Littelfuse NLS010 600V Class H Fuse

Product Description

The LITTELFUSE NLS010 is a Class H fuse rated at 600 volts, designed to provide overcurrent protection in electrical distribution systems. Class H fuses are one-time, non-renewable fuses used in branch circuit and feeder protection applications. The NLS010 interrupts fault current to protect wiring, equipment, and downstream components from damage caused by overloads and short circuits. Licensed electricians and electrical contractors typically install and service this type of fuse in panel boards, disconnect switches, and fusible equipment.

The NLS010 is suited for residential, commercial, and light industrial electrical systems where 600-volt Class H branch circuit fuse protection is required. It is installed in standard Class H fuse holders and fusible safety switches. Typical applications include motor branch circuits, feeder protection, and general-purpose electrical distribution equipment requiring UL-recognized overcurrent protection.

Key Features

• 600-volt rating suitable for standard branch circuit and feeder applications
• Class H one-time fuse construction provides reliable overcurrent interruption
• Compatible with standard Class H fuse holders and fusible disconnect switches
• Compact form factor for use in panel boards and safety switches

Compatibility

Designed as an OEM-style replacement for standard 600-volt Class H fuse applications in residential and commercial electrical distribution equipment.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before replacing a fuse. Use an approved fuse puller when removing or installing fuses in energized panels to reduce arc flash risk. Verify the replacement fuse amperage and voltage rating match the circuit requirements before reinstalling.
