Certifications and Compliance

• For information on product certifications, code requirements, instructions for use, and detailed test conditions, refer to the certification details
• SCHURTER products are designed for industrial environments and are certified by independent testing organizations in accordance with national and international standards.

Certification reference type: UMK 250

• VDE certification: VDE certificate no.: 40027880/40023291
• UL certification: UR file no.: E41599

Product Standards

• Designed per IEC 60127-6: Miniature fuses. Part 6: Miniature fuse-holders
• Designed per IEC 60127-4: Miniature fuses. Part 4: Universal modular fuse-links for through-hole and surface mount types
• Designed per UL 248-14/4248-1: Low-voltage fuses - Part 14: Supplemental fuses
• Designed per CSA 22.2 No. 248.14/No. 4248.1: Low-voltage fuses - Part 14: Supplemental fuses

Compliance

• This product complies with the following directives

UMF 250 (Au)

• Fuse with gold-plated cap, certification status: VDE mark, cURus, PSE JET

UMC 250

• Clip, certification status: VDE UG mark, cURus

UMK 250 = UMF 250 (Au) + UMC 250

• There is no separate certification for the combined fuse and clip UMK 250; however, the fuse and clip are each fully certified by VDE/UL individually. See above for details.
• During reflow soldering, the fuse must have gold-plated caps; otherwise the fuse and clip will be soldered together. For field replacement of the fuse, the standard UMF 250 fuse with tin-plated caps may be used.
• Replacement with a rated current exceeding 4 A in the clip is not permitted.
