The WAGO connection terminal type 221-615 is a COMPACT connection terminal for use in industrial and electrical installations. It enables secure and quick connection of up to five conductors with a maximum cross-section of 6 mm². The terminal is equipped with operating levers that allow simple and tool-free installation of the conductors. The housing is transparent, facilitating visual inspection of the connection and conductor cross-section during installation and maintenance. The terminal is suitable for all types of conductors, including single- and multi-strand copper wire, and can be used in switchgear, control systems, and distributors.

Applications

The terminal is intended for use in electrical installations indoors, particularly in enclosures, distribution boxes, and control systems. It is suitable for applications requiring a compact, reliable, and quickly installable connection. The maximum ambient temperature is 85 °C (T85), enabling use in environments with moderate thermal load.

Functions and Equipment in Detail

The connection terminal 221-615 features five connection points, each capable of accepting a conductor with up to 6 mm² cross-section. The operating levers allow for easy and quick fastening of the conductors without additional tools. The transparent housing design provides a direct view of the inserted conductors, facilitating inspection of correct connection and detection of wear or damage. The terminal is designed for all common conductor types, including single- and multi-strand copper wire, and ensures a stable electrical connection.

Technology Explained Simply

The terminal operates on the principle of lever locking: when the lever is actuated, the conductor is inserted into the terminal and held securely by a spring-loaded clamping mechanism. The connection is made through direct metallic contact, ensuring low transition resistance and high electrical conductivity. The maximum conductor cross-section of 6 mm² corresponds to a diameter of approximately 2.5 mm, which is sufficient for many industrial and household applications. The temperature resistance up to 85 °C ensures reliable operation even under increased thermal load, as may occur in enclosed enclosures.

Compatibility and Accessories

The terminal is part of the WAGO Series 221 and can be combined with other products in this series to create modular switchgear systems. Suitable accessories include mounting adapters such as items 221-510, 221-510/000-006, and 221-510/000-053, which enable secure mounting on rails or other substructures. Additionally, insulated bridges such as 221-941/000-006, 221-942/000-006, 221-941, and 221-942 are available to create electrical connections between adjacent terminals. For processing of wire leads, accessory 207-1432, a gel box for wire leads with branch and gel, is available, supporting insulation and protection of conductor ends.

Mounting and Installation

Installation is tool-free and performed by actuating the levers. Conductors are inserted into the respective opening and the lever is pressed down, securing the conductor. The transparent housing design allows visual verification of correct insertion and fastening. Installation is carried out in enclosed switchgear, ensuring the ambient temperature does not exceed 85 °C.

Advantages in Operation

The terminal provides a fast and reliable connection without tools, reducing installation time and minimizing error potential. The transparent design facilitates maintenance and inspection, as the connection is visually inspectable. Compatibility with other products in Series 221 enables flexible and modular system design. Suitability for all conductor types and temperature resistance up to 85 °C extend the application range in various industrial and electrical installations.
