Frequently Asked Questions

What is the MERSEN TR17-1/2R fuse used for?

The MERSEN TR17-1/2R is a Class RK5 time-delay cylindrical fuse rated 17.5 A, 250 V AC, 160 V DC. It protects motor circuits, transformers, and other inductive loads from overcurrent while tolerating harmless inrush surges. Common in industrial control panels and power distribution.

What are the specifications of the MERSEN TR-R series fuse?

The MERSEN TR-R series fuse, MPN TR17-1/2R, is a Class RK5 time-delay, non-indicating fuse rated 17.5 A, 250 V AC, 160 V DC. It provides branch-circuit protection with a 200 kA interrupting rating. The cylindrical body fits standard Class RK5 fuse holders.

Where to buy MERSEN TR17-1/2R fuses worldwide?

3G Electric supplies MERSEN TR17-1/2R fuses worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this Class RK5 time-delay fuse.

How to select the correct MERSEN TR-R fuse for a motor circuit?

Select the MERSEN TR-R fuse based on motor full-load current and starting characteristics. The TR17-1/2R (17.5 A) suits motors drawing ~14 A FLA with time-delay to pass inrush. Verify voltage rating (250 V AC / 160 V DC) and ensure Class RK5 rejection clips are used in the fuse holder.
