Miniature cylindrical glass fuse 5X20 T 250 MA/250V 006710042

Professional electronic circuit protection

The miniature cylindrical glass fuse 5x20 T 250mA/250V is a reliable protective component in a compact form, designed for precision electronic applications. Thanks to its time-delay characteristic (T), it is ideal for circuits with variable loads and devices requiring protection against prolonged overcurrent.

Construction and technical parameters

The glass fuse with dimensions 5×20 mm ensures optimal protection while maintaining minimal mounting space. The glass body allows for optical status control - if the fuse blows, the break in the fuse wire is immediately visible. The rated current of 0.25A and voltage of 250V allow for safe operation in typical electronic applications.

The time-delay characteristic (T) reacts more slowly to short-term current surges, protecting circuits from nuisance tripping during device startup. At the same time, it effectively interrupts the circuit during prolonged overcurrent, preventing installation overheating.

Application and compatibility

The product belongs to the Ultra-Quick series by ETI Polam and is used as a protective element in various electronic applications requiring protection against overcurrent.

The IP20 protection rating provides basic resistance to touch and small solid objects, which is sufficient for most indoor applications.
