inserted into the clamp opening. The actuator is then activated to lock the wires in place. The double-sided operation allows the terminal block to be mounted even in confined spaces or in complex wiring arrangements. No additional tools are required to operate the terminal block.

Advantages in operation

The terminal block provides a quick and secure connection of wires, reducing installation time. The double-sided operation facilitates maintenance and inspection, as the terminal block is accessible from both sides. The suitability for all types of conductors increases flexibility during installation. The maximum allowable ambient temperature of 60 °C ensures reliable operation in typical indoor installations. The terminal block is suitable for use in home automation systems and electrical installations where maintainable and flexible wiring is required.
