Weidmüller 1010000000 WPE 2.5 earthing terminal 2.5 mm² screw terminal direct mounting content_copy

The Weidmüller terminal block WPE 2.5 is an earthing terminal designed for direct mounting, intended for the secure connection of protective conductors to the mounting base (earth). It serves as a reliable connection point for protective conductors with a cross-section of 2.5 mm² in industrial and electrical engineering applications. The terminal is made of hardened steel to withstand mechanical stress and features tin-plated copper to ensure optimal electrical conductivity. The design allows for simple and quick mounting directly onto the base without additional fastening elements.

Applications

The WPE 2.5 is used in electrical installations and machine building where a firm and permanent earth connection is required. It is particularly suitable for systems requiring a secure equipotential bonding connection, such as in enclosures, machine controls, or industrial devices. Direct mounting onto the mounting base reduces the number of required connection elements and increases the reliability of earthing.

Functions and Equipment in Detail

The terminal features a screw connection that enables a secure and durable connection with the protective conductor. The hardened steel material ensures high mechanical strength, while the tin-plated copper conductor strip provides low electrical resistance and thus efficient conductivity. The terminal is designed for use in industrial environments where high loads and permanent electrical conductivity are required.

Technology Explained Simply

The terminal operates on the principle of direct earth connection: the protective conductor is connected via a screw connection to the metallic mounting base, which serves as the earthing point. The use of hardened steel ensures that the terminal maintains its shape even under mechanical stress, such as vibrations or pulling forces. The tin plating on the copper prevents oxidation and corrosion, ensuring long-term stability of the electrical connection.

Compatibility and Accessories

Various accessories are available to complement and label the terminal, including identification carriers such as the BZT 1 WS 10/5, markers such as the SCHT 7 or ZGB 15, and end plates such as the WAP 2.5-10. These elements support identification and structuring of the installation, especially in complex enclosures. Additionally, labelling options such as WS 12/5 MM or DEK 5/5 MC NE are available to enable clear marking of the terminals. Combining with rail holders such as the WEW 35/2 or partition panels such as the WTW EN supports orderly mounting and structuring within the enclosure.

Mounting and Installation

The WPE 2.5 is mounted directly onto the metallic mounting base, with the screw connection securely fixing the protective conductor. Installation is performed without additional holders or fastening elements, which speeds up the process and reduces the number of required components. The terminal is designed for use in enclosures and industrial devices where a quick and secure earth connection is required.

Advantages in Operation

The terminal provides a reliable and durable earth connection, ensured by the material combination of hardened steel and tin-plated copper. Direct mounting reduces the number of required connection elements and increases installation safety. The use of marking and end accessories enables clear structuring and identification of the installation, simplifying maintenance and servicing. The terminal is suitable for use in industrial environments with high mechanical and electrical requirements.
