Product Description

The MERSEN A2D-R Series Class RK1 Time-Delay Cylindrical Fuse (MPN A2D25R) is a 25 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 A2D25R fuse used for?

The MERSEN A2D25R is a Class RK1 time-delay cylindrical fuse used for overcurrent protection in industrial equipment. Its 25 A rating and 250 V AC/DC capability make it suitable for motor circuits, transformers, and other inductive loads where inrush current tolerance is required.

What are the specifications of the MERSEN A2D25R fuse?

The MERSEN A2D25R is a Class RK1, A2D-R Series, time-delay indicating fuse rated 25 A at 250 V AC and 250 V DC. It is manufactured by MERSEN under MPN A2D25R. The indicating feature allows visual identification of a blown fuse for faster troubleshooting.

Where to buy MERSEN A2D25R fuses worldwide?

3G Electric supplies the MERSEN A2D25R fuse worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this Class RK1 time-delay fuse to any country.

How to select the correct MERSEN A2D-R fuse for an application?

To select the correct MERSEN A2D-R fuse, match the voltage rating (250 V AC/DC) and current rating (e.g., 25 A for A2D25R) to your circuit requirements. Consider the time-delay characteristic for motor or transformer loads. Always verify the Class RK1 rejection feature prevents substitution with lower-rated fuses.
