The WAGO 2001-1201 is a 2-conductor pass-through terminal block, specifically developed for use in explosion-protected installations of category Ex e II. It is designed for safe and reliable connection of two conductors in industrial electrical installations, particularly in environments where increased safety requirements apply to the electrical connection. The terminal block is finished in grey and allows connection of conductors with a cross-section of 0.25 to 1.5 mm², with an extension to 2.5 mm² possible under certain conditions. The construction ensures a stable and durable connection, meeting the requirements of industrial electrical engineering.

Applications

The terminal block is intended for use in explosion-hazardous areas according to protection type Ex e II. This includes applications in the process industry, chemical industry, petrochemical industry, and other sectors where the risk of explosion due to electrical sparks or overheating exists. The terminal block is suitable for connecting cables in enclosures, control systems, and other electrical installations operated in such environments. Use in non-explosion-hazardous areas is also possible, provided the electrical and mechanical requirements are met.

Functions and Equipment in Detail

The 2-conductor pass-through terminal block enables the parallel connection of two conductors at a single connection point. The terminal block is designed for a conductor cross-section of 0.25 to 1.5 mm², with an extension to 2.5 mm² possible under consideration of the respective installation specifications. The grey colouring serves visual differentiation and is typical for WAGO products in this product line. The terminal block is designed for use in enclosures and control systems, with mounting on standard support rails. The construction ensures a secure and durable connection, meeting the requirements of industrial electrical engineering.

Technology Explained Simply

The terminal block operates on the principle of a pass-through terminal block, where two conductors are connected at a single connection point. The connection is made via a pressure connection, secured by the screw force of the terminal block. The terminal block is designed for use in explosion-hazardous areas according to Ex e II, meaning it meets specific requirements for electrical safety to minimise the risk of explosion caused by electrical sparks or overheating. The protection type Ex e II refers to the protection type enhanced safety, achieved through constructive measures such as limiting surface temperature and avoiding spark generation. The terminal block is designed for use in industrial installations operated in explosion-hazardous areas.

Compatibility and Accessories

The terminal block is compatible with various accessories that extend its functionality. These include comb bridges such as the 2001-433 (1 to 3) or 2001-435 (1 to 5), which enable parallel connection of multiple conductors. Also compatible are plug-in connector strips such as the 2001-554 or test adapters such as the 2009-174, which support maintenance and diagnostics of the installation. Mounting is done on standard support rails, with rails such as 210-112 or 210-115 being suitable. Cover profiles such as the 709-169 or labelling systems such as the 2009-114/000-005 can be used for better identification and structuring of the installation.

Mounting and Installation

Mounting of the terminal block is done on standard support rails with dimensions 35 x 7.5 mm. The terminal block is placed on the rail using a screwdriver or suitable mounting tool and secured. Connection of the conductors is done by inserting the conductors into the terminal opening and then tightening the screw, which activates the pressure connection. Mounting requires no additional tools or special preparations. The terminal block is designed for use in enclosures and control systems, with positioning and cabling required to comply with respective installation regulations.

Advantages in Operation

The terminal block provides a secure and reliable connection, meeting the requirements for use in explosion-hazardous areas. The use of WAGO products ensures high quality and durability. The terminal block is easy to mount and requires no special tools. Compatibility with various accessories allows flexible adaptation to the specific requirements of the installation. The grey colouring facilitates visual identification and structuring of the installation. The terminal block is designed for use in industrial electrical installations, where the connection remains durable and stable.
