Product Description

The MERSEN A2D20R is a Class RK1 time-delay cylindrical fuse from the A2D-R series, rated for 20 A at 250 V AC and 250 V DC. This indicating fuse is designed for overcurrent protection in industrial electrical systems.

Frequently Asked Questions

What is the MERSEN A2D20R fuse used for?

The MERSEN A2D20R is a Class RK1 time-delay cylindrical fuse rated 20 A at 250 V AC and 250 V DC. It provides overcurrent protection in industrial electrical systems, such as motor control centers and distribution panels, where time-delay characteristics help avoid nuisance tripping from inrush currents.

What are the specifications of the MERSEN A2D20R fuse?

The MERSEN A2D20R is a Class RK1, A2D-R series, time-delay, indicating fuse rated 20 A at 250 V AC and 250 V DC. It features a cylindrical body and visual indication for blown fuse identification. The manufacturer part number is A2D20R.

Where to buy the MERSEN A2D20R fuse worldwide?

3G Electric supplies the MERSEN A2D20R fuse to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this Class RK1 time-delay fuse.

How to select the right MERSEN A2D-R fuse for my application?

To select the correct MERSEN A2D-R fuse, verify the system voltage (250 V AC or DC), continuous current rating (20 A for the A2D20R), and required time-delay characteristics. Class RK1 fuses offer high interrupting capacity and current limitation. Consult the fuse's time-current curve for coordination with upstream devices.
