Ferraz Shawmut TRS600R Time Delay Fuse 600A RK5

Product Description

The FERRAZ SHAWMUT TRS600R is a cylindrical, Class RK5 time delay fuse rated at 600 amps and designed for electrical circuit protection in demanding commercial and industrial applications. Measuring 13-3/8 inches overall length (OAL) with a 3-1/8 inch diameter, this fuse is constructed with a fiberglass and polyester body for durability. It carries an interrupting rating of 100 kA at DC and 200 kA at AC, making it suitable for high-fault-current environments. Licensed electricians and industrial maintenance technicians are the primary installers of this fuse class.

This fuse is used in motor branch circuits, feeder circuits, and other high-current electrical distribution systems where time delay characteristics are required to ride through normal motor inrush current without nuisance tripping. The Class RK5 rating places it within a standardized fuse class commonly specified in panel schedules and motor control center (MCC) designs for both commercial and industrial facilities.

Key Features

• Class RK5 time delay design accommodates motor inrush current without nuisance tripping
• 600 amp continuous current rating for high-load circuits
• 200 kA AC interrupting rating for high-fault-current protection
• 100 kA DC interrupting rating suitable for DC distribution systems
• Fiberglass and polyester body construction for mechanical durability
• Cylindrical form factor: 13-3/8 inches OAL, 3-1/8 inches diameter

Compatibility

Designed as an OEM-style replacement for Class RK5 cylindrical fuse holders and fusible disconnects rated for 600-amp, high-interrupting-capacity applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing fuses. Verify the fuse holder is rated for the fuse dimensions and current rating before installation. Do not use this fuse as a substitute for a different fuse class without confirming system compatibility.
