Mersen RF5 Renewable Fuse 250V

Product Description

The MERSEN RF5 is a 250-volt renewable fuse designed for use in electrical overcurrent protection applications. Renewable fuses allow the internal fusible element to be replaced after operation, extending the service life of the fuse body and reducing replacement costs over time. This type of fuse is commonly installed in disconnect switches, panelboards, and industrial control equipment where reusable overcurrent protection is specified. Licensed electricians and electrical maintenance technicians are the primary installers of this component.

The RF5 is suited for electrical systems operating at up to 250 volts where a renewable-style fuse is required. Typical installations include light commercial and industrial distribution panels, motor circuits, and legacy equipment that specifies renewable fuse technology. This fuse type remains common in facilities performing maintenance on older electrical infrastructure.

Key Features

• Renewable design allows fusible element replacement after operation, extending fuse body service life
• Rated for circuits up to 250 volts
• Compatible with standard renewable fuse holders and disconnect switches designed for this form factor
• Reduces per-incident replacement cost compared to non-renewable fuse types

Compatibility

Designed as an OEM-style replacement renewable fuse for use in 250-volt disconnect switches, panelboards, and industrial control equipment that accept renewable fuse configurations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before removing or installing fuses. Verify that the replacement fusible element matches the original ampere rating before reassembly. Do not operate renewable fuse holders with missing or damaged fuse body components.
