Product Description

The MERSEN TRM Series is a time-delay cylindrical fuse, specifically a midget fuse rated at 4 A and 250 V AC. It features a non-indicating design with dimensions of 13/32 in x 1 1/2 in, identified by manufacturer part number TRM4.

Frequently Asked Questions

What is the MERSEN TRM4 fuse used for?

The MERSEN TRM4 is a time-delay midget fuse used to protect industrial control circuits, motors, and transformers from overloads and short circuits. Its 4 A rating and 250 V AC capacity make it suitable for panel boards and equipment requiring reliable overcurrent protection in manufacturing and process industries.

What are the specifications of the MERSEN TRM4 fuse?

The MERSEN TRM4 is part of the TRM Series, rated at 4 A and 250 V AC. It is a non-indicating, time-delay cylindrical fuse with dimensions of 13/32 in x 1 1/2 in. The manufacturer part number is TRM4, and it is designed for midget fuse applications.

Where to buy MERSEN TRM4 fuses worldwide?

You can source MERSEN TRM4 fuses through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine MERSEN components for industrial maintenance and OEM needs.

How to select the correct MERSEN TRM series fuse for an application?

To select the correct MERSEN TRM series fuse, match the voltage (250 V AC) and current rating (4 A for TRM4) to your circuit requirements. Ensure the time-delay characteristic suits motor or transformer inrush currents. Verify physical dimensions (13/32 in x 1 1/2 in) fit your fuse holder. Consult MERSEN application guides for coordination.
