General
DIN rail width	35 mm

The snap mounting 1722V9010 from Gossen is a specially developed mounting accessory for plug-in current transformers of type ASK 31.3 and WSK30. It is designed for secure and quick mounting of these current transformers on 35 mm DIN rails, which comply with the standard DIN EN 50522. This mounting solution enables tool-free installation and removal, thereby making the installation and maintenance of current transformers in enclosures or distribution boxes more efficient. The snap mounting is designed for use in industrial and electrical installations where stable and reliable mounting of measuring and switching devices is required.

DIN rail mounting
The snap mounting is specifically designed for mounting on 35 mm DIN rails, which are standard in electrical engineering for securing components in enclosures. The DIN rails comply with the standard DIN EN 50522, which defines the dimensions and mechanical requirements for such profiles. The mounting engages into the groove of the DIN rail and secures the connected device via a snap mechanism that ensures a firm connection without requiring additional fastening elements such as screws or clamps.

Compatibility with current transformers
The snap mounting 1722V9010 is exclusively intended for mounting the plug-in current transformers ASK 31.3 and WSK30. These current transformers are used in electrical installations to measure and monitor current levels. The mounting is designed to precisely accommodate the specific dimensions and mounting interfaces of these current transformers, ensuring secure and correct positioning. Use with other devices or current transformer types is not intended and may result in insecure mounting.

Function and mounting
Mounting is performed by simply inserting the snap mounting into the DIN rail and then plugging the current transformer into the mounting. The snap mechanism ensures the device is securely held and cannot accidentally disengage. Removal is achieved by releasing the snap lock, allowing the device to be removed. This process requires no tools and is therefore particularly suitable for maintenance and replacement work. The snap mounting is made from a robust, electrically insulating material that meets the requirements for use in electrical installations.

Use in electrical engineering
The snap mounting is typically used in enclosures, distribution boxes, or other electrical distribution units where current transformers are mounted for measuring and monitoring electrical circuits. The use of DIN rails enables a modular and structured arrangement of components, facilitating maintenance and expansion of the installation. The snap mounting supports this structuring by enabling quick and secure mounting of current transformers without requiring additional mounting aids.

Advantages in operation
The tool-free mounting and removal reduce the time required for installation and maintenance of current transformers. The secure mounting minimizes the risk of displacement or loosening of devices during operation, increasing the reliability of measurements and the safety of the installation. Compatibility with the specific current transformer types ASK 31.3 and WSK30 ensures a precise fit and prevents incorrect mounting. Use in installations with DIN EN 50522-compliant DIN rails provides a standardized and verified mounting solution.

Technology explained simply
The snap mounting uses a mechanical locking mechanism that functions through elastic deformation of a plastic element. When inserted into the DIN rail, the element is slightly bent to engage into the groove. When the current transformer is inserted, the lock is activated and holds the device securely. The material selection ensures electrical insulation and mechanical stability, which is essential for use in electrical installations. The design is engineered to safely support the weight of the current transformer without deforming or loosening.

Compatibility and accessories
The snap mounting is exclusively intended for current transformers ASK 31.3 and WSK30. These current transformers are plug-in types specifically designed for mounting on DIN rails. The mounting is not suitable for other current transformers or components. There are no additional accessories specifically designed for this snap mounting. Mounting is performed directly onto the DIN rail without additional adapters or brackets.

Mounting and installation
Installation is performed by inserting the snap mounting into the 35 mm DIN rail. Subsequently, the current transformer ASK 31.3 or WSK30 is plugged into the mounting, whereupon the snap lock activates automatically. Removal is achieved by pressing or flipping the lock, allowing the current transformer to be removed. The mounting requires no tools and can be performed even in confined spaces within enclosures. The mounting is designed for use in electrical installations that use DIN EN 50522-compliant DIN rails.

Advantages in operation
The tool-free mounting reduces installation time and simplifies maintenance work. The secure mounting prevents displacement or loosening of current transformers during operation, increasing the reliability of measurements. The specific fit for current transformers ASK 31.3 and WSK30 ensures correct mounting and avoids misalignment. Use in installations with DIN EN 50522-compliant DIN rails provides a standardized solution widely used in electrical engineering.
