Frequently Asked Questions

What is the MERSEN TR4/10R fuse used for?

The MERSEN TR4/10R is a Class RK5, time-delay cylindrical fuse rated 400 mA at 250 V AC/DC. It protects industrial circuits from overloads and short circuits, commonly used in motor control centers, panel boards, and branch circuits where inrush currents occur.

What are the specifications of the MERSEN TR4/10R fuse?

The MERSEN TR4/10R is part of the TR-R series, a Class RK5 time-delay fuse. It has a current rating of 400 mA and a voltage rating of 250 V AC and 250 V DC. It is non-indicating and has a cylindrical body. The manufacturer part number is TR4/10R.

Where to buy MERSEN TR4/10R fuses worldwide?

3G Electric supplies MERSEN TR4/10R fuses worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this fuse to any country.

How to select the correct MERSEN TR4/10R fuse for an application?

To select the MERSEN TR4/10R, verify your circuit's voltage (250 V AC/DC max) and continuous current (400 mA). Ensure the Class RK5 time-delay characteristic matches your load's inrush profile, such as motors or transformers. Always consult the manufacturer's data sheet for coordination and interrupting rating.
