Merit Brass TR1/10R Time Delay Fuse 0.1A 250V RK5 10 Pack

Product Description

The MERIT BRASS TR1/10R is a time delay (TD) fuse rated at 0.1 amps and 250 volts, classified under the RK5 fuse class. Time delay fuses are designed to tolerate brief inrush currents during motor start-up or transformer energizing without nuisance tripping, while still providing reliable overcurrent protection under sustained fault conditions. This fuse is sold in a pack of 10, making it a practical stocking item for electrical contractors and service technicians who regularly service panels, control circuits, and motor branch circuits requiring RK5-class protection.

RK5 class fuses are commonly used in residential, light commercial, and industrial electrical systems where branch circuit and supplemental overcurrent protection is required. The TR1/10R is suited for low-amperage control circuits, instrumentation panels, and motor control centers. Electricians and HVAC technicians frequently stock this type of fuse for control board protection, transformer secondary circuits, and other low-current applications. The 10-per-pack quantity supports service van inventory and reduces per-unit cost for frequent installers.

Key Features

• Time delay design tolerates motor inrush and transformer energizing without nuisance trips
• RK5 class rating meets applicable branch circuit and supplemental protection standards
• Rated 0.1 amps at 250 volts for low-current circuit protection
• Sold in a 10-per-pack quantity for efficient job-site stocking
• Compact form factor suitable for standard fuse holders and fuse blocks

Compatibility

Designed as an OEM-style replacement for RK5-class time delay fuses in residential and light commercial electrical control and branch circuit applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for overcurrent protection. Always de-energize and lock out the circuit before replacing any fuse. Verify that the replacement fuse amperage and voltage ratings match the original fuse and the circuit requirements before restoring power. Do not substitute a fuse of a higher amperage rating to resolve nuisance trips — diagnose the underlying fault first.
