Product Description

The MERSEN A2D-R Series Class RK1 Time-Delay Cylindrical Fuse (MPN A2D2-1/4R) is a non-indicating fuse rated at 2.25 A, 250 V AC, and 250 V DC. This industrial fuse from MERSEN provides time-delay protection for electrical circuits.

Frequently Asked Questions

What is the MERSEN A2D2-1/4R fuse used for?

The MERSEN A2D2-1/4R Class RK1 time-delay fuse protects industrial electrical circuits from overloads and short circuits. It is commonly used in motor control centers, panelboards, and feeder circuits where inrush currents occur. Its 2.25 A rating and 250 V AC/DC capability suit low-voltage power distribution applications.

What are the specifications of the MERSEN A2D-R fuse?

The MERSEN A2D-R Series fuse (MPN A2D2-1/4R) is a Class RK1, time-delay, non-indicating cylindrical fuse rated at 2.25 A, 250 V AC, and 250 V DC. It provides time-delay protection to accommodate temporary inrush currents without nuisance opening, making it suitable for inductive loads.

Where to buy MERSEN A2D2-1/4R fuses worldwide?
