Product Description

The MERSEN AJT Series is a Class J, time-delay cylindrical fuse with a 6.25 A rating, 600 V AC, and 500 V DC (MPN AJT6-1/4N). This industrial fuse is designed for overcurrent protection in electrical circuits.

Frequently Asked Questions

What is the MERSEN AJT Series fuse used for?

The MERSEN AJT Series fuse (MPN AJT6-1/4N) is a Class J, time-delay cylindrical fuse rated 6.25 A, 600 V AC, and 500 V DC. It provides overcurrent protection in industrial electrical circuits, such as motor control centers, panelboards, and branch circuits, where time-delay characteristics help avoid nuisance openings during startup surges.

What are the specifications of the MERSEN AJT6-1/4N fuse?

The MERSEN AJT6-1/4N is a Class J, cylindrical-body, time-delay fuse rated 6.25 A, 600 V AC, and 500 V DC. It is part of the AJT series from MERSEN. Key specs include a compact cylindrical body for space-constrained installations and a time-delay feature that handles temporary inrush currents without blowing.

Where to buy MERSEN AJT6-1/4N fuses worldwide?

3G Electric supplies the MERSEN AJT6-1/4N fuse worldwide. As a global industrial equipment distributor established in 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this Class J, 6.25 A, 600 V AC fuse to any country.

How to select the right MERSEN AJT fuse for an application?

To select the correct MERSEN AJT fuse, match the voltage rating (600 V AC or 500 V DC) and current rating (6.25 A) to your circuit requirements. The time-delay characteristic suits inductive loads like motors. Ensure the Class J rejection-style holder is used for proper fit. Consult a qualified engineer for coordination with upstream protection devices.
