Mersen TR2/10R Time Delay Fuse 2/10A 250V RK5

Product Description

The MERSEN TR2/10R is a time delay fuse rated at 2/10 amp and 250 volts, classified to the RK5 fuse standard. Time delay fuses of this type are designed to tolerate brief inrush currents without opening, making them well suited for protecting motors, transformers, and other inductive loads that draw high startup current. The RK5 classification indicates a rejection-style fuse that provides a higher level of protection than standard Class H fuses. This fuse is a direct-plug replacement intended for use in fusible disconnect switches, control panels, and distribution equipment serviced by licensed electricians and qualified electrical contractors.

This fuse is used in residential, commercial, and light industrial electrical systems where overcurrent protection is required for circuits operating at up to 250 volts. Typical applications include motor branch circuits, HVAC equipment disconnect switches, and control circuit protection. Its compact size fits standard fuse holders and fusible disconnect blocks designed for RK5-class fuses.

Key Features

• Time delay design tolerates motor and transformer inrush currents without nuisance opening
• 2/10 amp (0.2A) current rating for low-current circuit protection
• 250 volt rating suitable for single-phase and control circuit applications
• RK5 rejection-class construction prevents installation in lower-rated fuse holders
• Direct replacement fit for standard RK5-compatible fuse holders and disconnects

Compatibility

Designed as an OEM-style replacement for RK5-class time delay fuse applications in fusible disconnect switches and control panels rated up to 250 volts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lockout/tagout the circuit before removing or installing any fuse. Verify that the replacement fuse amperage and voltage ratings match the requirements of the overcurrent protective device schedule for the circuit. Never substitute a fuse of a higher amperage rating than specified by the circuit design.
