What are the standards for fuse holders?

Fuse holders are subject to various standards and regulations to ensure their safety, performance, and compatibility with electrical systems.

The specific standards applicable to fuse holders may vary depending on the region, industry, and intended use. Here are some commonly recognized standards for fuse holders:

1.International Electrotechnical Commission (IEC) Standards:

·IEC 60269: This standard specifies the general requirements for low-voltage fuses, including fuse holders.
·IEC 60947-3: This standard covers the requirements for low-voltage switchgear and controlgear, including fuse switches and fuse disconnectors.

2.Underwriters Laboratories (UL) Standards:

·UL 4248-1: This standard covers fuseholders for use in electrical appliances.
·UL 512: This standard applies to fuseholders for fuses rated up to 600 volts.
3.Canadian Standards Association (CSA) Standards:

·CSA C22.2 No. 39: This standard covers general requirements for low-voltage fuses and fuseholders.
·CSA C22.2 No. 39.1: This standard specifies additional requirements for fuseholders for use in specific applications.
4.American National Standards Institute (ANSI) Standards:

·ANSI C37.41: This standard provides guidelines for the design, testing, and performance of high-voltage expulsion and current-limiting fuses and their associated fuseholders.
It’s important to note that different industries and applications may have additional standards or specific requirements for fuse holders. For example, automotive fuse holders may need to meet standards set by organizations such as the Society of Automotive Engineers (SAE) or Original Equipment Manufacturer (OEM) specifications.

When selecting a fuse holder, it is crucial to consider the specific standards and regulations applicable to your region and industry. Compliance with these standards helps ensure the safety, reliability, and compatibility of the fuse holder within the electrical system.

Manufacturers typically provide information on the relevant standards their fuse holders comply with, and markings or certifications may be present on the fuse holder indicating its compliance with specific standards.
