Eaton NH Fuse Link 20A 500V gL/gG Size 000

The Eaton NH Fuse Link 20A 500V gL/gG Size 000 is a professional-grade electrical component engineered for robust circuit protection in industrial environments. This fuse link is designed to interrupt fault currents effectively, safeguarding electrical distribution systems, control panels, and industrial machinery from the risks associated with overloads and short circuits. With its standardized size 000 dimensions and reliable gL/gG characteristic, it ensures consistent operation and high breaking capacity under demanding conditions.

Advantages

This fuse link offers exceptional reliability and safety for critical electrical infrastructure. Its gL/gG characteristic provides a versatile protection profile, covering both low-level overloads and high-level short circuits, which makes it an essential component for maintaining system integrity. The robust construction ensures long-term durability and stable performance even in environments subject to thermal stress, minimizing the risk of unexpected downtime and protecting expensive downstream equipment from damage.

Suitable for

• Industrial electrical distribution boards
• Motor control centers
• Power supply protection in manufacturing facilities
• General electrical installation and maintenance

This fuse link may not be suitable for applications requiring specialized high-speed protection for sensitive power electronics or for circuits operating at voltages exceeding 500V. It is also not intended for use in residential consumer units where standard miniature circuit breakers are typically employed.

Key specifications

• Rated current: 20A
• Rated voltage: 500V AC
• Utilization category: gL/gG
• Size: 000
• Mounting type: NH fuse base

To use the Eaton NH fuse link, ensure the power supply is completely disconnected before installation. The fuse must be inserted into a compatible size 000 NH fuse base using an appropriate insulated fuse handle or extraction tool. Verify that the fuse is seated firmly in the contacts to ensure proper electrical connection and prevent overheating due to high contact resistance.

What to consider before purchase

• Verify that the current rating of 20A matches your circuit requirements
• Ensure the fuse base is compatible with size 000 NH fuse links
• Check that the system voltage does not exceed 500V
• Confirm the application requires gL/gG general-purpose protection

Always replace blown fuses with a new unit of the exact same rating and characteristic. Never attempt to repair or bypass a fuse, as this compromises the safety of the entire electrical system.
