Product Description

The MERSEN TRM Series is a time-delay cylindrical fuse, specifically a midget fuse rated at 300 mA and 250 V AC. It features a 13/32 in x 1 1/2 in non-indicating design, identified by manufacturer part number TRM3/10.

Frequently Asked Questions

What is the MERSEN TRM3/10 fuse used for?

The MERSEN TRM3/10 is a time-delay midget fuse rated 300 mA at 250 V AC. It protects industrial control circuits, instrumentation, and small motor loads from overcurrent while tolerating harmless inrush surges. Its 13/32 in x 1 1/2 in non-indicating body fits standard midget fuse holders.

What are the specifications of the MERSEN TRM series fuse?

The MERSEN TRM series fuse is a time-delay midget type rated 300 mA and 250 V AC. It has a 13/32 in x 1 1/2 in non-indicating cylindrical body. The manufacturer part number is TRM3/10. It is designed for overcurrent protection in circuits where temporary current spikes occur.

Where to buy MERSEN TRM3/10 fuses worldwide?

3G Electric supplies the MERSEN TRM3/10 fuse to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial sourcing partner, we provide genuine MERSEN TRM series fuses with reliable lead times. Contact us for a quote and delivery options.

How to select the right MERSEN TRM series fuse for a circuit?

To select the correct MERSEN TRM series fuse, match the voltage rating (250 V AC) and current rating (300 mA) to your circuit requirements. Ensure the interrupting capacity exceeds available fault current. The time-delay characteristic suits loads with inrush, such as transformers or motors. Verify physical size (13/32 in x 1 1/2 in) fits your holder.
