Class H Fast-Acting Renewable Fuse
Product Description
The Class H Fast-Acting renewable fuse is engineered for use in environments where the available short-circuit currents do not exceed 10,000 amperes. These fuses can accommodate an ampere range from 3 to 600 A, making them versatile for various general purpose loads. The product's design includes a cylindrical body style and utilizes a ferrule blade connection terminal type.
Compliance with UL standards is ensured, as the fuse is UL Listed to Standard 248-7 and CSA Certified to Standard C22.2, No. 248.7, with certification files available for reference. The body is constructed from FWGE material and is compatible with lead-free applications. In addition, the fuse meets CE conformity and is ROHS compliant, further enhancing its suitability for modern electrical systems.
The fast-acting characteristic of this fuse provides immediate response to overcurrent conditions, safeguarding circuits effectively. For replacement, the RLS series die-cut zinc replacement links are recommended, available in a range of amperages to match specific requirements.
