Littelfuse LGR002 300V Small Dimension Fuse

Product Description

The LITTELFUSE LGR002 is a small dimension fuse rated at 300 volts, designed to provide overcurrent protection in compact electrical assemblies and control circuits. Its reduced physical footprint makes it well suited for tight panel layouts and equipment where standard fuse sizes do not fit. Electricians and controls technicians use this type of fuse when protecting low-voltage branch circuits, control transformers, and sensitive electronics from fault currents that could cause component damage or fire hazards.

This fuse is typically applied in residential and light commercial electrical panels, HVAC control boards, motor control centers, and industrial equipment where 300-volt rated overcurrent protection is required in a space-constrained location. Its small dimension form factor allows integration into fuse holders and blocks designed for compact fuse types, making it a common replacement component in preventive maintenance programs.

Key Features

• Rated for 300 volts, suitable for standard branch circuit and control circuit protection
• Small dimension body for installation in compact fuse holders and tight panel spaces
• Provides reliable overcurrent interruption to protect downstream components
• Manufactured by LITTELFUSE, a recognized name in circuit protection components

Compatibility

Designed as an OEM-style replacement small dimension fuse for 300-volt rated fuse holders and blocks requiring this compact form factor. Consult the equipment manufacturer documentation to confirm fuse amperage and interrupting rating before installation.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse amperage rating matches the original specification exactly — substituting a higher-rated fuse can defeat overcurrent protection and create a fire hazard. Use an approved fuse puller when servicing energized-adjacent panels.
