The WAGO 281-611 is a 2-wire fuse terminal block designed specifically for use in industrial and electrical installations. It features a swivelling fuse holder designed for G-fuse inserts with dimensions 5 x 20 mm. The terminal block is finished in grey and is intended for secure and reliable connection of conductors with a cross-section of 0.08 to 4 mm². It is supplied without a fault indicator, meaning that a fuse failure is not visually indicated. The terminal block is suitable for use in enclosures and control systems where a stable and secure electrical connection is required.

Fuse terminal block with swivelling holder enables flexible mounting and easy maintenance. The swivelling fuse holder facilitates the insertion and removal of the fuse, especially in tight mounting conditions. The terminal block is designed for use with G-fuses, which are commonly used in industrial electrical engineering to protect circuits against overloads and short circuits. The connection is made via a mechanical clamp connection, ensuring a secure and durable electrical contact.

Applications include mounting in enclosures, control systems, distribution boxes, and other electrical installations where a secure electrical connection with integrated fuse protection is required. The terminal block is particularly suitable for applications where high reliability and easy handling are prioritized. It is appropriate for use in industrial electrical engineering, building automation, and the machine construction industry.

Functions and features in detail include a swivelling fuse holder that enables easy mounting and maintenance. The terminal block is designed for conductor cross-sections from 0.08 to 4 mm², covering a wide range of cables. The grey finish is standard for industrial applications and ensures good visibility in enclosures. The terminal block is without a fault indicator, meaning that a fuse failure is not optically detectable.

Technology explained simply shows that the terminal block operates via a mechanical clamp connection, where the conductor is inserted into a clamp jaw and secured by a screw or lever. The swivelling fuse holder allows for easy operation, especially in confined spaces. The use of G-fuses with 5 x 20 mm dimensions is standard in industrial electrical engineering and provides a high level of protection.

Compatibility and accessories include use with G-fuses in the 5 x 20 mm format. Compatible accessories available in the range include steel mounting rails (e.g. 210-506, 210-114, 210-115, 210-505), conductor bridges (e.g. 249-126, 210-103), multi-labelling systems (e.g. 793-5501/000-006, 793-501/000-007, 793-501/000-023, 793-5501/000-023), mounting brackets (e.g. 209-106), wire end ferrules (e.g. 216-243), and cross bridges (e.g. 281-402). These components can be used to expand and label the enclosure installation.

Mounting and installation is carried out on standard mounting rails in 35 x 15 mm or 35 x 7.5 mm format, which are available in the accessory range. The terminal block is mounted onto the mounting rail using a mounting lever or screw clamp. The connection of conductors is made by inserting the cable into the clamp jaw and securing it with a lever or screw. Mounting is simple and does not require special tools.

Operational advantages include easy handling, secure connection, and compact design. The swivelling construction of the fuse holder facilitates maintenance and repair. The terminal block is designed for industrial environments and offers high reliability. The use of G-fuses ensures effective circuit protection.

The terminal block is designed for use in electrical installations where a secure electrical connection with integrated protection is required.
