Littelfuse LGR001 300V Small Dimension Fuse

Product Description

The LITTELFUSE LGR001 is a small-dimension fuse rated at 300 volts, designed for overcurrent protection in electrical and electronic circuits. Small-dimension fuses in this class serve as sacrificial overcurrent devices, interrupting fault current before downstream components are damaged. The LGR series is commonly installed in control panels, HVAC equipment, and light commercial electrical systems where space constraints require a compact form factor. Licensed electricians and HVAC technicians typically specify this fuse when replacing failed protection devices in tight enclosures or on equipment control boards.

The LGR001 is suited for residential and light commercial applications where a 300-volt rated small-dimension fuse is required. Typical installation scenarios include equipment control boards, motor control circuits, and panel-mount fuse holders. This fuse is appropriate for low-voltage control circuits and line-voltage circuits up to 300 volts where the compact body style is specified by the equipment manufacturer.

Key Features

• 300-volt rating for use in standard residential and light commercial circuits
• Small-dimension form factor for installations with tight space requirements
• Sacrificial overcurrent device protects downstream components from fault current
• LITTELFUSE LGR series construction for reliable interruption performance

Compatibility

Designed as an OEM-style replacement for small-dimension fuse applications rated at 300 volts in residential and light commercial electrical and HVAC control systems.

Installation Notes

Fuse replacement should be performed by a licensed electrician or qualified HVAC technician. Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse matches the voltage rating and physical size specified on the equipment nameplate or wiring diagram. NEC guidelines apply to overcurrent protection device selection and installation.
