Product Description

The MERSEN TRS-R Series TRS50R is a Class RK5 time-delay cylindrical fuse rated at 50 A, 600 V AC and 300 V DC. This non-indicating fuse is designed for overcurrent protection in industrial electrical systems, sourced and supported by 3G Electric across 14 industrial departments with specialist expertise in controls.

Frequently Asked Questions

What is the MERSEN TRS50R fuse used for?

The MERSEN TRS50R is a Class RK5 time-delay cylindrical fuse used for overcurrent protection in industrial motor circuits, lighting panels, and distribution equipment. Its 50 A rating and 600 V AC / 300 V DC capacity make it suitable for branch-circuit protection where high inrush currents occur.

What are the specifications of the MERSEN TRS50R fuse?

The MERSEN TRS50R is a Class RK5, TRS-R Series, time-delay, non-indicating fuse rated 50 A, 600 V AC, and 300 V DC. It is a cylindrical fuse with the manufacturer part number TRS50R. These specifications ensure reliable performance in industrial overcurrent protection applications.

Where to buy MERSEN TRS50R fuses worldwide?

You can source the MERSEN TRS50R fuse 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 source and deliver this fuse to your location.

How to select the correct MERSEN TRS50R fuse for an application?

To select the MERSEN TRS50R, verify your circuit voltage does not exceed 600 V AC or 300 V DC and that the continuous load is below 50 A. The time-delay characteristic handles motor-starting inrush. Always consult the manufacturer's data sheet for coordination with upstream devices and ensure proper Class RK5 rejection clips are used.
