Eaton NOS-9 Class H Fuse 9 Amp 600 Volt

Product Description

The EATON NOS-9 is a Class H cartridge fuse rated at 9 amps and 600 volts AC. Class H fuses are one-time, non-renewable overcurrent protection devices used in branch circuit and feeder applications where basic short-circuit and overload protection is required. The NOS-9 fits standard cylindrical fuse holders and fuse blocks commonly found in residential and light commercial electrical panels, disconnect switches, and control equipment. Electricians and maintenance technicians install this fuse as a direct replacement or as original equipment in fused disconnects and load centers.

The NOS-9 is suited for residential and light commercial electrical systems requiring 600-volt rated overcurrent protection at 9 amps. Typical applications include motor branch circuits, lighting circuits, and general-purpose feeder protection in fused disconnect switches and safety switches. It is compatible with standard Class H fuse holders and rejection-style blocks that accept non-current-limiting fuses at this ampere and voltage rating.

Key Features

• 9-amp continuous current rating for precise overcurrent protection
• 600-volt AC rating suitable for standard branch circuit applications
• Class H designation fits widely available fuse holders and disconnect blocks
• One-time cartridge construction for straightforward replacement after fault clearing
• Compact form factor compatible with standard cylindrical fuse clips

Compatibility

Designed as an OEM-style replacement for standard Class H cartridge fuse holders and fused disconnect switches rated for 600 volts and 9 amps.

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 appropriately rated fuse puller when removing or installing cartridge fuses in live-adjacent equipment. Verify the replacement fuse matches the circuit's required ampere and voltage ratings before energizing.
