Fuse holders with UL approval

Before implementing a UL configuration, it is mandatory that you contact your UL certificate authority and discuss the necessary boundary conditions. When using fuse holders, care must be taken that they have also been tested and manufactured in accordance with the applicable standards of the UL certificate authority.

The integrated protection against short circuit is no substitute for the external fuse protection of the supply network. The fuse protection must comply with the manufacturer’s data as well as the national and international regulations and laws.

Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the National Electrical Code and any additional local codes.

Use UL mains fuses of the class “J”.

For alternatives to Class J UL fuses, be sure to refer to the UL standard “UL 508A, Chapter SB4.2.3, Exception No. 1”.

Depending on the achievable SCCR level, various fuse protection options are available.
