Product Description

The MERSEN TRS-R Series Class RK5 Time-Delay Cylindrical Fuse (MPN TRS1/2R) is a 500 mA, non-indicating fuse rated for 600 V AC and 600 V DC. This fuse is designed for overcurrent protection in industrial electrical systems, supporting time-delay operation to accommodate inrush currents.

Frequently Asked Questions

What is a MERSEN TRS-R time-delay fuse used for?

The MERSEN TRS-R Class RK5 time-delay fuse protects motor circuits and equipment with high inrush currents. It handles temporary overloads without nuisance opening, making it suitable for pumps, compressors, and conveyors in industrial plants.

What are the specifications of the MERSEN TRS1/2R fuse?

The MERSEN TRS1/2R is a Class RK5, TRS-R series, time-delay fuse rated 500 mA, 600 V AC and 600 V DC. It is non-indicating, cylindrical, and designed for branch-circuit protection where time-delay is required.

Where to buy MERSEN TRS1/2R fuses worldwide?

3G Electric supplies MERSEN TRS1/2R fuses worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for a quote and lead time on this Class RK5 time-delay fuse.

How to select the right MERSEN TRS-R fuse for a motor circuit?

Select a MERSEN TRS-R fuse based on motor full-load current and starting characteristics. The time-delay feature allows temporary overloads. Verify voltage rating (600 V AC/DC) and ensure the interrupting rating meets system fault current.
