Frequently Asked Questions

What is a MERSEN TRS20R fuse used for?

The MERSEN TRS20R is a Class RK5, time-delay cylindrical fuse rated 20 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and other inductive loads from overcurrent and short circuits, allowing harmless inrush currents without nuisance opening.

What are the specifications of the MERSEN TRS20R fuse?

The MERSEN TRS20R is a Class RK5, time-delay, non-indicating fuse rated 20 A, 600 V AC and 300 V DC. It belongs to the TRS-R series (MPN TRS20R). Its cylindrical body and time-delay characteristic suit motor and transformer protection.

Where to buy MERSEN TRS20R fuses worldwide?
