Miniature cylindrical glass fuse 6.3x32 F 630 mA/250V 006710070

Safety and protection of electrical installations

Fuse links are a basic element protecting electrical installations against overload and short circuit. This miniature cylindrical insert, made of glass, is designed to protect circuits with a voltage of up to 250V. Its compact dimensions (6.3x32 mm) allow for use in a wide range of devices and installations. It is an element that – although small – is crucial for the safety of use and reliability of operation.

Characteristics and application

A fuse with F characteristic (fast) is ideal for protecting circuits sensitive to rapid changes in current, such as electronic systems or delicate receivers. The fast response to overvoltages minimizes the risk of damage to connected devices. The use of a glass body ensures good visibility of the blown element, making it easier to identify the problem. It is worth remembering that these fuses are not intended for protecting circuits with motors or other devices generating high surge currents – in such cases, a fuse with C or D characteristic would be more suitable.

Specification and selection of the appropriate value

Available in two current values: 630 mA (3.15A) and 4A, allowing for adaptation to specific installation needs. Choosing the right current value is crucial for the correct operation of the protection – too low a value will cause the circuit to switch off frequently, and too high a value – may not react in time in the event of a failure. It is worth consulting a specialist to select the optimal value for a given application. These fuses are manufactured by the renowned company ETI POLAM, which guarantees high quality workmanship and compliance with applicable standards.
