Product Description

The MERSEN A2D-R Series Class RK1 Time-Delay Cylindrical Fuse (MPN A2D8R) is an 8 A, 250 V AC and 250 V DC indicating fuse. This industrial fuse is designed for overcurrent protection with time-delay characteristics.

Frequently Asked Questions

What is the MERSEN A2D8R fuse used for?

The MERSEN A2D8R is a Class RK1 time-delay fuse used for overcurrent protection in industrial electrical circuits. Its 8 A rating and 250 V AC/DC capability make it suitable for motor circuits, transformers, and other equipment requiring inrush current tolerance. The indicating feature allows quick identification of a blown fuse.

What are the specifications of the MERSEN A2D8R fuse?

The MERSEN A2D8R is a Class RK1, A2D-R Series, time-delay, indicating fuse rated at 8 A, 250 V AC, and 250 V DC. It is manufactured by MERSEN under MPN A2D8R. The time-delay characteristic handles temporary overloads, while the indicating function shows when the fuse has opened.

Where to buy the MERSEN A2D8R fuse worldwide?
