Eaton Tag Fuse, 20A Current Rating, 690V Voltage - 20NHG000B-690 NH FUSE 20A 690V SIZE 000 GG MGL

This tag fuse is a high-capacity protective device designed for use in industrial and renewable-energy electrical systems. It operates at elevated voltages and provides overcurrent interruption for circuits where slow response and high fault tolerance are required. The device is intended for panel and switchgear mounting in heavy-duty installations.

Features and Benefits:

• 20A rating delivers sustained circuit protection for prolonged loads
• 690V voltage capability permits use on high-voltage distribution networks
• GG slow-blow characteristic handles transient inrush without nuisance operation
• High rupture capacity interrupts severe short-circuits for system safety
• Compliant with recognised DIN and IEC formats ensures interchangeability

Applications

• Suitable for wind turbine electrical protection in nacelle and converter circuits
• Ideal for solar PV 690V DC arrays and string protection
• Used with industrial switchgear in manufacturing plants
• Can be used for utilities distribution feeders and substation protection
• Suitable for heavy-duty machinery requiring slow-blow overcurrent devices

What mounting format does it adopt for integration into switchgear?

It uses the standard NH/size000 tag format compatible with DIN-style fuse holders for inline installation in fuse blocks.

How does the slow-blow behaviour affect motor start-up protection?

The time-delay characteristic tolerates motor inrush currents, reducing unwanted fuse operation during normal starting cycles.

Which standards govern its rated performance and interchangeability?

Performance follows established IEC 60269 series and DIN 43620 dimensional references applicable to industrial fuses.

Is the product suitable for environments requiring restricted hazardous-arc handling?

Its high rupture capability is specified for interrupting high fault currents, mitigating energetic fault effects in heavy-duty systems.
