Calibrated insert STV D02 Insert D02 25A 002243011

Calibration insert for STV D02 disconnector – a key to the correct operation of the installation

The STV D02 25A calibration insert is an essential element for the proper operation of the STV D02 insulated disconnector with a fuse. It is used to precisely match the protection characteristics to the needs of the electrical installation, ensuring its reliable protection against overloads and short circuits. This is particularly important in installations where selective cooperation with other protective elements, such as overcurrent circuit breakers, is required.

Functionality and application

The calibration insert allows the disconnector to be adapted to different loads, in the range from 2 to 63A (using appropriate fuse links). This means that a single device can be used in various applications, which translates into saving space and costs. Replacing the fuse link is done safely, without the risk of touching live parts. In addition, the disconnector allows for sealing in the open or closed position, which increases safety and control over the installation.

Advantages for the installer and end user

• Versatility: the ability to use with different fuse links (up to 63A) allows you to adapt the protection to specific needs.
• Safety: the fuse link is replaced without the need to disconnect the power supply and the risk of electric shock.
• Selectivity: ensures cooperation with other protective elements, minimizing the risk of unnecessary disconnection of the entire installation in the event of a failure.
• Easy installation: the possibility of connecting the power supply from "above" or "below" facilitates installation in various conditions.
• Possibility of sealing: increases safety and prevents unauthorized changes to settings.
• Compact size: the D02 insert is characterized by small dimensions, which facilitates installation even in tight spaces.
• Durability: made of high-quality materials ensures long-lasting and reliable operation.

It is worth remembering the possibility of using D01-STV D02 reduction inserts if a lower rated current value is required. The STV D02 25A calibration insert is a solid solution for professionals and people who care about the safety and reliability of their electrical installation.
