Eaton NH Fuse, 20A Current Rating, 500V Voltage - 20NHG000B
This NH fuse provides overcurrent protection for industrial electrical systems, designed to interrupt fault currents in low-voltage distribution installations. It operates as a cartridge-style protective element for circuits requiring gG/gL characteristics and is intended for use where high interrupting capacity and standards-compliant performance are required.
Features and Benefits:
• Rated for 20A to protect against sustained overloads
• 500V AC rating permits use in higher-voltage distribution circuits
• High rupture capacity to safely clear significant short-circuit events
• Complies with IEC 60269 to meet international interruption criteria
• Tag width 6mm simplifies identification and labelling during maintenance
• 500V AC rating permits use in higher-voltage distribution circuits
• High rupture capacity to safely clear significant short-circuit events
• Complies with IEC 60269 to meet international interruption criteria
• Tag width 6mm simplifies identification and labelling during maintenance
Applications
• Suitable for distribution panels in industrial plants
• Ideal for protection of motor feeder circuits in automation systems
• Used for safeguarding switchgear in electrical installations
• Can be used for replacements in systems requiring VDE 0636 compliance
• Ideal for protection of motor feeder circuits in automation systems
• Used for safeguarding switchgear in electrical installations
• Can be used for replacements in systems requiring VDE 0636 compliance
What approvals ensure international compatibility for system design?
The device meets IEC 60269 standards and carries approvals aligning with VDE 0636 and DIN 43620 dimensions for integration into recognised distribution frameworks.
How does the fuse behave under short-circuit conditions?
It exhibits high rupture capacity performance, enabling Rapid interruption of large fault currents to limit damage to upstream and downstream equipment.
What installation considerations apply to its form factor?
The cartridge-style unit has Compact overall measurements of 79 x 51 x 21mm, allowing installation in standard NH holders and enclosures designed for similar cartridge sizes.
How is circuit identification facilitated during service?
A 6mm tag width accommodates clear labelling to aid safe isolation and quick identification in maintenance procedures.
