Frequently Asked Questions

What is a MERSEN TR-R TR3/10R fuse used for?

The MERSEN TR-R TR3/10R is a 300 mA, 250 V AC/DC time-delay fuse used to protect motor circuits, transformers, and lighting loads from overcurrent. Its time-delay characteristic allows harmless inrush currents without nuisance opening, making it suitable for industrial control panels and power distribution.

What are the specifications of the MERSEN TR3/10R fuse?

The MERSEN TR3/10R is a Class RK5, TR-R series, time-delay, non-indicating fuse rated 300 mA at 250 V AC and 250 V DC. It is a cylindrical fuse with a compact design for branch-circuit protection. The manufacturer part number is TR3/10R.

Where to buy MERSEN TR3/10R fuses worldwide?
