0253015.V

0253015.V fuses are designed for use in UL and CSA listed 145,000 Class RK1 fusible switches and other high interrupting rating applications. They are a one-piece, time-delay construction available in amperage ratings from 0.125-30A at 600VAC or less. The plug-fuse design allows users to safely and quickly replace old or burnt fuses without tools on the job site without having to open the fuse box. The UL 248-14 listing ensure their quality construction and safe use.

Applications

0253015.V fuses are employed to protect transformers, electrical motors, batteries, control equipment, power converters and other auxiliary equipment. They are also used in lighting systems and other general-purpose applications.

Working Principle

0253015.V fuses are designed to open a circuit automatically when the current through the fuse exceeds a predetermined value. In a DC circuit, these fuses typically have a time-delay action. This means that when the current exceeds a pre-set value (the nominal current), the fuse will open after a pre-determined time. This provides a measure of protection for the circuit since the current should probably have gone down before the fuse opens the circuit.

In AC circuits, the fuse element heats up when the current exceeds the cut-out rating, rapidly melting the contact and opening the circuit. An AC circuit has a constantly changing current, and the fuse must be able to cope with that. The 0253015.V fuse comes with various current ratings which have been designed to cope with the variations in current that may be experienced.

Conclusion

The 0253015.V fuses are a safe and reliable way of protecting equipment, and their one-piece, time-delay construction makes them ideal for use in high interrupting rating applications. Their UL 248-14 listing guarantee their quality construction and safe use, making them the preferred solution for many applications.
