Merit Brass TRS1/10R Time Delay Fuse 0.1A 600V RK5

Product Description

The MERIT BRASS TRS1/10R is a time delay fuse rated at 0.1 amps and 600 volts, classified in the RK5 fuse class. Time delay fuses in this class are designed to withstand brief inrush currents without nuisance tripping, while still providing reliable overcurrent protection for sustained fault conditions. The RK5 classification indicates a rejection-type fuse body that prevents installation in non-RK-rated fuse holders, reducing misapplication risk. This fuse is used by licensed electricians and control panel technicians in branch circuit and equipment protection applications.

The TRS1/10R is suited for low-amperage circuit protection in industrial control panels, motor circuits, and sensitive electronic equipment where time delay characteristics are required. Its 600-volt rating makes it appropriate for both single-phase and three-phase distribution circuits operating at standard commercial and light industrial voltages. The rejection-style design limits substitution with lower-rated fuse classes, supporting proper circuit coordination.

Key Features

• 0.1 amp (1/10A) rating for very low-current circuit protection
• 600-volt AC rating suitable for commercial and industrial distribution circuits
• RK5 rejection-class body prevents installation in non-compatible holders
• Time delay characteristic handles inrush current without nuisance tripping
• Compact fuse form factor for use in standard RK5-rated fuse holders and panels

Compatibility

Designed for use in RK5-rated fuse holders and fuse blocks rated for 600 volts AC and 0.1 amps or higher. Consult the fuse holder manufacturer specifications to confirm proper fitment before installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit completely before removing or installing any fuse. Verify that the fuse holder is rated for RK5-class fuses and that the circuit voltage and amperage do not exceed the fuse ratings. Never substitute a higher-amperage fuse to restore power without first identifying and correcting the fault condition.
