IEC 60269-2 Low Voltage Fuses - Test for Fuses to be Used by Authorized Persons

EUROLAB laboratory provides testing and compliance service within the scope of IEC 60269-2 standard. This standard provides additional requirements for fuses for use by authorized persons and are generally intended for use in installations where fuse links are accessible and can only be replaced by authorized persons.

Fuses to be used by authorized persons according to the following fuse systems also comply with the requirements of the relevant sub-clauses of IEC 60269-1, unless otherwise specified in this standard. This standard is devoted to insurance systems, each of which deals with a specific example of standardized fuses for use by authorized persons:

• Fuse system A: Blade contact fuse-link fuses (NH fuse system),
• Fuse system B: Mutual fuses blade contact fuses (NH fuse system),
• Fuse system C: Fuse rails (NH fuse system),
• Fuse system D: Fuse bases for busbar mounting (NH fuse system),
• Fuse system E: Fuse-link fuses for bolted connections (BS bolt-on fuse system),
• Fuse system F: Cylindrical contact fuse-link fuses caps (NF cylindrical fuse system),
• Fuse system G: Fuse-link fuses with offset blade contacts (BS clip-on fuse system),
• Fuse system H: fuse-linked fuses with "gD" and "gN" characteristics (class J and delay and non-delay fuse types),
• Fuse system I: gU fuses with wedge clamping contacts,
• Fuse system J: characteristics of "gD class CC" and "gN class CC" fuses (class CC time-delay and non-delay fuse types),
• Fuse system K: fuse links gK with blades for bolted connections.

High fuse links (main fuse links) from A to 4 800 A. This fifth edition of IEC 60269-2 cancels and replaces the fourth edition published in 2010.
