Miniature cylindrical glass fuse 5X20 T 315 MA/250V 006710005

Safety and Protection of Electrical Installations

Miniature cylindrical, glass fuse designed to protect electrical circuits with a voltage of 250V. It is a safety element against the effects of overloads and short circuits, ensuring safe operation of the installation. These types of fuses are widely used in both domestic and industrial installations.

This particular model, with a rated current of 315 mA, is characterized by a time-delay tripping characteristic (denoted as "T"). This means that it allows for short-term exceeding of the rated current without immediate disconnection of the circuit. This is especially important for devices with electric motors or other loads generating high starting currents – allowing them to start freely without unnecessarily blowing the fuse.

It is worth remembering that proper selection of the fuse is crucial to ensure reliable protection. Too small a rated current will cause frequent, unjustified disconnection of the circuit, while too large – may lead to damage to the installation in the event of a failure.

Construction and Application

The fuse has dimensions of 5x20 mm and is made of glass. This size is a standard for miniature cylindrical fuses, ensuring compatibility with a wide range of distribution boards and fuse holders. The glass housing allows for visual control of the fuse status – burnout is easily noticeable by a change in color or damage to the glass tube.

These types of fuses are commonly used to protect:

• Lighting circuits
• Electrical outlets
• Electronic devices
• Alarm systems and monitoring systems
• Controllers and automation systems

Specification and Product Features

The 006710005 fuse from ETI Polam is a high-quality product that meets safety standards. Designed for operation in circuits with a voltage of 250V and a rated current of 0.315A (315mA). The time-delay tripping characteristic makes it ideal for protecting devices generating short-term current surges during startup. Thanks to its compact dimensions (5x20 mm), it is easy to install in standard distribution boards and fuse holders. The package contains 10 pieces of fuse.
