Merit Brass TRS1/2R Time Delay Fuse 0.5A 600V RK5

Product Description

The MERIT BRASS TRS1/2R is a 0.5 amp, 600 volt Class RK5 time-delay fuse designed for overcurrent protection in electrical distribution and control circuits. Time-delay fuses of this type allow temporary inrush currents to pass without nuisance tripping, then respond quickly to sustained overload and short-circuit conditions. This fuse is installed by licensed electricians in branch circuit panels, motor control centers, disconnect switches, and industrial control equipment where reliable, selective overcurrent protection is required.

This fuse is suited for residential, commercial, and light industrial electrical systems requiring Class RK5 protection. Typical applications include motor branch circuits, HVAC equipment disconnect protection, and control panel fusing where a time-delay characteristic is specified by the equipment manufacturer or design engineer. Its compact size fits standard fusible disconnect and panel equipment accepting Class RK5 fuse elements at this ampere rating.

Key Features

• 0.5 amp rating for low-current branch circuit and control circuit protection
• 600 volt rating suitable for standard single-phase and three-phase distribution systems
• Class RK5 time-delay design prevents nuisance tripping on motor and transformer inrush
• Drop-in replacement form factor for Class RK5 fusible equipment

Compatibility

Designed as an OEM-style replacement Class RK5 time-delay fuse for use in fusible disconnects, panelboards, and motor control equipment rated for 600 volts and accepting standard Class RK5 fuse dimensions at 0.5 amps.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize and lock out the circuit before removing or installing fuses. Verify that the replacement fuse ampere rating and class match the equipment nameplate and circuit design exactly. Never substitute a higher-ampere fuse or a non-time-delay fuse in place of a time-delay type without engineering approval.
