Product Description

The MERSEN A2D-R Series Class RK1 Time-Delay Cylindrical Fuse (MPN A2D12R) is a 12 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 A2D12R fuse used for?

The MERSEN A2D12R is a Class RK1 time-delay cylindrical fuse used for overcurrent protection in industrial equipment. Its 12 A rating and 250 V AC/DC capability make it suitable for motor circuits, transformers, and other inductive loads where inrush currents occur.

What are the specifications of the MERSEN A2D12R fuse?

The MERSEN A2D12R is a Class RK1, A2D-R Series, time-delay indicating fuse rated at 12 A, 250 V AC and 250 V DC. It provides overcurrent protection with a time-delay characteristic to handle temporary surges without nuisance opening.

Where to buy MERSEN A2D12R fuses worldwide?

3G Electric supplies the MERSEN A2D12R 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 on this Class RK1 time-delay fuse.

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

Select the MERSEN A2D-R fuse based on the circuit's continuous current (12 A for the A2D12R), voltage rating (250 V AC/DC), and the need for time-delay characteristics. Ensure the Class RK1 rejection feature matches the fuse holder to prevent substitution with lower-rated fuses.
