Miniature cylindrical-glass fuse 5X20 F 4A/250V 006710023

Safety and protection of electrical installations

Miniature cylindrical glass fuse with dimensions 5x20 mm, designed to protect electrical circuits against overload and short circuit. It is a key element ensuring the safe operation of devices and installations in residential, commercial buildings and in industry. Its fast tripping characteristic (F) makes it ideal for protecting delicate electronics and devices sensitive to overvoltage.

Construction and application

The fuse is made of high-quality glass, which ensures its mechanical strength and resistance to external factors. Its compact size allows for mounting in a limited space, which is particularly important in applications where minimizing dimensions is important. The rated current of 4A at a voltage of 250V makes it suitable for protecting circuits with lower power consumption - e.g. lighting, control or electronic systems.

Characteristics and benefits

• Fast reaction: Characteristic F ensures very fast tripping in the event of a short circuit, minimizing the risk of damage to connected devices. This is especially important for sensitive electronic components.
• Versatility: The fuse is compatible with most standard 5x20 mm fuse holders, making it easy to replace and install.
• High reliability: The manufacturer ETI Polam is a guarantee of solid workmanship and durability.
• Markings: Clear markings on the housing make it easy to identify the rated current and voltage, which simplifies the service and replacement process.
• Transparency: The glass housing allows for visual control of the fuse status - burnout is easily noticeable without the need for disassembly.

Installation and replacement

Replacing the fuse is simple and does not require specialized tools. Remember to disconnect the power supply before starting work and use a fuse with identical parameters (rated current and characteristic). Installers will appreciate the ease of use and quick installation, which translates into time savings during project implementation. The end user will gain confidence in the safe operation of the electrical installation thanks to the easy possibility of self-replacing a blown fuse (after disconnecting the power supply!).
