Product Description

The MERSEN TRS125RID is a Class RK5, time-delay blade fuse from the TRS-RID Series, rated 125 A at 600 V AC and 600 V DC. This indicating fuse provides visual status for quick identification of blown circuits, supporting safe maintenance in industrial electrical systems.

Frequently Asked Questions

What is the MERSEN TRS125RID fuse used for?

The MERSEN TRS125RID is a Class RK5 time-delay blade fuse rated 125 A, 600 V AC/DC. It is used for motor circuits, transformers, and other industrial equipment requiring overload protection and short-circuit interruption. The indicating feature allows quick visual identification of a blown fuse, reducing downtime in plant maintenance.

What are the specifications of the MERSEN TRS125RID fuse?

The MERSEN TRS125RID is a Class RK5, TRS-RID series, time-delay blade fuse. It has a current rating of 125 A, voltage rating of 600 V AC and 600 V DC, and includes an indicating function. The manufacturer part number is TRS125RID. It is designed for high-interrupting capacity in industrial power distribution.

Where to buy MERSEN TRS125RID fuses worldwide?

3G Electric supplies the MERSEN TRS125RID fuse worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source and deliver genuine MERSEN components to support your operations.

How to select the correct MERSEN TRS125RID fuse for an application?

To select the MERSEN TRS125RID, verify your circuit voltage does not exceed 600 V AC or DC and the continuous load current is below 125 A. Ensure the fuse class (RK5) matches your fuse holder. For motor starting or transformer inrush, the time-delay characteristic prevents nuisance opening. Consult the TRS-RID series datasheet for coordination.
