The WAGO 281-623 is a 2-wire fuse terminal from the series 281, designed for use in industrial and electrical installations. The device features a swivel fuse holder and is designed for use with G-fuse inserts with dimensions ¼" x 1¼". The terminal is without fault indication and allows secure mounting on support rails with dimensions 35 x 15 mm and 35 x 7.5 mm. The housing colour is grey, ensuring good visibility in standard installations.

Applications
The fuse terminal 281-623 is suitable for applications requiring a reliable and quick connection of conductors with a fuse. It is commonly used in enclosures, control systems, and distribution units where safe current interruption is necessary in case of overload or short circuit. The combination of a swivel holder and CAGE CLAMP® technology simplifies installation and maintenance, especially in tight or hard-to-reach areas.

Functions and Equipment in Detail
A central feature of the terminal is the CAGE CLAMP® technology, which enables a universal connection for various types of conductors. The cage spring ensures a secure contact without requiring pre-treatment of the conductors. This eliminates the need for crimping wire end ferrules, reducing installation time and error susceptibility. The terminal is suitable for conductor cross-sections from 0.08 mm² to 4 mm², with the exact capacity depending on the conductor type. Conductor stripping lengths of 9 to 10 mm are required for connection.

Technology Explained Simply
The CAGE CLAMP® technology operates with a spring-loaded cage structure that securely encloses the conductor and ensures a stable electrical contact. The spring force maintains the contact even under vibration or temperature fluctuations. The swivel design of the fuse holder allows for easy installation and alignment of the fuse, making the installation process more efficient. The terminal is designed for use on standard support rails, enabling universal application in various enclosure configurations.

Compatibility and Accessories
The terminal is compatible with support rails of dimensions 35 x 15 mm and 35 x 7.5 mm, ensuring broad applicability in different enclosure systems. Available accessories include various support rails, labelling systems such as the WMB multi-labelling system, and tools such as the actuation tool 210-657 or the plug-in conductor bridge 249-126. These components support installation and labelling of the terminal in the enclosure.

Mounting and Installation
Mounting is done by clipping the terminal onto the support rail. The required stripping length of 9 to 10 mm is provided in the conductors to ensure a secure contact. The CAGE CLAMP® technology allows insertion of the conductor without additional tools or pre-treatment. The fuse is inserted into the swivel holder, with positioning facilitated by the swivel mechanism. The terminal is intended for use in enclosed enclosures, with no specific environmental conditions such as humidity or temperature specified.

Advantages in Operation
The terminal offers maintenance-free operation thanks to the CAGE CLAMP® technology, which requires no additional measures such as crimping or soldering. The swivel design of the fuse holder simplifies installation and maintenance, especially during frequent maintenance tasks. Compatibility with various support rails and support from accessories such as labelling systems increases flexibility and clarity in installation.
