Product Description

The MERSEN Class RK5 Fuse (SKU 3G-OTH-28773) is a TR-R Series, Time-Delay, Non-Indicating cylindrical fuse rated at 2.25 A, 250 V AC, and 250 V DC (MPN TR2-1/4R).

Frequently Asked Questions

What is the MERSEN TR2-1/4R fuse used for?

The MERSEN TR2-1/4R is a Class RK5 time-delay cylindrical fuse rated 2.25 A at 250 V AC/DC. It protects motor circuits, transformers, and lighting systems from overcurrent while tolerating harmless inrush surges. Common in industrial control panels and HVAC equipment.

What are the specifications of the MERSEN TR2-1/4R fuse?

This MERSEN TR-R series fuse has a 2.25 A current rating, 250 V AC and 250 V DC voltage rating, and a non-indicating design. It is a Class RK5 time-delay cylindrical fuse with manufacturer part number TR2-1/4R. The time-delay feature handles temporary overloads without nuisance opening.

Where to buy MERSEN TR2-1/4R fuses worldwide?

3G Electric supplies MERSEN TR2-1/4R fuses worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time. We source and deliver this MERSEN fuse to any country.

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

Select the MERSEN TR-R fuse by matching voltage (250 V AC/DC) and current rating (2.25 A) to your circuit. Ensure the Class RK5 time-delay characteristic suits motor or transformer starting surges. Verify physical dimensions fit your fuse holder. Consult MERSEN datasheets for coordination with upstream protection.
