Mersen TRS2-8/10R Time-delay Fuse 2-1/8A 600V

Product Description

The MERSEN TRS2-8/10R is a time-delay (TD) fuse rated at 2-1/8 amps and 600 volts, classified as Class RK5. Time-delay fuses in this class are designed to withstand brief inrush currents common in motor and transformer circuits without nuisance tripping, while still providing fast, reliable overcurrent protection under sustained fault conditions. This fuse is suited for use in control panels, motor branch circuits, and equipment protection applications where a dual-element design is required. Installation is typically performed by licensed electricians working within NEC guidelines for overcurrent protection.

Class RK5 time-delay fuses like the TRS2-8/10R are commonly specified for residential and light commercial electrical panels, motor starters, HVAC equipment disconnect boxes, and control circuit protection. The 600-volt rating makes this fuse appropriate for use across a wide range of single-phase and three-phase branch circuit applications. Its compact amperage of 2-1/8 amps targets low-current control and motor circuits where precision protection is critical.

Key Features

• Time-delay (dual-element) design tolerates motor inrush without nuisance tripping
• 2-1/8 amp rating for low-current branch circuit and control circuit protection
• 600-volt rating suitable for single-phase and three-phase applications
• Class RK5 classification ensures interchangeability with standard RK5 fuse holders
• Compact form factor for use in tight panel and disconnect box installations

Compatibility

Designed as an OEM-style replacement for Class RK5 time-delay fuse applications in standard RK5-rated fuse holders and disconnect blocks rated for 600 volts and 2-1/8 amps or higher.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements for overcurrent protection devices. Always de-energize and lock out the circuit before removing or installing fuses. Verify that the fuse holder or disconnect block is rated for Class RK5 fuses at 600 volts before installation. Do not substitute a higher-amperage fuse to replace this device.
